!!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 /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


__-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 other utilities ''(tail, chmod, ln,
sleep).''
!!BUGS


''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.''
