Hm, I tried to test that before I sent that. But I guess my test was faulty since I was really testing what process the terminal handling delivered the signal to: $ cat /tmp/test.sh #!/bin/sh echo before sleep 5 || echo sleep failed echo after $ sh /tmp/test.sh ; echo $? before ^\ /tmp/test.sh: line 4: 23407 Quit sleep 5 sleep failed after 0 -- Gregory Stark EnterpriseDB http://www.enterprisedb.com ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
