GZEXE(1)                                              General Commands Manual                                              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
       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.
