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. |
