How to make an alias with a variable, for example I want to execute such a command sudo systemctl {{название}} start
And then call for example ctl mongodorctl nginx

Answer 1

sudo systemctl {{name}} start

didn't you mess up by chance?
maybe so ?
If yes, then it's easier than ever:
alias ctl="sudo systemctl start"

Answer 2

Create a file in any directory from $PATH ( echo $PATH)

cd /usr/bin
touch ctl

put something like this in it:

#!/bin/bash
sudo systemctl $1 start
