It’s fun to learn about new command line tools from coworkers. Here are two.
- rlwrap can be used to wrap anything in a realine command history. It’s useful to preserve command history, including the commands typed in remote ssh sessions. Just wrap ssh in rlwrap.
- ag, the silver searcher, is a super-fast recursive grep tool. I enjoy using it, and am pleased at how quickly it returns search results on my source code trees.
