Silly example, but might help.
#! perl -slw use POSIX qw(:errno_h :sys_wait_h); use constant { RET_SUCCESS => 1, RET_FAILURE => 0, }; sub check_process_signal { my $sig = shift; if ( WIFEXITED($sig) ) { print q{process normal exit}; return RET_SUCCESS; } elsif ( WIFSIGNALED($sig) ) { print q{process terminated because of signal}; return RET_FAILURE; } elsif ( WIFSTOPPED($sig) ) { print q{process is stopped}; return RET_FAILURE; } return RET_SUCCESS; } my $pid = #run your command however.... waitpid( $pid, 0 ); if ( check_process_signal( $? ) ) { ## success... } else { ## failure ... }

Coded on the fly sorry if there are any errors.
