In such cases, we can use '-R' option with 'ls' or 'find' command to list files recursively and then use 'wc' command to count number of files.įor example, to count number of files in current directory and all its subdirectories using 'ls' command, we can use following command − ls -Rl | grep "^-" | wc -l Sometimes, we may want to count number of files in a directory and all its subdirectories. number of files is equal to number of names displayed. The above command expands '*' wildcard to match all files in current directory and displays their names on screen. We can use shell expansion with 'echo' command to count number of files in a directory.įor example, to count number of files in current directory, we can use following command − echo * Shell expansion is a feature of Linux shell that allows us to use wildcard characters to match filenames. The above command lists all files in current directory, one per line, and then uses 'wc' command to count number of lines in output, which gives us number of files in directory. We can then use 'wc' command to count number of files.įor example, to count number of files in current directory, we can use following command − ls -1 | wc -l The 'ls' command can also be used with '-1' option to display only filenames in a directory, one per line. Method 4: Using ls command with option -1 Finally, 'wc' command is used to count number of lines in output, which gives us number of files in directory. The above command displays all files in current directory and its subdirectories in a tree-like format and then uses 'grep' command to filter out only files (not directories). We can use '-f' option with 'tree' command to display only files in a directory and then use 'wc' command to count number of files.įor example, to count number of files in current directory, we can use following command − tree -f. The 'tree' command is a useful tool for displaying contents of a directory in a tree-like format. Finally, 'wc' command is used to count number of lines in output, which gives us number of regular files in directory. The above command searches for all regular files (not directories or other types of files) in current directory (specified by '.'), and '-maxdepth 1' option tells 'find' command to search only current directory (not its subdirectories). We can use 'find' command with '-type f' option to find only regular files in a directory and then use 'wc' command to count number of files.įor example, to count number of files in current directory, we can use following command − find. The 'find' command is a powerful command-line tool used to search for files and directories in a directory hierarchy. The above command lists all files in current directory and then uses 'grep' command to filter out only regular files (not directories or other types of files). number of files in a directory is displayed in first column of output.įor example, to count number of files in current directory, we can use following command − ls -l | grep "^-" | wc -l We can use '-l' option with 'ls' command to display detailed information about files in a directory, including number of files. The 'ls' command is one of most commonly used commands in Linux to list files in a directory. Method 1: Using ls command with option -l In this article, we will discuss various methods to count number of files in Linux, along with examples. Counting number of files is an essential operation when dealing with large data sets and is also useful when cleaning up system or performing other maintenance tasks. One of most common tasks in Linux is to count number of files in a directory. Linux is a popular open-source operating system used by millions of users worldwide.
