GZEXE(1)							      GZEXE(1)

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.
