For example if you execute ``gzexe /usr/bin/gdb'' it +will create the following two files: +.nf +.br + -rwxr-xr-x 1 root root 1026675 Jun 7 13:53 /usr/bin/gdb + -rwxr-xr-x 1 root root 2304524 May 30 13:02 /usr/bin/gdb~ +.fi +/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. +.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" +.BR gzip (1), +.BR znew (1), +.BR zmore (1), +.BR zcmp (1), +.BR 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 +.B gzip +and some standard utilities +.RB ( basename , +.BR chmod , +.BR ln , +.BR mkdir , +.BR mktemp , +.BR rm , +.BR sleep , +and +.BR tail ). +.SH "BUGS" +The +.B gzexe +command +attempts to retain the original file attributes on the compressed executable, +but you may have to fix them manually in some cases, using +.B chmod +or +.BR chown . |
