Hello Robert,

I'm glad you found the patch helpful. About the way it is being
displayed on your dmenu, I think sed might be configured differently
on our machines. It does actually just display "my-alias" when I use
it. This line is the likely culprit:


> alias | sed 's/alias \([[:alnum:]]\+\)=.*/\1/'

Run this as a standalone command on your machine and see what happens.
Ideally, it should only display a list of alias names, not their
expansions or any '=' sign. But if your output is the same as just
running "alias" all by itself, the sed is simply not working. My best
guess: you have sed configured to use extended syntax. In that case,
something like this should solve your problem:

> alias | sed -r 's/alias ([[:alnum:]]+)=.*/\1/'

The -r is not really needed if your system is already configured to
add it by default, but this makes sure it works regardless of what the
default is on your system.

Let me know if this helps (or doesn't help)
