who command
 
Hi guys

What Bash script do I use to test the true of false results of the command 'who | grep pts'
how do I assign the results to a variable?
Thank you
Dory

Hi, and welcome to LQ!


The result is in $?

Code:
who | grep pts > /dev/null 2>&1
result = $?

Cheers,
Tink

echo $? produces 1 or 0

result = $? #produces an error( -bash: results: command not found )

thanks
Dory

Sorry about that; give the spaces around the = a miss.
And yes, 0 is success, 1 is failure.


Cheers,
Tink
