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 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

       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  executable  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 manually in some cases, using chmod or chown.
