## 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 un‐
       compress and execute when you run them (at a penalty in performance).  For example if you ex‐
       ecute ``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.

## CAVEATS
       The compressed executable is a shell script. This may create some security holes. In particu‐
       lar,  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._
