NAME    [Toc]    [Back]

       gzexe - compress executable files in place

SYNOPSIS    [Toc]    [Back]

       gzexe [ name ...  ]

DESCRIPTION    [Toc]    [Back]

       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.

OPTIONS    [Toc]    [Back]

       -d     Decompress the given executables instead of compressing them.

SEE ALSO    [Toc]    [Back]

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

CAVEATS    [Toc]    [Back]

       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).

BUGS    [Toc]    [Back]

       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.
