RedHat [Solved] Argument list with awk
Hello,

I want to execute remote command with ssh.
For exemple, i have a variable
Code:
SERVERS=lpar1,lpar2,lpar3

I want to execute some commands like:

Code:
ssh -q lpar1 ls /
ssh -q lpar2 ls /
ssh -q lpar3 ls /

Can you help me with awk command ?

Thank you Smilie

I don't know why you requested for a solution based on awk! I think it is an overkill when you can do it simply in shell:
Code:
SERVERS=lpar1,lpar2,lpar3

for host in ${SERVERS//,/ }
do
        ssh -q $host "ls /"
done
