    Trim out control characters in a field.

    tr -d '[[:cntrl:]]'

    You forgot the most important use for tr which is to implement a rot13 encoder-decoder; that is translate between the range a-m and n-z.

    # tr a-z n-za-m
    # tr a-zA-Z n-za-mN-ZA-M

    There is a mistake point 6. Should be -s not -d.

  4. Paul says:

    -s command is incorrect in your post. You currently have -d showing in the example. Other than the syntax error and that one example it’s a pretty good introduction to the TR command.

  5. Ed says:

    You did not show -s option example in paragraph 6. Instead you showed the -d ' '.
