How to use aliases defined in .bashrc in other scripts?

Question

In ~/.bashrc, I defined some aliases. But I cannot use them in other shell scripts, where I can only use aliases defined right there. Even though I sourced bashrc, it still

Answer 1

The simplest answer is to do the 2 important things or it wont' work.

#!/bin/bash -i

# Expand aliases defined in the shell ~/.bashrc
shopt -s expand_aliases

After this, your aliases that you have defined in ~/.bashrc they will be available in your shell script (giga.sh or any.sh) and to any function or child shell within such script.

If you don't do that, you'll get an error:

your_cool_alias: command not found
