GZEXE(1)                                                              GZEXE(1)



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.
