3 gzexe \- compress executable files in place
10 utility allows you to compress executables in place and have them
11 automatically uncompress and execute when you run them (at a penalty
12 in performance). For example if you execute ``gzexe /bin/cat'' it
13 will create the following two files:
16 -r-xr-xr-x 1 root bin 9644 Feb 11 11:16 /bin/cat
17 -r-xr-xr-x 1 bin bin 24576 Nov 23 13:21 /bin/cat~
19 /bin/cat~ is the original file and /bin/cat is the self-uncompressing
20 executable file. You can remove /bin/cat~ once you are sure that
21 /bin/cat works properly.
23 This utility is most useful on systems with very small disks.
27 Decompress the given executables instead of compressing them.
29 gzip(1), znew(1), zmore(1), zcmp(1), zforce(1)
31 The compressed executable is a shell script. This may create some
32 security holes. In particular, the compressed executable relies
33 on the PATH environment variable to find
35 and some other utilities
36 .I (tail, chmod, ln, sleep).
39 attempts to retain the original file attributes on the compressed executable,
40 but you may have to fix them manually in some cases, using
