Write into multiple ssh screens at once
Sometimes I need to write commands to a handful of SSH sessions at once. I use putty terminal from Windows and did not find anything useful. So I let myself inspired by Rusty Klophaus’s pecho and wrote a Perl script, which is little bit more gentle to the escape sequences and than a small bash script which will nicely open multiple SSH sessions to given list of hosts. The nice think is that this works almost everywhere and does not need more than one standard Perl library on the writer side (on CentOS just run yum install perl-TermReadKey).
