krejoinstack is an application that uses KDE Konsole terminals to connect and open terminal connections to multiple systems at the same time, making possible to debug or working on a system automatically loggin into jump hosts and target hosts and them running commands (like opening a log file) on each of then.

Using the Konsole graphical terminal has some advantages:

• Unlimited scrollback (needs konsole configuration);
• No need for wrist painfull shortcuts ('Ctrl+A + Command' to move between screens);
• Easier search with regular expression and other facilities provided by konsole;
• Session bell on window activity or silence. Leave commands running and get notified when something changes or stops;
• Scrollback reset clears any previous printed message allowing to search, focus on what you actually is searching;
• Many other features and desktop integration;

1. Install konsole in you desktop (tested on Ubuntu systems only):

snap install krejoinstack
