If you get this error, you probably have one of the following things wrong:

  • You've forgotten the slash and semicolon in the find command. Use find command like this:
    # find /tmp -mtime +5 -type f -exec rm {} \;
  • If you get this error from crontab, then you should add an extra slash to the slash and semicolon. Use the find command like this:
    0 2 * * * find /tmp -mtime +5 -type f -exec rm {} \\;
