gzexe - compress executable files in place
gzexe name ...
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-
uncompressing 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.
-d 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 gzip and some standard utilities
(basename, chmod, ln, mkdir, mktemp, rm, sleep, and tail).
gzexe 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.
