I presumed you were communicating with this shell through a pipe. How are you communicating with the shell?	[reply]

No, I am writing the programm which installs ssh keys on remote servers. my @servers = ('j5'); foreach my $server (@servers) { my $cmd = "bash"; if (system($cmd)) { print "$cmd failed\n"; next; } my $res = qx(ssh $server); if ($res =~ m/RSA\skey\sfingerprint/) { HERE I NEED TO ANSWER YES/NO AND PRESS ENTER	[reply]

You need something like IPC::Open2 instead of `qx()` since you want 2-way communication with `ssh`. `qx()` only allows to receive from the child process. That said, you're probably better off using Expect and let it worry about the nitty gritty parent-child communication details.	[reply] [d/l] [select]
