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  pen-
       alty   in   performance).    For	  example   if	 you  execute  ``gzexe
       /usr/bin/gdb'' it will create the following two files:
	   -rwxr-xr-x  1 root root 1026675 Jun	7 13:53	/usr/bin/gdb
	   -rwxr-xr-x  1 root root 2304524 May 30 13:02	/usr/bin/gdb~
       /usr/bin/gdb~ is	the original file and /usr/bin/gdb is the  self-uncom-
       pressing	 executable  file.   You can remove /usr/bin/gdb~ once you are
       sure that /usr/bin/gdb 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  se-
       curity  holes.	In particular, the compressed executable relies	on the
       PATH environment	variable to find  gzip	and  some  standard  utilities
       (basename, chmod, ln, mkdir, mktemp, rm,	sleep, and tail).

BUGS
       The  gzexe  command  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.
