exit - End the application SYNOPSIS
exit ?returnCode? _________________________________________________________________ DESCRIPTION
Terminate the process, returning returnCode to the system as the exit status. If returnCode isn't specified then it defaults to 0. EXAMPLE
Since non-zero exit codes are usually interpreted as error cases by the calling process, the exit command is an important part of sig- nalling that something fatal has gone wrong. This code fragment is useful in scripts to act as a general problem trap: proc main {} { # ... put the real main code in here ... } if {[catch {main} msg]} { puts stderr "unexpected script error: $msg" if {[info exist env(DEBUG)]} { puts stderr "---- BEGIN TRACE ----" puts stderr $errorInfo puts stderr "---- END TRACE ----" } # Reserve code 1 for "expected" error exits... exit 2 } SEE ALSO
