di - disk information utility (version 4.44)

  Bugs and Known Issues
  Porting Information


  'di' is a disk information utility, displaying everything
  (and more) that your 'df' command does. It features the
  ability to display your disk usage in whatever format you
  prefer. It is designed to be highly portable. Great for
  heterogenous networks.


  To build:
    make -e dioptions.dat
    # Edit dioptions.dat and change it
    # to set your preferences.
    # Add your CC, CFLAGS and LDFLAGS settings.
    # This file will not be removed and can be reused
    # for the next release.
    make -e
    make -e install
  Example to change compiler and prefix:
    CC=gcc prefix=/opt/bin make -e

  If you don't have a bourne shell compatible shell,
  Try building with perl:
      make -e all-perl

  The CC, CFLAGS, CPPFLAGS, prefix, LDFLAGS, and LIBS environment
  variables may be set and exported prior to running make.  This
  will override any settings in 'dioptions.dat'.

  The LOCALEDIR environment variable defaults to ${prefix}/share/locale.
  The installation uses the INSTALL_DIR (default ${prefix}),
  ($INSTALL_DIR/share/locale) environment variables for installation.

  The internationalization files are automatically built and installed if
  your system supports internationalization.

  Windows installation:
    Alternative 1 - uses pre-built or config.mingw
      Cygwin gcc: make -e windows-gcc
        (uses cygwin API)
      MinGW: mingw32-make -e MAKE=mingw32-make CC=gcc windows-mingw
        (uses windows API)
      Msys2: make WINAPI=T NO_PIE=yes
    Alternative 2 - builds a new config.h file (Cygwin).
      make -e NO_PIE=yes CC=gcc
      make -e NO_PIE=yes CC=gcc WINAPI=T  # windows API
    Alternative 3 - builds a new config.h file (MSys)
      # make sure your PATH is set properly
      mingw32-make -e MAKE=mingw32-make \
        _MKCONFIG_SHELL=bash WINAPI=T NO_PIE=yes CC=gcc

    You may need to change _lib_GetDiskFreeSpaceEX to 0
    in the config.h file for older windows systems.

    Some versions of gcc on HP-UX break the include files.
    If you see:    header: rpc/rpc.h ... no
    try: env CC=gcc CFLAGS="-D_LABEL_T" make -e

    On some HP-UX systems, quotactl isn't declared.
    If you want quota support, make sure config.h has:
      #define _lib_quotactl 1
      #define _args_quotactl 4
      #define _c_arg_1__quotactl int
      #define _c_arg_2__quotactl char *
      #define _c_arg_3__quotactl int
      #define _c_arg_4__quotactl caddr_t
      #define _quotactl_pos_1 0
      #define _quotactl_pos_2 1

      env CFLAGS="-z +Z +DD64" LDFLAGS="+DD64" make -e
    64-bit gcc:
      env CC=gcc CFLAGS="-fPIC -mlp64 -D_LABEL_T" \
          LDFLAGS="-mlp64 -L/usr/lib/hpux64" make -e
      env CFLAGS="-z +Z +DD32" LDFLAGS="+DD32" make -e
    32-bit gcc:
      env CC=gcc CFLAGS="-fPIC -milp32 -D_LABEL_T" \
          LDFLAGS="-milp32 -L/usr/lib/hpux32" make -e
    Bundled cc:
      cd C;make hpux-cc

    export BIN_SH=svr4 beforehand.

    If quotas are not turned on in the kernel (/boot/loader.conf),
    the vquotactl interface will not be configured into di.  The
    default build available from DragonFly dports does not have
    the vquotactl interface turned on.

  Installation Permissions:
    Some old systems (Sys V variants) only allow root to read the
    mount table.  In SysV.4 and Solaris, the mount command would
    reset the permissions to be root readable only (fixed in Solaris 7).

    If this is needed on your system, do:
        make installperms

    The Tcl extension provides access to the di utility via
    the [diskspace] command.

    To build:

      cd C; make -e tcl-sh

      Windows Cygwin:
        cd C; make CC=gcc NO_PIE=yes tcl-sh
      Windows Msys:
        cd C; make WINAPI=T NO_PIE=yes CFLAGS=-m64 tcl-sh

    See C/di-example.tcl for a usage example.

    The Perl extension provides access to the di utility via
    the [Filesys::di::diskspace] command.

    To build:

      # perl-perl can be substituted for perl-sh to use the
      # perl configuration script instead of the shell
      # configuration scripts.
      cd C; make -e perl-sh; cd Perl; make PREFIX=your-prefix install

      Windows Cygwin:
        # I had to install libcrypt-devel for 'crypt.h'.
        # No idea why perl would require that.
        # perl-perl is faster than perl-sh.
        cd C; make CC=gcc NO_PIE=yes perl-perl
      Windows Msys:
        # untested; I don't have mingw perl.
        cd C; mingw32-make -e MAKE=mingw32-make \
          _MKCONFIG_SHELL=bash WINAPI=T NO_PIE=yes CC=gcc perl-sh

    See C/Perl/ex/ for a usage example.

    What's Not Tested:
      - pooled filesystems on Tru64.
        - I have access to a Tru64 system w/quotas, but there's
          only one filesystem per pool.
      - quotas:
        - MacOSX
          - No access to users with quotas.
      - MS VC++ has not been tested in a *very* long while.
      - A/UX, Cray, Irix, UNICOS, Next, Pyramid, SCO Unix, Sequent
        have not been tested in a *very* long while.
    Known Issues
      - quotas:
        - Solaris ufs requires the quotas file to be readable, or make
          the di program setuid.  Neither recommended.
        - Linux 2.4 - not working
        - HP-UX
          - quotactl() isn't declared. See HP-UX section above.
        - NetBSD 6
          - group quotas can't be fetched by ordinary users (EPERM).
            If the account is limited by a group quota, it won't be reported.
        - AIX 7
          - Unlike AIX 5, AIX 7 gives a permission
            denied error when a user tries to get their quota.
            Could make di suid, but that's not a good idea.
      - pooled filesystems:
        - hammer: the usage reported for pseudo-filesystems is the usage
          for the main pool.  Therefore the total used and size will be wrong.
        - btrfs: there's no way to identify the pools.
      - cygwin with clang does not work.

    Send bug reports along with the output from 'di -A -a -X 5',
    output from your standard df command (as verbose as possible),
    mkconfig.log, mkconfig_env.log, di.env, and config.h to:

    If the 'config.h' doesn't get set up correctly, please let me know.
    E-mail me the incorrect (and corrected if possible) config.h file,
    and any other information as appropriate.

        Fixed check of exabyte sized filesystems.  The signed check now

        HP-UX bcc seems to support long long after all.  This is on 11.11.
          Maybe the older versions did not?  No access to 10.20.

        Fixed features/
        Makefile cleanup (Mike Frysinger).

    4.20                                    [2010-3-7]
        Added VMS.
        Fixed totals for pooled filesystems, again

    4.19                                    [2010-2-1]
        Fix totals to add up when using small block sizes.
        Fix totals for mixed pooled and non-pooled filesystems.
        Add fix for automounted directories:
        Builds on BSD 4.3.
        Changed format of config.h file.
        Code cleanup.

    4.18                                    [2009-11-29]
        Code cleanup.

        The default configuration method has been changed to
        use a shell script.  The perl configuration script is
        still available (./Build -mkpl).

    4.17                                    [2009-11-22]
        Totals have been changed to add up whatever filesystems
        are displayed.  This is more intuitive for the user.
        It is up to the user to exclude read-only filesystems
        (cdfs, iso9660), memory-based filesystems (memfs, mfs, tmpfs)
        and user filesystems (fuse*).  Excluding the 'fuse' type will
        exclude all fuse* filesystems.

        As before, only the main pool of a pooled filesystem is totaled.

        The build now works on unixware (getmntent is in libgen).
        The build now works on syllable.

        The default configuration method has been changed to
        use the perl script.  Removed iffe, as it doesn't support
        class testing.

    4.16                                    [2009-9-20]
        Fixed a nested macro issue on Mac OS X 10.6.
        Fixed bugs with filename arguments.

    4.8                                     [5 Oct 2006]
        Linux's statvfs() is not POSIX compliant and does not
        use f_frsize.  The correct value is returned in f_bsize.
        Since there's no way to tell which type of statvfs() is
        in use, we have to hard-code the logic for linux.
        This sucks.

        Add logic to find the correct msgfmt program to use.
