gzexe

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.
