system uses sh on unix platforms (if the string to execute includes shell meta characters). Is >! an sh feature on your system? On mine, as best as I can tell, your code would be a misuse of the ! reserved word.

Use the bourne shell syntax for what you are trying to do, or specify your shell explicitely:
system('/bin/mysh', '-c', 'pwd >! tmp_1');
