![]() ![]() There are many supported types, but for this blog post, we are concerned with only directories ( d) and files ( f).įor more information on other tests, check out the find command's documentation in the Linux Manual Page. Type ( -type) - Match for a specific type. Size ( -size) - Match if the size of a directory/file is greater than ( + prefix), less than ( - prefix) or equal (no prefix) to the argument specified for -size. ![]() Use -iregex for the case-insensitive variant. Regular Expression ( -regex) - Match if the path of a directory/file fulfills the regular expression passed as the argument specified for -regex. 000 indicates no permissions, and 777 indicates full permissions. Permissions ( -perm) - Match if the permissions (read/write/execute for owner/group/everyone) of a directory/file equals the argument specified for -perm. Use -ipath for the case-insensitive variant. Path ( -path) - Match if a directory/file belongs within the path (a glob pattern) passed as the argument specified for -path. Use -iname for the case-insensitive variant.Įmpty ( -empty) - Match if a directory is empty or a file has no content. Name ( -name) - Match if the name of a directory/file equals the name (a glob pattern) passed as the argument specified for -name. Note: Angle brackets indicate required arguments, whereas square brackets indicate optional arguments.Īn expression describes how to identify a match via tests, which use certain properties of directories/files to determine which directory/file satisfies the defined conditions: To recursively list all of the directories and files (including those hidden) within the current directory: When a file or directory matches search criteria (based on the options provided to the find command), the find command outputs the matched directories and files by their path relative to the given starting point/s. The find command, as its name implies, recursively finds directories and files located within a specified list of directory paths. To demonstrate the find and grep commands, we will search for directories and files within a downloaded copy of one of GitHub's most popular repositories, facebook/react. How to interpret and construct your own glob patterns. ![]() How to locate a text string via the grep command within a file. ![]() How to locate folders and files via the find command within a folder hierarchy. Both the find and grep commands are considered as some of the most essential building blocks in bash scripting! Knowing how to use them allows you to integrate them into your continuous integration (CI) pipeline to automate search tasks. Instead, the command prints the search results to standard output ( stdout) displayed within the terminal. With a single-line command, you avoid interacting with the interface of the computer's file explorer. Operating systems based on the UNIX kernel provide the find and grep command-line utilities to search for files/folders and text within a file respectively via pattern matching. Additionally, a computer's file explorer, such as Mac's Finder or Ubuntu's Nautilus, slows down when loading and displaying folders and files within large external hard-drives, thumb drives or SD cards filled (or nearly filled) to maximum capacity. If you forget to close the folders after exploring them, then these opened folders accumulate over time and obstruct subsequent searches by cluttering the screen. Navigating the workspace and rummaging through every folder (double-clicking each one) to find a single folder or file becomes repetitive and directs attention away from your work. If you work within a disorganized workspace with deeply nested folders and try locating a specific folder, file or code snippet, then your productivity suffers from the constant distraction of manually searching through the workspace. ![]()
