#!/bin/sh # gzexe: compressor for Unix executables. # Use this only for binaries that you do not use frequently. # # The compressed version is a shell script which decompresses itself after # skipping $skip lines of shell commands. We try invoking the compressed # executable with the original name (for programs looking at their name). # We also try to retain the original file permissions on the compressed file. # For safety reasons, gzexe will not create setuid or setgid shell scripts. # WARNING: the first line of this file must be either : or #!/bin/sh # The : is required for some old versions of csh. # On Ultrix, /bin/sh is too buggy, change the first line to: #!/bin/sh5 # Copyright (C) 1998, 2002 Free Software Foundation # Copyright (C) 1993 Jean-loup Gailly # This program is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2, or (at your option) # any later version. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
