I have variable $OUTPUT=abc PHYSIN=lalala ghi
How can I extract the value of PHYSIN into another new variable called VETH_NAME,
in other words, I'd like VETH_NAME to be lalala
How can I do so using bash commands?
Thanks

Assuming this is what you are saying :
OUTPUT="abc"
PHYSIN="lalala ghi"
VETH_NAME=$(echo "$PHYSIN" | cut -d" " -f1)
finally :
echo $VETH_NAME
lalala

Use parameter expansion with the %% operator, which drops the longest matching suffix from the expansion.
OUTPUT=abc
PHYSIN="lalala ghi"
VETH_NAME=${PHYSIN%% *}

I notice this is basically identical to your answer to stackoverflow.com/questions/15148796/… - perhaps you'd like to review the Stack Overflow

I have tried; I link to some of the questions frequently, but don't pretend to memorize all the links on that page. Questions like this are far faster to whip out an answer than to search for a duplicate.

Yeah, it's a struggle. But thanks for following up; just wanted to make sure you are aware. There's a link to a chat room down at the end if you'd like to participate at some later time. Cheers!
