(Yeah, matching any character would be harmless in our case, but I did it for completeness' sake.) In case you want to use it as a literal dot, you'll have to "escape" it using a backslash \ before it. in regex has a special meaning too: it means "match any single character here". ^ in regex matches the beginning of the string this prevents it from matching the pattern if it doesn't occur in the beginning of the file name. Regex is an extremely powerful searching tool if you master it, and there are sites such as this which teach you about it in more depth, but note that grep is not a full-fledged regex engine and you can't do everything with it. Now the pattern itself is written in a particular syntax called regular expression, or regex for short. Notice that the pattern is quoted with single quotes ' ' to prevent the shell from interpreting the special characters inside it.Grep takes the output and filters it using the given pattern, ^\./ABC. The pipe character | redirects the output of one command to another, in this case the output of find is redirected to grep. Being aware of this is important because it means we will search for results starting with. , indicating that their path is relative to the current directory. Note that find outputs each file or directory starting with. To understand the command, let's break it down a bit:įind lists all files under the current directory and its sub-directories using it alone will just list everything there. Generally, if you want to just list them, you can do it in a terminal using: It will find all files which match the criteria.There are many ways to do it, depending on exactly what you want to do with them. Type the text which the files contain and hit the Enter key. You can specify something like "*.txt" to search for your text in text files only. To find files containing some specific text using Midnight Commander, start the app and press the following sequence on the keyboard:įill in the "File name:" section. Unlike find or grep, mc is not included by default in all Linux distros I've tried. Midnight CommanderĪnother method I often use is Midnight Commander (mc), the console file manager app. -l stands for "show the file name, not the result itself".Īs you can see, this method is less flexible than the find command.-R stands for recursive file processing.First of all, you can use only the grep tool. There are alternatives to the methods described above. If the text is found in the file, its name will be added to the output, thanks to the -l option. The -exec option calls the grep tool for each of the matching files to check their contents. type f -exec grep -l "text to find" \ XFCE4 terminal is my personal preference.įind. To find files containing specific text in Linux, do the following. Also, I find Catfish not useful and prefer classic console tools over it. However, when it comes to the terminal, you cannot use any graphical tool. You need to click on the gear icon and enable the option Search File Contents. To bypass this limitation when working in a GUI session, you can use Сatfish. Сatfish is a popular search tool. However, none of the file managers I've tried allow searching for file contents. In my favorite XFCE desktop environment, the Thunar file manager allows searching for files by typing the file name directly in the file list. If you can use the GUI, searching for files is not a problem.
