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 /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-uncompressing	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 security holes.  In particular, the compressed ex‐
       ecutable	 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.
