![]() ![]() Output main.go:120:func main() Example Command grep -R "apples". The above command will try to find a string “func main()” in all the files in a particular directory and also in the subdirectories as well. In the above command replace the “word” placeholder withįor that, we make use of the command shown below − grep -rni "func main()" * Now, let’s consider a case where we want to find a particular pattern in all the files in a particular directory, say dir1. Although most file managers bring built-in search features, the find command is one of the best terminal tools for casual users to system administrators. R : stands for recurse, would go into subdirectories as well. 4 min by Arindam 6 months ago 1 956 views This article is part of the Linux command series and explains various examples of find commands in Linux to find files and directories. v : It prints out all the lines that do not match the pattern n : Display the matched lines and their line numbers. While there are plenty of different options available to us, some of the most used are − -c : It lists only a count of the lines that match a pattern Normally, the pattern that we are trying to search in the file is referred to as the regular expression. It is one of the most used Linux utility commands to display the lines that contain the pattern that we are trying to search. The grep command in Linux is used to filter searches in a file for a particular pattern of characters. ![]() In our case, we only need to match files.In order to be able to find all files with names containing a string in Linux command line, we will make use of the grep command, and at first we must understand what a grep command is and how to use it on Linux. ![]() The -type test is used to filter the type of the match. mozilla/firefox/esr/extension-preferences.json mozilla/firefox/esr/shield-preference-experiments.json Through the following examples and explanations, you’ll learn how to use it. However, we can if we want to search for files by extension, we can simply use -name or -iname: $ find -type f -iname "*.json" So all you really need to know is how to use the command effectively. * at the beginning of the regex is used to print the path of the file.

You can use the find command to search for a file or directory on your file system. The – regex test specifies a pattern that is used to match all files that contain zsh in its filename.

For that reason, we can use the -iregex or – regex test: $ find -regex ".*\(zsh\|bash\)rc" Sometimes, we might want to search for files based on a pattern. The -iname test turns off case sensitivity, as opposed to the -name test, which retains case sensitivity. We’ll specify it using the -iname test: $ find -iname ".zshrc" The grep command from Linux is one of the powerful commands to find files containing some text, but when you use grep, it not only print the file name but. When we run the find command without any options, it will list all the files and directories in the current directory.
