       gzexe - compress executable files in place


       gzexe name ...


       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-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.


       -d     Decompress the given executables instead of compressing them.

       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  standard  utilities
       (basename, chmod, ln, mkdir, mktemp, rm, sleep, and tail).


       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.
