Let's say I entered a bunch of commands one after another: rm blah.txt pwd ls cd .. cd blah pwd If I want to get "rm blah.txt" to appear again without typing the whole thing again, I can press up 6 times. But is there a faster way? Can filter my command history based on some text? Intuitively, I would like to just type in r and then press up to search through my command history for only commands that started with "r".
