Ssh with awk
hello, I wish to launch a command ssh by getting back certain values in a file with awk. Example of command ssh: Code:
ssh -q lpar1 mount|grep /tmp/conf-1 ssh -q lpar2 mount|grep /tmp/conf-1 Example of file: Code:
/tmp/conf-1 servers=lpar1 lpar2 lpar3 /tmp/conf-2 servers=lpar4 lpar5 lpar6 |

In that case, Code:
var="/tmp/conf-1 servers=lpar1 lpar2 lpar3"
echo $var | sed 's/=/ /g' | awk '{for(i=3;i<=NF;i++){print "ssh -q "$i" mount|grep "$1}}'This should work

Sure it's possible, but awk is not shell, and ill-suited to it. Code:
awk 'BEGIN { "ssh whatever" | getline }'It'd be much better to run ssh outside of awk, and pipe it in. |
