Assign awk multiple variables

Question

I'm using this command to check all sshd processes and CPU USAGE and CMD for sshd deamon:

ps -C sshd -o %cpu,cmd

example of output:

%CPU CMD
 0.0 sshd: root [priv]
 0.0 sshd: aadmin@pts/1

After that i've used:

ps -C sshd -o %cpu,cmd | awk '!/%CPU/ {print $1, $3}'

Output:

0.0 root
0.0 aadmin@pts/1

To sort CPU USAGE and third line, what i want is to assign awk output var to have output like this for multiple processes and in separate lines.

CPU_USAGE=0.0 USER=root
CPU_USAGE=0.0 USER=aadmin@pts/1

I've tried to assign variable to awk with awk -v but without success

Maybe I'm missing something here but couldn't you just change your print to print "CPU_USAGE="$1, "USER="$3? — Tom Fenech

@EtanReisner yes, like this CPU_USAGE=0.0 USER=root CPU_USAGE=0.0 USER=aadmin@pts/1 — klerk

It's not clear what any of this has to do with variables. Can you update your question to explain what you mean? — Tom Fenech

It's also not clear what any of it has to do with To sort CPU USAGE and third line. Sort what? What third line? — Ed Morton

ps -C sshd -o %cpu,cmd | awk '!/%CPU/ {printf("CPU_USAGE=%s USER=%s\n", $1, $3)}'

You just have to format your print statement, for that, use printf.

Or shorter:

ps -C sshd -o %cpu,cmd | awk '!/%CPU/ {print "CPU_USAGE="$1, "USER="$3}'

Hope this is what u want. Your question was not clear otherwise...
