Search your bash history
Ever wanted to search your bash history for a specific command? Worry no more, reverse-i-search is there to help. If you press Ctrl-R at your bash prompt, you will get the following:
Here you can type whatever you want to search and you will see that bash will present with most recent command that matches your search:
(reverse-i-search)`cat': adb logcat
If you press Enter you just execute it. If you press the arrow keys (or Home/End), you go back to the prompt with the command to edit. Ctrl-R again goes backward to previous match in your history. Ctrl-G exits the search and returns to an empty prompt.
Another handy tool to know :)
