This last week was my first on-call rotation at work. With each issue I was working on, I would usually find myself looking at some dashboard of hostnames and metrics. When I found the suspect machine, I would copy the hostname, open a new terminal, and type
ssh hostname. Pretty straightforward, but I still got tired of doing the same repeative actions ad nauseam. I turned to one of my co-workers and said "wouldn't it be great if I could highlight a hostname, press a button, and have a new shell opened on that host?"
It turns out I can. I use Ubuntu and the i3 window manager at work. X11 has two clipboards: the primary clipboard contains the last selected text and the secondary clipboard is usually filled after you press ctrl+c. I found a utility called xclip which gives me the contents of either in a shell script. Now I have a script, sshclip, which will launch a terminal and connect to whatever is in my primary clipboard. I bound the script to super+g for go-to (really it was the only free key close to ctrl+c).
The script attempts to strip off any surrounding garbage or port numbers from the hostname, so I don't even need to be picky about what I select.
sshclip is available in my bin/ git repo.
