gzexe - compress executable files in place
2. SYNOPSIS ▲
gzexe "name . . ."
3. 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 example if you execute ``gzexe /usr/bin/gdb'' it will create the following two files:
/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.
4. OPTIONS ▲
Decompress the given executables instead of compressing them.
5. SEE ALSO ▲
6. 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 standard utilities ( basename , chmod , ln , mkdir , mktemp , rm , sleep , and tail ).
7. 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 .
