Grep directory names12/30/2023 ![]() It looks like Silver Searcher ( ag) is the winner. Next, let’s see a comparison of time taken by some of these commands for our use case of searching the “Hello, world!” pattern across files: $ time find. Although these utilities perform faster than grep, they aren’t preinstalled in most Linux distros. I created a script file called dsearch (directory search) to do this: /bin/bash search all folders from the current folder for a foldername foldername1 find. Perfect! We can see that the tmp-hello-world file is now excluded from the result.Īlthough grep is still the most widely known search utility in Linux, there are a few good grep-alternatives, such as UniversalCodeGrep ( ucg), Silver Searcher ( ag), ack, sift, and Platinum Searcher ( pt) utilities. cmevoli with this method, grep goes through all the files and sed only scans the files matched by grep.With the find method in the other answer, find first lists all files, and then sed will scan through all the files in that directory. And it works with non-GNU versions of find and xargs. name '.ch' -print xargs grep hello /dev/null This might pick up a few names you didn't intend, because the pattern match is fuzzier (but simpler), but otherwise works. So, let’s install the ripgrep package because it isn’t preinstalled in most Linux distros, and put it into action for search: $ apt-get update & apt-get -y install ripgrep If you don't have obstreperous names (with spaces etc), you can use: find. That’s one scenario where the ripgrep utility can help us. So, we can infer that the grep command doesn’t exclude the file entries in the. We can see that the last entry in the output is for the tmp-hello-world file. ![]() In continuation, let’s use the grep command to search for the pattern “Hello, world!” across files: $ grep -Rl "Hello, world!". Next, let’s create the output directory and add the tmp-hello-world file containing the “Hello, world!” pattern: $ mkdir -p output echo "Hello, world!" > output/tmp-hello-world For such scenarios, ripgrep is another helpful utility in our toolkit.įirst, let’s take a look at one of the entries in the. The same applies when trying to find files containing a text pattern. While working with a git repository, we usually want to exclude the files added in.
