bzexe - compress executable files in place
[ name ... ]
utility allows you to compress executables in place and have them
automatically uncompress and execute when you run them (at a penalty
in performance). For example if you execute ``bzexe /bin/cat'' it
will create the following two files:
/bin/cat~ is the original file and /bin/cat is the self-uncompressing
executable file. You can remove /bin/cat~ once you are sure that
/bin/cat works properly.

-r-xr-xr-x 1 bin bin 24576 Nov 23 13:21 /bin/cat~
This utility is most useful on systems with very small disks.
Decompress the given executables instead of compressing them.

The compressed executable is a shell script. This may create some
security holes. In particular, the compressed executable relies
on the PATH environment variable to find
and some other utilities
(tail, chmod, ln, sleep).
attempts to retain the original file attributes on the compressed executable,
but you may have to fix them manually in some cases, using
