I would like to make an alias like this:
alias where "who | grep \!:1 | awk '{print $6}' -"
which would output the originating host of the user caled for. I have
tried all kinds of permutations of quote characters, etc, with no luck. I
ended up making the awk portion into a one-liner script and piping to that
instead.
This command works fine on the command line, but not as an alias. Can
anybody tell me what I am doing wrong/should do?
Thanks very much,

You need to protect the $6 from being expanded by the shell when the alias command is executed, and you also need to protect it from being expanded by the shell when the alias itself is being executed. The following works: alias where "who | grep \!:1 | awk" \''{print $6}'\' - because the unescaped single quotes protect the $6 from expansion when the alias command is executed, and the escaped single quotes become part of the alias and protect the $6 from expansion when the alias itself is executed.
