If you are using a Desktop interface like KDE or GNOME, you might have an easier time counting files in directories. $ tree /home/userĩ388 directories, 32633 files Counting Files using Graphical User Interface $ tree -a įor example, if we count files and directories in your “/home” directory, you will be able to see that there is a difference because multiple hidden files are present. In Linux, the grep command is used to search for text patterns in files. In order to count hidden files using tree, you have to execute “tree” and append the “-a” option for “all”, followed by the directory to be analyzed. In some cases, you may want to count hidden files on your system.īy default, whether you are using the “tree”, “find” or “ls” commands, hidden files won’t be printed in the terminal output. $ sudo yum install tree (for CentOS/RHEL hosts) Counting hidden files with tree $ sudo apt-get install tree (for Ubunbu/Debian hosts) If you are having a “tree : command not found” or “tree : no such file or directory”, you will have to install it using sudo privileges on your system. The “tree” command is not installed on all hosts by default. When it finds a match, it prints the line with the result.As you can see, the number of files and directories is available at the bottom of the tree command.

In case you want to limit the grep output to a particular number of lines, you can do that using the -m command-line option. ![]() grep -A to add number of lines to display after a match How to limit grep output to a particular number of lines.grep -m2 Limit grep Output to a Fixed Number of Lines.grep -n to Display Line Numbers with grep Matches.By default, grep only outputs files with the first matching value. For example, if you type grep in a text file, you can see that there are a total of two lines containing the pattern you entered. By specifying a pattern in a file, it can output a number of lines with the same pattern. ![]()
