It is ``trap <action> <signal>'' so for the signal part this may be right that this is made uppercase. But action is not modified I guess. So it should be exit because there is no built-in named EXIT in bash:

$ type exit exit is a shell builtin $ type EXIT bash: type: EXIT: not found

So for me it does not seem to work:

$ trap 'err=$?; echo trap; EXIT $?' 0 $ exit 5 exit trap bash: EXIT: command not found [1] 12906 exit 5 bash
