bash shell script which adds output of commands
- by John Kube
Let's say I have a command called foo which prints a number to the screen when called:
$foo
3
Let's also say I have another command called bar which prints another number to the screen when called:
$bar
5
I'm looking to write a shell script which will add together the output of foo and bar. How would I do that? (The outputs from the commands are not known ahead of time. They just so happen to have been 3 and 5 the last time they were run. They could have been something else.) Thanks!
