Alias ​​in linux scripts?

Question

linux

Hello, why doesn't alias work in scripts? I run the script, for example, with alias ll="ls -l", but after executing it, no new alias is added. What could be the problem?

Answer 1

Aliases only work in interactive shell mode.
When run in scripts, they will not work.
If you need, use functions - they can also replace alias and will work in scripts
