gzexe(1)

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 executable relies on the
   PATH environment variable to find  gzip  and  some  standard  utilities
   (basename, chmod, ln, mkdir, mktemp, rm, sleep, and tail).

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.
