NAME
gzexe - compress executable files in place
SYNOPSIS
gzexe name ...
DESCRIPTION
The gzexe 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 exam-
ple if you execute ``gzexe /usr/bin/gdb'' it will create the
following two files:
-rwxr-xr-x 1 root root 1026675 Jun 7 13:53 /usr/bin/gdb
-rwxr-xr-x 1 root root 2304524 May 30 13:02 /usr/bin/gdb~
/usr/bin/gdb~ is the original file and /usr/bin/gdb is the
self-uncompressing executable file. You can remove
/usr/bin/gdb~ once you are sure that /usr/bin/gdb works
properly.
This utility is most useful on systems with very small
disks.
OPTIONS
-d Decompress the given executables instead of compressing
them.

CAVEATS
The compressed executable is a shell script. This may cre-
ate some security holes. In particular, the compressed exe-
cutable relies on the PATH environment variable to find gzip
and some standard utilities (basename, chmod, ln, mkdir,
mktemp, rm, sleep, and tail).
BUGS
gzexe 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.
