For example try this: cp /bin/cat ~/mycat vi ~/mycat <now editing in vi> [esc] :%!xxd <now editing mycat in hex> <find some innocuous string or rcsid> <change the values on the hex side> [esc] :%!xxd -r [esc] :wq! ./mycat <somefile> You can also 'pre' xxd transform the file, then edit it, then transform it back when finished. --- Mark atkin901 at NOSPAM yahoo dot com (!wired)?(coffee++):(wired);
