You can create a shortcut with pre-defined tabs like this:
Terminal --geometry=100x40 --hide-menubar --hide-toolbars -T "Host1" -e "ssh -t root@host1" --tab -T "Host2" -e "ssh -t root@host2"
But something like that in the Command line of the shortcut editor dialog.
To have each tab have a different working directory you can do it this way:
Terminal --working-directory=$HOME/tmp --tab --working-directory=$HOME/src --tab --working-directory=$HOME/opt
Not that the first one doesn't have a
--tab before it, making it associate with the new top-level window. Then two additional tabs with different working directories.
Try to avoid using
~ expansion, as that is a shell feature that may not work in other context (such as custom launchers).
