				.TH GZEXE 1				.SH NAME				gzexe \- compress executable files in place				.SH SYNOPSIS				.B gzexe				[ name ...  ]				.SH DESCRIPTION				The				.I  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:				.nf				.br				    -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~				.fi				/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.				.PP				This utility is most useful on systems with very small disks.				.SH OPTIONS				.TP				.B \-d				Decompress the given executables instead of compressing them.				.SH "SEE ALSO"				gzip(1), znew(1), zmore(1), zcmp(1), zforce(1)				.SH 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				.I gzip				and some other utilities				.I (tail, chmod, ln, sleep).				.SH "BUGS"				.I gzexe 				attempts to retain the original file attributes on the compressed executable,				but you may have to fix them manually in some cases, using				.I chmod				or				.I chown.
