You're using the wrong syntax. To open a file (for writing + truncation): exec 2>file To open a file (for appending): exec 2>>file To close a file descriptor: exec 2>&- The command that you ran (exec 2>&test1) redirects stderr which is normally opened to the terminal. In order to get it back, you would need to do something like exec 2>&1 assuming stdout has not been altered yet. The shell prompt is normally written to stderr, so you won't see the prompt until stderr is restored.
