However, these example commands should still work and be useful for understanding how these programs work. This is to be expected, since you’re searching for files within directories that regular users typically don’t have access to. Because of this, if you’re logged into the terminal as a non- root user, some of the example commands may include Permission denied in their output. Note: To illustrate how the find and locate commands work, the example commands in this guide search for files stored under /, or the root directory. Click the following Launch an Interactive Terminal! button to open a terminal window and begin working with a Linux (Ubuntu) environment. Doing so will set you up with a secure server environment - including a non- root user with sudo privileges and a firewall configured with UFW - which you can use to build your Linux skills.Īlternatively, you can use an interactive terminal embedded on this page to experiment with the sample commands in this tutorial.

If you plan to use a remote server to follow this guide, we encourage you to first complete our Initial Server Setup guide. Note that this tutorial was validated using a Linux server running Ubuntu 20.04, but the examples given should work on a computer running any version of any Linux distribution. This can either be a virtual private server which you’ve connected to with SSH or your local machine. To follow along with this guide, you will need access to a computer running a Linux-based operating system. It will also briefly cover the locate command, which can be used to search for files in a different way. This will help you search for files on your system using a variety of filters and parameters.

For example, to find a certain file in the whole server, it would be best to use an alternative command – whereis or which: whereis perl In some rare cases, find and grep may prove not useful.

For example, the line below will only output configuration.php result: ls -la | grep configuration.php Grep can also be used to filter the results from other commands. This will display the filenames containing the word “ database”, but will not actually list the line containing it. To only list the file names containing the string you are searching but omit the line containing it, you can use the -l argument: grep -l 'database' * This will make grep look recursively ( -r option) and provide the result in a human-readable format ( -H option) for the string “ database” in all (*) files under the current working directory. If you don’t know which file contains the text, you can use: grep -r -H 'database' * The above command instructs grep to look for the string “ database” in the configuration.php file and display the containing line.

Or if you want to filter only files modified in the last 2 days, you would need to use: find. If you would like to list only directories and leave all files out of the result: find. If you are uncertain about the file name or would like to match a part of the name, you can use a wildcard pattern: find. Find is a very powerful tool and accepts various arguments allowing you to specify the exact search term (i.e search by name, by type or even by modified time).įor example, to search for a file called myFile.txt under the current folder (and all subfolders), you would need to use the following command: find. In order to search for a file location, you can use the find command. SSH provides two different commands, which can be used to accomplish this. In some cases, you would need to find the location of a given file or to search for a certain text in all files under a directory.
