I have found that the easiest way to get your feet wet with the grep command is to just dive right in and use some real-world examples. If for whatever reason, it is not installed on your system, you can easily install it via your package manager as shown. Grep is a powerful file pattern searcher that comes equipped on every distribution of Linux. Let’s say we want to copy all the files from a directory, without descending into the subdirectories, while processing the filenames.Īn extra requirement is that we need to perform this operation from an arbitrary location (therefore, we need full paths).įor simplicity, we use files without spaces/wildcards for covering those cases, sophisticated handling is required.Have you ever been confronted with the task of looking for a particular string or pattern in a file, yet have no idea where to start looking? Well then, here is grep to the rescue! Introduction to the problem, and the find tool Introduction to the problem, and the find tool.in the new section I don’t explain in detail the concepts already explained in the old one.the concepts not needed with the new approach are interesting to know regardless.I’ve kept both sections, for two reasons: Note that I’ve been notified by a reader of the ls parameter -A, which simplifies the logic. This post is about the research I’ve done as usual, it’s an exercise in extensive usage of the available tools. I wasn’t fully convinced it was the best choice, so I checked out what’s the ls equivalent. I wanted to tweak a script of mine it included the conventional find -maxdepth 1 -type f.
