Bash Script with Arguments

Have you ever wondered to input the arguments in the bash scripts. Well there is the process how you do it.

Step 1: add the following script on the top of bash script file (test.sh)

# passing the arguments

while [ $# -gt 0 ]; do

if [[ $1 == *"--"* ]]; then

        v="${1/--/}"

declare $v="$2"

fi

shift

done

echo $appName $version # this one is passed as an arguments

Step 2: pass the name of variable that you want to access in as an arguments something like this

./test.sh –-appName App1 –-version v1.2

What a great way isn’t it?
