This question already has an answer here:

When I set in .bashrc something like:

alias="docker stop $(docker ps -aq)"

or

alias="echo $(ls -l ~)"

obviously never refreshes the command output in $(), so is an string...

So, my question is, there is any way to refresh the command output used as variable ?

  • @glennjackman Yes, thank you, that’s was I looking for. Put it as answer, if you want, and I’ll mark it as correct. – xpeiro Apr 27 '18 at 14:50
