hi

I have a script to login from a host "A" to a list of hosts in a file and perform some commands inside it...its somethin like this

for i in `cat file`
do
ssh -t $i " command1 ; command2; ..."
done

I wanna save the outputs in a file in the current host "A" i.e from where I am running this script.. Any help pls..
