Assigning nawk output to variables
I do a lot of command line scripting to capture data from files or other command output. I've checked in a number of Unix and scripting books but for the life of me I can't find out how to asign field data from nawk output into variables that I can manipulate later. For example, reading a two column file like /etc/hosts:
cat /etc/hosts | nawk '{print $1 "\t" $2}'
How can I get $1 and $2 into variables like $IP and $NAME?

then
page = 3 (9 Replies)
