       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
       /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.

       -d     Decompress the given executables instead of compressing them.

       gzip(1), znew(1), zmore(1), zcmp(1), zforce(1)

       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).

       gzexe  attempts  to  retain  the  original file attributes on the com-
       pressed executable, but you may have to  fix  them  manually  in  some
       cases, using chmod or chown.
