Get output from 2 lines and create a variable for bash scripting
 
Hello

When i am running a command i am getting as an output:

Code:
appId: f2cn26bf033c3afx
key: 5d54478c8a29a20aa8a2df1718cda545
How can i get them as separated variables so i can use them at a bash script?

Thank you !

Pretty sure you can pipe that into awk and use print along with argument numbers to grab each piece, $1 $2

so essentially, you want bash to eval this:
Code:
appId="f2cn26bf033c3afx"
key="5d54478c8a29a20aa8a2df1718cda545"
???
Code:
help eval
PS: eval is potentially harmful.

Please show what you have tried and / or what you are familiar with?

I will check the @rtmistler recommendation....

Thank you

reader.sh < key-value.txt

Code:
# reader.sh
while IFS=": " read -r k v; do
 case "$k" in
  "appId") appId="$v" ;;
  "key") key="$v" ;;
 esac
done

echo "appId = $appId"
echo "key = $key"
Instead of echoing the key/values you could add some logic to act on each pair that it finds. Not sure what you wanted to do, but this might be a good place to start.

Please clarify your "it" and show the working solution for others to learn from :)
