/bin/ls | rand [-lw] [-o <output file>]
file usage:
rand [-lw] -f COPYING [-o <output file>]
other:
rand [-vh]
Installation: read INSTALL.
Bug reports:
email br0ke@math.smsu.edu, provide as much useful info as possable.
What to do with this? well, you can queue up programs in a random order... someone was complaining about mpg123 not having a 'shuffle' command (which it does), this could provide that. A teacher writing a test could use this to generate tests that have the same questions but in different order... etc etc etc. One interesting use was a sysadmin using this to scramble 'script kiddies' exploit sources. While not completely ethical, it's terribly amusing :)
Thanks to Dr Shade <shade@csc.smsu.edu> (Southwest Missouri State University)
for redoing the randomizing algorithm to be lightening fast. O(n^2) to O(n).
