Can Bash aliases be nested?

For example if I have a setup like:

 alias llaa = pwd && ll'''

Will the second command work, or would I have to set it up in a more verbose manner (like ```alias llaa = pwd && ls -la```)

Should work. Just try it out and see if you get what you want. I tried:

alias llaa='pwd && ll'

then ran llaa and it did what I expected, current directory and the output of ls -al which is aliased.

Yes. How about just trying it out?

I think you don't want the spaces around the= sign. Preferred over alias is function llaa { ... }. Alias is for backwards compatibility.

Again what learned. What is wrong with having spaces around the equals sign, though?

I think it might not work with the spaces. But if it does, then you are fine.

Ah, obviously you're right and bash is less tolerant to spaces than I've had in my mind:

You can declare aliases that will last as long as your shell session by simply typing these into the command line. The syntax looks like this:
alias alias_name="command_to_run"
Note that there is no spacing between between the neighbor elements and the equal sign. This is not optional. Spaces here will break the command.

You wanna use double quotes to wrap it:

alias llaa="pwd && ll'''"
