Make a Bash alias that takes a parameter?

Question

I used to use CShell (csh), which lets you make an alias that takes a parameter. The notation was something like

alias junk=\"mv \\\\!* ~/.Trash\"
         


        

Answer 1

Here's are three examples of functions I have in my ~/.bashrc, that are essentially aliases that accept a parameter:

#Utility required by all below functions.

alias trim="sed -e 's/^[[:space:]]*//g' -e 's/[[:space:]]*\$//g'"

:< /tmp/history

        #Clear all items in the current sessions history (in memory). This
        #empties out $HISTFILE.
        history -c

        #Overwrite the actual history file with the temp one.
        mv /tmp/history "$HISTFILE"

        #Now reload it.
        history -r "$HISTFILE"     #Alternative: exec bash
    else
        echo "Cancelled."
    fi
}
