gzexe(1) -- Linux man page
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 /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), znew(1), zmore(1), zcmp(1), zforce(1)
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 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.
