After a lengthy JIRA tip, I’m about to blog a Keyboard Ninja tip for users who do a lot of Ctrl + R thingy to navigate Bash history.
This came up when I didn’t want to use a session manager like PAC but rely on Bash history. I have a server IP address and SSH access.
So, instead of doing just ssh -v firstname.lastname@example.org thing, I do this:
ssh -v email@example.com #jirauat
Those who are familiar with scripting know this: Whatever you type after the hash sign won’t effect, because Bash interprets that as a comment. However, Bash history records the complete line.
Later, I don’t have to remember the IP address, but, when I type Ctrl + R followed by jirauat, it comes up quickly. Just hit Enter!
(reverse-i-search)`jiraua': ssh -v firstname.lastname@example.org #jirauat
And that’s how you easily save few keystrokes plus an additional minute without having to recall numbers.
