I find I often want to have the return status from a command used in an if statement but I don't seem to be able to get the syntax correct. As an example, I'd really like to be able to combine these two following statements:



into just one if statement. It seems that [ chokes on the |. What am I missing?

Hi buchs,

There are many ways:
Note that none will work in scripts, because aliases are not available in them.

Watael,

Thanks for your reply! I knew it was that easy. You've taught me several new things. I did not realize that aliases are not expanded, by default, in scripts (non-interactive). However, I see you can enable that with shopt -s expand_aliases. But, the setting/unsetting and listing of aliases occurs in either case, so the forms you gave in your reply will work in a script.

I appreciate your help.
