compress executable files in place
name ... ]
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.
Decompress the given executables
instead of compressing them.
znew(1), zmore(1), zcmp(1), zforce(1)
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).
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.
