NAME
       bzexe - compress executable files in place

SYNOPSIS
       bzexe [ name ...	 ]

DESCRIPTION
       The bzexe 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 ``bzexe /bin/cat'' it will create the follow‐
       ing 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
       bzip2(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 exe‐
       cutable relies on the PATH environment variable to find gzip and some other utilities (tail, chmod, ln, sleep).

BUGS
       bzexe attempts to retain the original file attributes on the compressed executable, but you may have to fix them man‐
       ually in some cases, using chmod or chown.
