Capturing stdout into a variable

697 views bash

This might be a naive question, but I'm really not sure how to do it. I submit a spark job and I get the following output.

Run job succeeded. Submission id: driver-20170824224209-0001

I want to programmatically query the status of this job. How can I use the output in the console to extract the id to a variable using a bash script. Any help appreciated.

Do you mean when you run a program, it outputs that string Run job... and you want to get the id from that string into a variable?

Let's say you command is cmd and you want to store the out put of the command in say a variable called res, one way in bash is to run the command in single quotes


or embed the command within $()
