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.
