no more grep: rak
I’m a big big fan for grep and sure couldn’t program without it. Especially if you are working in an existing project or software and don’t have a complete picture yet or the software is a confusing patchwork, grep is sometimes my only tool besides the editor. grepping in an rails app can be necessary too, sometimes, and with rak there’s an alternative for the lazy among us. The only features over grep are highlighting the pattern and skipping the files/directories for version controlling.
