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 auto-
       matically 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.
