I have a script for avoiding to derail running shell scripts (which are not protected against changes): echo usage : prep_edit fileaddress echo Renames file, copies its content to old name and unlinks renamed original echo Thus protecting any potentially open filedescriptors from upcoming echo changes of the file content. Good for active shell scripts. It is not safe against race conditions, though. No new starts of the fileaddress should happen while prep_edit is running (for a short time). Have a nice day :) Thomas
