.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.
