Unix - Error while creating aliases.

You don't say what Unix you are using, but on my FreeBSD system I get a similar error. The form of the alias command differs according to the shell that you are using (although I thought the form that you were using was correct for ksh). Anyway, try omitting the = sign: alias ls 'ls -ltr' That worked on my system.

In the Korn shell, use: alias ls="ls -ltr" Don't use single quotes. Use double quotes.

Thru my own bad experience, I'd like to warn you that it is a really bad idea to alias common unix commands to act differently. It's a sure bet that sometime in the future, you'll run another shell script which will fail because it expects ls to act as originally designed.
