>>> 1 + 1
2
>>> x = _
>>> x

wish helps you foo=$(ls)
You can use $(your command) to get the output of your command.

Hope that helps Then I call command in my bash script like command it's outputs to my terminal but isn't saving anywhere. If I want to save output I use output=$(command) but now command output isn't showing to my screen unless command would be completed so I can call echo "${output}". But the problem is: I don't want to wait until command will be completed. So, is there any way to call command, show output while it's running and later save everything to a variable? , I think you want a tool called tee:
code :
cat file1.txt | tee -a file2.txt
