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.
