Passing output to variable instead of file
Hi,
In normal shell scripting, how do you pass the output of a command to a variable, instead of a file and be able to use it later?
The code is:
#!/bin/bash
who | cut -d" " -f1 > onlineusers
Instead of passing the output of the above command to the file called 'onlineusers' highlighted in red, how do you pass the output to a variable or to any other sort of container and could be made use of later?
