iTerm2 Multiple sessions script

010--readme.md

Multiple sessions with iTerm2

Save the file as ~/Library/Application Support/iTerm2/Scripts/ssh_multiple.scpt

Restart iTerm and go to scripts menu and select the script.

Once opoened, a prompt to select a txt file will open. Select a new-line separated .txt file, containing the hostnames of the servers you want to connect simultaneously.

eg:

example.com
example.org
example.net

In iTerm2, hit ⌘Command + ⇧Shift + I to activate "Keybord input to multiple sessions".

Whatever you type, will be typed to all open tabs. Useful to run interactive apps (like sending multiple keystrokes to vim etc)
