. Shell procedures may use the trap command to catch or ignore Unix operating system signals . The form of the trap command is: trap ' command-list ' signal-list . Several traps may be in effect at the same time. If multiple signals are received simultaneously, they are serviced in ascending order. To check what traps are currently set use the trap command. For example: trap . Most common signals to be caught . Handling command lists . Examples .
