- .TH GZEXE 1
- .SH NAME
- gzexe \- compress executable files in place
- .SH SYNOPSIS
- .B gzexe
- [ name ... ]
- .SH DESCRIPTION
- The
- .I 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 /bin/cat'' it
- will create the following two files:
- .nf
- .br
- -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~
- .fi
- /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.
- .PP
- This utility is most useful on systems with very small disks.
- .SH OPTIONS
- .TP
- .B \-d
- Decompress the given executables instead of compressing them.
- .SH "SEE ALSO"
- gzip(1), znew(1), zmore(1), zcmp(1), zforce(1)
- .SH 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
- .I gzip
- and some other utilities
- .I (tail, chmod, ln, sleep).
- .SH "BUGS"
- .I gzexe
- attempts to retain the original file attributes on the compressed executable,
- but you may have to fix them manually in some cases, using
- .I chmod
- or
- .I chown.
