How to use this script as alias in bash !

Add this code to your ~/.bashrc

alias getasn="{{getasn.sh full path}}"

1. replace {{getasn.sh full path}} with path of where is getasn.sh script is save it and the run this code :

source ~/.bashrc

Now you can call getasn script anywhere in bash by only calling getasn ! And Only need to pass [options]

./getasn.sh -s -domainlist ListOfDomains.txt | notify -mf "done" -id discord

Good luck :)
