Index NAME
gzexe - compress executable files in place
SYNOPSIS
gzexe[ name ... ]
DESCRIPTION
The
gzexeutility allows you to compress executables in place and have themautomatically uncompress and execute when you run them (at a penaltyin performance). For example if you execute ``gzexe /bin/cat'' itwill create the following two files:
-r-xr-xr-x 1 root bin 9644 Feb 11 11:16 /bin/cat -r-xr-xr-x 1 bin bin 24576 Nov 23 13:21 /bin/cat~
/bin/cat~ is the original file and /bin/cat is the self-uncompressingexecutable file. You can remove /bin/cat~ once you are sure that/bin/cat 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 somesecurity holes. In particular, the compressed executable relieson the PATH environment variable to find
gzipand some other utilities
(tail, chmod, ln, sleep). BUGS
gzexe attempts to retain the original file attributes on the compressed executable,but you may have to fix them manually in some cases, using
chmodor
chown.
