Instead, I escape the command with a back-slash, which causes the actual
command to execute instead of the alias. This keeps the safety of the
alias but allows me to intentionally bypass it.
The command
\rm abc*
will ignore the alias and remove all files in the current directory
whose names begin with "abc" without any prompt for confirmation.
I escape the commands rm, cp, and mv when I use them in a script.
However, I don't escape them until after I have tested the script just
in case I have an error in the script.
