NAME
gzexe - compress executable files in place
SYNOPSIS
gzexe name ...
DESCRIPTION
The gzexe 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 ``gzexe
/usr/bin/gdb'' it will create the following two files:
-rwxr-xr-x 1 root root 1026675 Jun 7 13:53 /usr/bin/gdb
-rwxr-xr-x 1 root root 2304524 May 30 13:02 /usr/bin/gdb~
/usr/bin/gdb~ is the original file and /usr/bin/gdb is the self-uncom-
pressing executable file. You can remove /usr/bin/gdb~ once you are
sure that /usr/bin/gdb works properly.
This utility is most useful on systems with very small disks.
OPTIONS
-d Decompress the given executables instead of compressing them.

CAVEATS
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 gzip and some standard utilities
(basename, chmod, ln, mkdir, mktemp, rm, sleep, and tail).
BUGS
The gzexe command attempts to retain the original file attributes on
the compressed executable, but you may have to fix them manually in
some cases, using chmod or chown.
