- The _g_z_e_x_e 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:
- -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.

- The compressed executable is a shell script. This may cre-
- ate some security holes. In particular, the compressed
- executable relies on the PATH environment variable to find
- _g_z_i_p and some other utilities _(_t_a_i_l_, _c_h_m_o_d_, _l_n_, _s_l_e_e_p_)_.
-
- BBUUGGSS
- _g_z_e_x_e attempts to retain the original file attributes on
- the compressed executable, but you may have to fix them
- manually in some cases, using _c_h_m_o_d or _c_h_o_w_n_.
