Bash Version: 4.1 Patch Level: 5 Release Status: release Description: Event-catching seems to be catching cases it shouldn't. In particular, $! is caught as an event. Repeat-By: This command fails as follows: > nicku...@woking:~$ sleep 5 & PID=$!; echo "pid is $PID" > bash: !: event not found Adding quotation marks doesn't help: > nicku...@woking:~$ sleep 5 & PID="$!"; echo "pid is $PID" > bash: !": event not found As a workaround, adding whitespace after the ! fixes it: > nicku...@woking:~$ sleep 5 & PID=$! ; echo "pid is $PID" > [1] 1614 > pid is 1614 or > nicku...@woking:~$ sleep 5 & PID="$! "; echo "pid is $PID" > [3] 2048 > pid is 2048
