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 exam-
ple if you execute ``gzexe /bin/cat'' it will 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-
uncompressing executable 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.
SEE ALSO
gzip(1), gznew(1), gzmore(1), gzcmp(1), gzforce(1)
CAVEATS
The compressed executable is a shell script. This may create
some security holes. In particular, the compressed execut-
able relies on the PATH environment variable to find gzip
and 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 chmod or chown.
