Removing aliases

There are two methods. One is permanent; the other overrides an alias for a single command. To remove an alias permanently use the unalias command. This accepts *?[ ] wildcards to match the defined aliases.

                             # Removes aliases called:
     % unalias myscript      # myscript
     % unalias kap_*         # kap_ followed by zero or more characters
     % unalias compres?      # compres followed by a single character
     % unalias [f-hz][2-5]   # One of f, g, h, or z then an integer
                             # between 2 and 5 inclusive

To override an alias, precede the alias with backslash. So suppose you have an alias to prevent you accidently removing a file as shown below.

     % alias rm rm -i

In a script where you know that you want to remove a file, you don't want the script to seek confirmation. So suppose you want to delete file myfile, then you would have a line like

     \rm myfile

in your script.
