Well I *thought* I had saved it ;-) I did try find / -mmin -60 but was deluged with unexpected stuff from the /proc and /dev file systems, and couldn't figure out how to use -prune so gave up on that. But I suspect the file might have been deleted by the Firefox plugin after I exited the editor.

Like 'grep -A 100 -B 100". -- best regards, Victor Churchill, Bournemouth -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --------------------------------------------------------------
