How to do some custom bash scripting command?

Question

I'd like to use some commands on my Orange pi zero within reach, for example: I want to execute one command on ubuntu, and I want to have every commands on 1 file.

my_file (without ending in .sh)

#!/bin/bash
alias myip='curl ipinfo.io/ip'
alias tururu='echo it works'

Have this file, and chmod -x was executed on this file, but when I do on terminal "sh my_file myip", doesn't do anything, but didn't give me an error, so what I'm doing wrong?

Thank you very much

I think you mean to: source my_file && myip

sh myfile myip is one command; it doesn't run sh myfile, then myip. Your script should just look like

#!/bin/sh
curl ipinfo.io/ip
echo it works

then run as sh myfile (or myfile, assuming it is executable and located in a directory on your path).

If, instead, you want to execute myfile so that you can subsequently use myip and tururu as commands, you need to source the file:

$ source myfile
$ myip
192.0.2.24
$ tururu
it works
