This may not count because it's not bash specifically or even Linux -> Linux, but one place you might run into this is running scripts between Linux and Mac/BSD

This may not count because it's not bash specifically or even Linux -> Linux, but one place you might run into this is running scripts between Linux and Mac/BSD. In the past I've seen bad things happen because a script was written by someone on OSX that gets run on a Linux (GNU) based system. Two common examples are the `sleep` and `sed` commands. Edit: I meant to reply to the parent comment.
