NAME
LLNL XDIR - A graphical network-oriented file manager
SYNOPSIS
xdir [standard X Window options]
DESCRIPTION
LLNL XDIR provides a graphical user interface for file transfer and
for direct manipulation of local and remote directories on UNIX (and a
number of non-UNIX) platforms. LLNL XDIR offers the ability to view
directory information in four different formats, ranging from long
lists to tree structures. LLNL XDIR is based on UNIX, the C
programming language, OSF/Motif and FTP; hence, LLNL XDIR is highly
portable.
With LLNL XDIR, you can manage virtually all of your files in a
network. Specifically, LLNL XDIR can be used to browse directory
structures, transfer files and directories, view local and remote
files, delete files and directories, rename files and directories, and
search directories on one or more hosts for entries matching a
specified pattern.
LLNL XDIR simultaneously displays any number of directories of any
number of (local or remote) hosts, with each directory being displayed
in its own window. Several existing products are able to manage files
on a single system, but LLNL XDIR extends this capability to manage
files on an entire network.
LLNL XDIR does not have a "main" window, as such, but instead consists
of a number of windows, each of which displays the contents of a local
or remote host's directory. Each of these "directory windows" has a
complete set of controls for setting modes and invoking operations.
Several other windows are provided for setting general preferences and
displaying diagnostic information.
LLNL XDIR offers elaborate directory-browsing functionality. Each
directory can be viewed in several different formats, ranging from
long lists to tree structures. A number of mechanisms are provided to
traverse directory structures, including: (1) double-clicking a
directory name/icon to enter that directory, (2) a "go to parent
directory" button, (3) a "go to home directory" button, and (4) a
sophisticated history mechanism for easily reentering previously
visited directories.
LLNL XDIR provides powerful file transfer capability using drag-and-
drop. It is just as easy to copy a file between two remote systems as
it is to copy a file from the local host to itself. Files and
directories may be transferred either singly or in groups with just a
few movements of the mouse.

One of LLNL XDIR's most powerful features is its ability to search
directory structures for entry names matching a specified pattern.
You are able to specify the range and depth of such searches. The
search can be restricted to a single subdirectory or can extend across
machine boundaries.
With LLNL XDIR, you are able to view local or remote files, using
either the built-in viewer or any combination of external viewers of
your choice (e.g., emacs or xv).
LLNL XDIR's history mechanism makes it simple to establish a
connection with a remote host. This and other features make it
especially painless to connect to an anonymous FTP site.
A number of directory-manipulation features are provided for operating
on selected entries. There are several ways to select a group of
directory entries to operate on, including direct toggling of entries,
sweeping out a rectangular area, and wildcard selection. Once entries
are selected, you are able to rename entries, delete entries
(including entire subdirectories), or move entries between directories
within the same host. You are also able to create directories, both
on local and remote hosts.
LLNL XDIR utilizes a history mechanism for automatically caching (1)
wildcard expressions used in selecting directory entries, (2)
previously visited directories, and (3) host/user name pairs used in
connecting to remote hosts. The purpose of each cache is to reduce
the amount of typing and mouse movement required. For example, when
you wish to apply a wildcard expression to select directory entries to
operate on, a list of recently referenced wildcard expressions for
that host will be presented; you can then double-click on an existing
wildcard expression to apply it. The caches are automatically
preserved across LLNL XDIR sessions.
LLNL XDIR presents a graphical user interface for easily tailoring the
program's behavior. You are able to specify such things as whether
you would like the delete operation to first pop up a verification
dialog listing the entries to be deleted.
Finally, an extensive on-line help facility, much of which is
contextual, is provided. However, experience has shown that the user
interface is so intuitive that the user rarely needs to access the
help package.
GETTING STARTED
When LLNL XDIR is started, a window appears that displays the contents
of a directory on the local host. This window is called a "directory
window." You can have any number of directory windows for any number
of hosts.

Use the Connect menu to connect to a remote host. Select Connect to
Anonymous to connect to an anonymous FTP site. Choose Connect to
Remote to connect to other remote hosts. A directory window will be
created for the specified host.
You can use a host's directory window to create another directory
window for that host, First make sure that tunneling mode is off for
that directory window (using the tunnel icon in the toolbar). Then,
simply change to another undisplayed directory by using any of the
following techniques: (1) double-click an entry name or icon that
represents a directory, (2) press the "go to parent directory" button
(the up-arrow button in the toolbar), (3) press the "go to home
directory" button (the house button in the toolbar), or (4) select an
item in the Goto menu. If tunneling mode happens to be on, the
current directory window is used to display the specified directory.
LLNL XDIR has several mechanisms to aid you in managing a
proliferation of directory windows: (1) directory windows may be
individually iconified (using the window manager), (2) all iconified
LLNL XDIR windows can be redisplayed by selecting Deiconify All in the
File menu, (3) any request to display a directory that is iconified or
buried under other windows causes its directory window to be brought
to the front, and (4) the Wins menu can be used to identify existing
directory windows and bring them to the front.
Change between different formats for displaying information within a
directory window by toggling the layout buttons in the directory
window's toolbar.
Many operations require that entries in a directory window first be
selected. Select/deselect entries by (1) single-clicking on an entry
(which toggles its selection state), (2) holding the left mouse button
down and dragging to sweep out a selection rectangle (which
individually toggles each entry's selection state), (3) selecting any
of the items in the directory window's Select menu, or (4) typing a
sequence of characters into a directory window to select the first
entry that most closely matches the characters.
Copy (i.e., transfer) selected entries by using the left mouse button
to drag the entries. The drop site of the drag can be (1) the
background of another directory window, (2) a directory entry in any
directory window (including the source directory window).
Directories, as well as files, can be transferred. LLNL XDIR does not
permit transfers from a remote host to itself. The desired file
transfer mode can be specified by using the option menu in the toolbar
of any directory window.
Move selected entries by using the left mouse button to drag the
entries, and holding down the control key when the mouse button is
released over the drop site. (A move differs from a transfer in that
(1) the source entries are destroyed, and (2) a move is usually
- 3 - Formatted: December 17, 2025

implemented by manipulating file system pointers rather than by
actually copying bits.) The drop site of the drag may be (1) the
background of another directory window, (2) a directory entry in any
directory window (including the source directory window). LLNL XDIR
only allows moves from a host to itself.
View selected files by selecting View Selected Entries in the
directory window's Ops menu. Also, you may double-click on an entry
that LLNL XDIR knows not to be a directory. Configure the viewer by
selecting item Viewer Preferences in the Prefs menu. Be sure to first
set the file transfer mode by using the option menu in the toolbar of
any directory window.
Delete selected entries by pressing the trash can button in the
toolbar. Directories, as well as files, may be deleted.
Search for an entry that matches a specified wildcard expression by
selecting Search in the Ops menu. You are able to specify the range
and depth of the search. After a match has been found, you can
continue the search by selecting Search Again in the Ops menu.
Some other operations on selected entries may be invoked by selecting
appropriate items in the directory window's Ops menu.
Configure LLNL XDIR by selecting the General Preferences item in the
Prefs menu.
DIRECTORY WINDOW TOOLBAR
Each directory window has a toolbar that can be used to set modes and
to invoke operations. From left to right, the toolbar controls are:
Transfer Mode (Option menu)
The option menu at the left allows you to choose the file
transfer mode (ASCII or Binary). This mode is global in scope;
hence, changing the value in one directory window will
automatically change the value in all directory windows.
Layout Mode (Group of four buttons)
The layout mode controls how the directory entries are displayed.
The first button selects "Tabular Layout," in which only the
entry names are displayed. The second button selects "Iconic
Layout," in which an icon and name is displayed for each entry.
In Iconic Layout, five different icons are used to identify the
entry type: directory, executable file, generic file, socket, and
link. The third button selects "Tree Layout," which is similar
to Iconic Layout except that each entry that is a directory also
has a small diamond-shaped button, which can be used to expand
and collapse the subdirectory. The last button selects "Full
Info Layout," which displays as much information about each
directory entry as possible (the amount of information available
- 4 - Formatted: December 17, 2025
xdir(1) xdir(1)

is limited by the host's FTP server).
Tunneling Mode (Button with picture of tunnel)
If "tunneling mode" is off, entering a directory that is not
already displayed will cause a new window to be created to
display that directory. If tunneling mode is on, an existing
directory window (the one from the which the command was invoked)
will be used to display a directory that does not already have it
own window.
Dot Files Mode (Button with dot in dog-eared page)
If "dot files mode" is on, then entry names that begin with a dot
(i.e., period) will be displayed.
Refresh Directory (Button with starburst shape)
Redisplay this window's directory.
Go To Parent (Up arrow button)
Display this window's parent directory.
Go To Home (House button)
Display the home directory of this directory window's host.
Delete (Trash can button)
Delete selected directory entries.
Make Directory (Button containing folder labeled "New")
Create a directory.
Close (Skull and cross bones button)
Get rid of this directory window.
DIRECTORY WINDOW COMMANDS
LLNL XDIR contains a large number of commands that can be invoked from
the directory windows. Most commands are invoked (1) from the menus,
(2) from the toolbars, and (3) by dragging and dropping directory
entries. Here is a list of the commands:
About LLNL XDIR (in File menu)
Give version information.
Close (in File menu and toolbar)
Remove (not iconify) this directory window. If this directory
window is the last for its host, the host is disconnected.
Connect to Anonymous (in Connect menu)
Easily connect to an anonymous FTP site. A dialog pops up to
prompt for the remote host, user name and password. The user
name is initialized to "anonymous". The password is initialized
to the value of the general preference Anonymous Ftp Password
- 5 - Formatted: December 17, 2025
xdir(1) xdir(1)
10 January 1995
(which you will probably want to set to your email address). If
the general preference Anonymous Ftp Password is blank, LLNL XDIR
will attempt to create a password of the form "user@host". An
optional, space-delimited port number may follow the host name.
Previously used host/user name pairs are cached, and those with
user names "anonymous" or "ftp" are displayed in the scrolled
list Recently Referenced Hosts. Double-clicking on a host/user
name pair initiates a connection. Single-clicking on a host/user
name pair places those values into the host name and user name
fields, where they can be edited. Click on the Connect button to
initiate a connection. (If already connected, a directory window
for that host is simply brought to the front.) (See general
preferences Add to Cache, Anonymous Ftp Password, Host Cache
Size, User Cache Size, and Sort Caches.)
Connect to Local (in Connect menu)
Connect to the local host (i.e., the host upon which LLNL XDIR is
executing). If already connected, an existing directory window
for the local host is brought to the front.
Connect to Remote (in Connect menu)
Connect to a remote host (use Connect to Anonymous to more easily
connect to an anonymous FTP site). A dialog pops up to prompt
for the remote host and user names. The user name is initialized
to the value of the environment variable USER. An optional,
space-delimited port number may follow the host name. Previously
used host/user name pairs are cached, and those with user names
other than "anonymous" and "ftp" are displayed in the scrolled
list Recently Referenced Hosts. Double-clicking on a host/user
name pair initiates a connection. Single-clicking on a host/user
name pair places those values into the host name and user name
fields, where they can be edited. Click on the Connect button to
initiate a connection. (If already connected, a directory window
for the host is simply popped to the top.) (See general
preferences Add to Cache, Host Cache Size, User Cache Size, and
Sort Caches.)
Contextual Help (in Help menu)
Enter contextual-help mode. The mouse cursor changes to a
pointing hand. Click on any graphical element in the directory
window that you wish to know more about.
Copy (drag-and-drop operation)
Copy (i.e., transfer) the selected files according to the mode
(ASCII or Binary) specified in the toolbar's file transfer mode
option menu. Copy selected items by using the left mouse button
to drag the items. The drop site of the drag can be (1) the
background of another directory window, (2) a directory entry in
any directory window (including the source directory window).
Directories, as well as files, can be transferred (but the
general preference Copy Mode must be set to Recursive). LLNL

Make Directory (in Ops menu and toolbar)
Pop up a dialog to prompt for the name of a directory to create
in the displayed directory.
Move (drag-and-drop operation)
Move selected entries from one directory to another on the same
host. Move selected items by using the left mouse button to drag
the items, and holding down the control key when the mouse button
is released over the drop site. (A move differs from a transfer
in that (1) the source entries are destroyed, and (2) a move is
usually implemented by manipulating file system pointers rather
than by actually copying bits.) The drop site of the drag can be
(1) the background of another directory window, and (2) a
directory entry in any directory window (including the source
directory window). LLNL XDIR only allows moves from a host to
itself. A dialog pops up to enable the user to monitor the
progress of the moves. This dialog contains a button for
aborting the move operations. (See general preferences Beep When
Ops Done, and Inquire on Move.)
Quit (in File menu)

Rename Selected Entries (in Ops menu)
Pop up a dialog to individually rename selected entries.
Save Preferences (in Prefs menu)
Save the current settings of the general, viewer, and launcher
preferences.
Search (in Ops menu)
Pop up a dialog to initiate a search of directory windows for
entry names that match a specified pattern. The pattern to be
matched can contain the usual wildcard characters ('*', '?', '[',
and ']'). The toggle item Match Case controls whether case
(upper or lower) should be considered when looking for a match.
The Maximum Search Depth slider is used to specify the maximum
number of directory levels the search command will explore when
looking for an entry that matches the specified pattern. Choose
one of the toggle items, Search this directory, Search all
displayed directories of this host, or Search all displayed
directories of all hosts, to specify which directory windows (and
their descendants) are to be searched.
When the OK button is pressed, a dialog appears to monitor the
progress of the search. This dialog contains a button that can
be used to abort the search.
If a match is found in a directory that is already displayed, the
entry is selected, scrolled into view, and its directory window
is brought to the front. If a match is found in a directory that
is not already displayed, there are two cases: If the search was
initiated from a directory window with tunneling mode on, the
entry's directory is displayed in that directory window;
otherwise a new window is created to display the entry's
directory.
Use Search Again to continue the search once an entry has been
found. (See general preferences Beep When Ops Done, Initial Max
Search Depth, Initial Search Case Match, and Initial Search
Range).
Search Again (in Ops menu)
Search for the next entry that satisfies the search criteria
specified by the last search command. (See general preference
Beep When Ops Done).
Select All Entries (in Select menu)
Select all the entries in this window.
Send Quoted Command (in Ops menu)
Pop up a dialog to prompt for a "raw" command to send to the FTP
server of the remote host. Previously issued commands are cached
and displayed in a scrolled list. Double-clicking on a command
- 9 - Formatted: December 17, 2025
xdir(1) xdir(1)
10 January 1995
in the list issues that command. To have a command act on
selected entries, use the quote placeholder ("%s") to represent a
selected item. For example, type "stage 1 %s" to send a STAGE
command to the the remote host for each selected entry. (See
general preference Beep When Ops Done.)
Use Wildcard (in Select menu)
Pop up a dialog to prompt for a wildcard expression to use in
selecting entries in this directory window. Previously
referenced wildcard expressions are cached and displayed in a
scrolled list. Double-clicking on an item in the list applies
that wildcard expression. Single-clicking on an item in the list
places the expression in a text field where it may be edited.
Choose the toggle item Replace Selection to cause the currently
selected entries to be cleared before applying the wildcard.
Choose the toggle item Add to Selection to cause the entries
selected by the wildcard to be added to the current selection.
(See general preference Initial Wildcard Mode).
Using Help (in Help menu)
Describe the online help package.
View Selected Files (in Ops menu)
Display the selected files. The viewer preferences dialog
(accessible via the Prefs menu) can be used to control whether
files will be displayed using the built-in viewer or using an
external viewer of the user's choice (e.g., emacs or xv). The
selection of the viewer is configurable, based on the file
extension (e.g., ".gif" or ".jpg").
The file is transferred according to the mode (ASCII or Binary)
specified in the toolbar of the directory window. A dialog pops
up to enable the user to monitor the progress of the transfer.
This dialog contains a button for aborting the transfer.
The destination of the transfer is a temporary directory created
in the directory defined as P_tmpdir in the include file
"/usr/include/stdio.h". If the environment variable TMPDIR is
defined, it is used as the directory. The temporary directory,
and the files it contains, are automatically deleted when the
user dismisses the viewer or terminates LLNL XDIR.
If the file is recognized as being compressed, it is expanded
before viewing. LLNL XDIR excutes the following decompressors
based on the file extension: gunzip for ".z" and ".gz";
uncompress for ".Z"; atob for "atob"; and uudecode for ".uu".
LLNL XDIR searches for the decompressor application in the
standard way using the PATH environment variable.

GENERAL PREFERENCES
Selecting item General Preferences in a directory window's Prefs menu
pops up a dialog that allows you to configure LLNL XDIR according to
your preferences. You are presented with a number of configuration
parameters, which are set by either toggling, sliding, or typing.
Click the Apply button to cause the new values to take effect. The OK
button has the same effect as Apply, but the dialog is also closed.
The Cancel button undoes changes made since OK or Apply were last
pressed. The preferences can be preserved across LLNL XDIR sessions
in a text file named ".xdirrc" in your home directory. You may alter
the order the preferences are presented in the dialog by (1)
terminating LLNL XDIR, (2) using a text editor to change the order of
lines in ".xdirrc" and (3) restarting LLNL XDIR.
Add To Cache

Specifies whether to automatically enter the most recently
referenced directory after connecting to a host. If this option
is requested, but is not possible to perform (e.g., because the
directory no longer exists), your home directory will be entered.
User Cache Size
The number of user names to cache (for remote hosts). The cache
is preserved across LLNL XDIR sessions.
Wildcard Cache Size
The number of wildcard expressions to cache. The cache is
preserved across LLNL XDIR sessions.
VIEWER PREFERENCES
Selecting item Viewer Preferences in a directory window's Prefs menu
pops up a dialog that allows the user to control which file will be
displayed with which viewer, based on the file extension.
A file to be viewed is first transferred to a temporary directory and
then, if necessary, is decompressed. The file extension (e.g.,
".gif") is then examined to determine which viewer the file is to be
displayed in. There are two types of viewers: the viewer built into
LLNL XDIR (which is suitable for displaying text files) and external
viewers (e.g., emacs for text and xv for graphics).
Single-click on an entry in the Extensions list to place that
extension and its associated command line into the Extension and
Viewer Command Line text fields, respectively.
An extension is a file suffix that begins with a period ("."). A
special entry in the extensions list, "OTHERS," represents all files
that do not have their extension listed (including files with no
extensions).
The pattern "%s" in a command line is a placeholder for the name of
the file to be viewed. A blank command line indicates that the
built-in viewer is to be used. To add a new extension to the list,
fill in the Extension and Viewer Command Line text fields and press
the Add button. If the text in Extension does not begin with a

it will be replaced.

To replace the command line associated with an extension, (1) single-
click on the list item to select it, (2) edit the command line, and
(3) press the Replace button.
To delete an extension from the list, single-click on the list item to
select it and then press the Delete button. The "OTHERS" entry cannot
be deleted (but its command line can be replaced).
Click the Apply button to cause the new changes to take effect. The
OK button has the same effect as Apply, but the dialog is also closed.
The Cancel button undoes the changes made since OK or Apply were last
pressed.
The viewer preferences can be preserved across LLNL XDIR sessions in a
text file named ".xdirrc" in the user's home directory (select Save
Preferences in a directory window's Prefs menu).
LAUNCHER PREFERENCES
Selecting item Launcher Preferences in a directory window's Prefs menu
pops up a dialog that allows the user to specify commands that can be
invoked using the Launch submenu of the Ops menu. The idea is to be
able to fork and exec child processes with execute lines based on
information about selected entries.
Single-click on an entry in the Command Names list to place that
command name and its associated command line into the Command Name and
Command Line text fields, respectively.
The following placeholders can be specified in a command line: "%u"
for the user name, "%h" for the host name, "%s" for the name of a
selected entry, and "%l" for the blank-delimited names of all selected
entries. To add a new command to the list, fill in the Command Name
and Command Line text fields and press the Add button. If the command
name is already in the list, it will be replaced.
To replace the command line associated with a command name, (1)
single-click on the list item to select it, (2) edit the command line,
and (3) press the Replace button.
To delete a command from the list, single-click on the list item to
select it and then press the Delete button.
Click the Apply button to cause the new changes to take effect. The
OK button has the same effect as Apply, but the dialog is also closed.
The Cancel button undoes the changes made since OK or Apply were last
pressed.
The launcher preferences can be preserved across LLNL XDIR sessions in
a text file named ".xdirrc" in the user's home directory (select Save
Preferences in a directory window's Prefs menu).

The names of the commands will be placed in the Launch submenu of the
Ops menu. (See command Launch in section Directory Window Commands
for details on how commands are actually launched.)
LIMITATIONS
Here are some things to watch out for:
LLNL XDIR might not work with some old X servers. For example, some
older OpenWindows servers might dump core. MacX fans should use
nothing older than version 1.1.7b.
Old, buggy versions of Motif can cause weirdness.
LLNL XDIR might not work correctly with some non-Unix FTP servers.
(If you can give us temporary access to such a server, we might be
able to fix the problem.)
Out-of-spec FTP servers can cause untold grief. (Most Unix-based
servers work correctly.)
Third-party file transfers will not work unless at least one of the
remote FTP servers supports the PASV (passive) command.
