![]() If you want to search for files and directories with four letters in their name, run: find /usr -name '?' txt at the end of their name, you can use: find /usr -name '*.txt' Since the * and ? characters are also special characters for the shell, putting them in quotes ensures that the command works correctly.Īs an example, if you have to search for all files and directories inside /usr that have a. If you want to use a wildcard character, you should keep the name/ iname parameter inside single or double quotes. There are two wildcards - the ? character represents a single unknown character, and the * character represents any number of unknown characters (including zero). The -name and -iname switches also accept “wildcards”, which are special characters that act as placeholders. If you don’t know the exact case of the item you’re looking for, you can use the -iname switch which is case insensitive: find /usr -iname news.txt If you want to find a file or directory named NEWS.txt inside the /usr directory, use the -name switch like so: find /usr -name NEWS.txt Find file linux recursive how to#In this section, we will learn how to filter items by their name. and simply use: find Finding items by their nameĪs we mentioned previously, you can filter the results of the find command using expressions. When there are no paths, the find command assumes that it should work with the current directory. If you want to list the contents of the current working directory, use a period(. If you want to list the contents of multiple directories, you can do this like so: find /usr/share /bin /usr/lib Depending upon the contents of the directory, this list can be very large! This will give you a list of files and directories, as shown in the screenshot below. For example, if you want to list the contents of the /usr/share directory, run: find /usr/share Imagine that you want to list all the directories and files for a given path. These concepts will become clearer as we go through various examples mentioned later in this article. However, you can also specify a custom action that the find command can take on the results. The default action is to print all the results. If you want to filter some of them out based on certain criteria, you can specify an expression to do so. This process continues till it has searched for all items inside the path you specified.īy default, the find command finds everything inside a directory. Again, if there are other directories inside, the find command will look inside them as well. Thus, when the find command encounters a directory inside the given path, it looks for other files and directories inside it. The find command takes a number of paths, and searches for files and directories in each path “recursively”. The basic structure of the find command is like so: find We will also illustrate its usage through various examples throughout this article. In this article, we will understand how to work with the find command. Optionally, it also allows you to take different types of actions on the results. It is highly flexible, allowing you to look for files and directories based on a variety of conditions. It is part of the “findutils” package and comes bundled with all distributions. Linux Permissions are a wide topic : we really encourage you to have a look at our complete guide on Linux Permissions if you want to learn more.The find command allows users to search for files and take actions on them. You learnt that you can achieve it using the “-R” option or by combining it with the find command. In this tutorial, you learnt how you can execute the chown command recursively on your system. Then, we executed the chown command in order to recursively change files permissions from the previous command.Īs a rule of thumb : if you are not sure of the output of a command, divide it into smaller pieces until you are sure that you won’t execute anything harmful. This point is illustrated in the previous section : we run the find command alone and we made sure it was the correct result. On Linux, executing commands such as chown, chmod or rm is definitive : there is no going back.Īs a consequence, you will have to be very careful not to execute any commands that will harm your system. As you can see, the owner of the TXT files were changed, yet none of the other files and directories were altered. ![]()
