BZEXE(1)                             General Commands Manual                             BZEXE(1)



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  par‐
       ticular,  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.
