.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 "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.
