Ok, thank you for clarifying. There is nothing in the documentation about this behavior as far as I can tell. I would suggest adding a line about traps getting reset after a failed exec to the paragraph on 'execfail'.

When the shell runs `exec', it assumes the execed program will overlay the shell process. To make that happen transparently, it has to undo things it has done: it ends job control and restores the original process groups, it restores the signal dispositions that it got from its parent, and it clears other shell state like the EXIT trap. If the exec fails, it tries to restore some things as well as it can, but it doesn't try to restore any traps. -- ``The lyf so short, the craft so long to lerne.'' - Chaucer ``Ars longa, vita brevis'' - Hippocrates Chet Ramey, UTech, CWRU c...@case.edu http://tiswww.cwru.edu/~chet/
