The Linux find command is very powerful. It can search the entire filesystem to find files and directories according to the search criteria you specify.

Besides using the find command to locate files, you can also use it to execute other Linux commands grep , mv , rm , etc. If you just want to see some examples and skip the reading, here are a little more than thirty find command examples to get you started. Almost every command is followed by a short description to explain the command; others are described more fully at the URLs shown:.

If you know of any more good find commands to share, please leave a note in the Comments section below. If it finds the file, it prints the location to the screen. On Linux systems and modern Unix system you no longer need the -print option at the end of the find command, so you can issue it like this:. The -type f option here tells the find command to return only files. If you don't care about that, just leave the -type f option off your command. To search in the current directory — and all subdirectories — just use the.

The filename can end with any other combination of characters. It will match filenames such as Chapter , Chapter1 , Chapter1. These file locations are then printed to the screen:. Every option you just saw for finding files can also be used on directories. Just replace the -f option with a -d option. For instance, to find all directories named build under the current directory, use this command:. To find all files that don't match a filename pattern, use the -not argument of the find command, like this:.

This next command shows how to find all files beneath the current directory that end with the extension. The -l argument to the grep command tells it to just print the name of the file where a match is found, instead of printing all the matches themselves:.

Those last few characters are required any time you want to exec a command on the files that are found. I find it helpful to think of them as a placeholder for each file that is found.

This next example is similar, but here I use the -i argument to the grep command, telling it to ignore the case of the characters string , so it will find files that contain string , String , STRING , etc.

When these files are found, their permission is changed to mode rw-r--r This find command searches through the htdocs and cgi-bin directories for files that end with the extension. When these files are found, their permission is changed to mode rwxr-xr-x. This example shows that the find command can easily search through multiple sub-directories htdocs , cgi-bin at one time:.

From time to time I run the find command with the ls command so I can get detailed information about files the find command locates. That's nice, but what if I want to see the last modification time of these files, or their filesize? No problem, I just add the ls -ld command to my find command, like this:.

The "-l" flag of the ls command tells ls to give me a "long listing" of each file, while the -d flag is extremely useful in this case; it tells ls to give me the same output for a directory. Normally if you use the ls command on a directory, ls will list the contents of the directory, but if you use the -d option, you'll get one line of information, as shown above. Be very careful with these next two commands. If you type them in wrong, or make the wrong assumptions about what you're searching for, you can delete a lot of files very fast.

Make sure you have backups and all that, you have been warned. Here's how to find all files beneath the current directory that begin with the letters 'Foo' and delete them. This one is even more dangerous. It finds all directories named CVS, and deletes them and their contents. Just like the previous command, be very careful with this command, it is dangerous! For example, if you want to search for all files and directories named foo , FOO , or any other combination of uppercase and lowercase characters beneath the current directory, use this command:.

To find all files and directories that have been modified in the last seven days, use this find command:. The locate command keeps filenames in a database, and can find them very fast.

Last updated: October 18, The remaining sections on this page describe more fully the commands just shown.

For instance, to find all directories named build under the current directory, use this command: find. The -l argument to the grep command tells it to just print the name of the file where a match is found, instead of printing all the matches themselves: find. No problem, I just add the ls -ld command to my find command, like this: find. Find and delete Be very careful with these next two commands.

In this Linux quick tip we will be discussing how to find empty directories and how to delete them. We will also examine how to find empty files zero size and how to act on them as well. Using the find command and a few options we can easily find empty directories.

Contents Why use the terminal? The traditional Unix environment is a CLI command line interface , where you type commands to tell the computer what to do. That is faster and more powerful, but requires finding out what the commands are.

Perforce When no file patterns are specified on the command line, p4 sync copies a particular depot file only if it meets all of the following criteria:. The file must be visible through the client view ;. It must not already be opened by p4 edit , p4 delete , p4 add , or p4 integrate ;.

One of the most common tasks that find is used for is locating files that can be deleted. This might include:. This example concentrates on the actual deletion task rather than on sophisticated ways of locating the files that need to be deleted. This approach works and in fact would have worked in Version 7 Unix in However, there are a number of problems with this approach. All this is quite inefficient. The commands above are much more efficient than the first attempt. However, there is a problem with them. The shell has a maximum command length which is imposed by the operating system the actual limit varies between systems. This means that while the command expansion technique will usually work, it will suddenly fail when there are lots of files to delete.

Quick Answer:

In most cases the means we use to delete a file from our computers such as using Delete key, Trash files or rm command, which do not permanently and securely remove the file from the hard disk or any storage media. The file is simply hidden from users and it resides somewhere on the hard disk. It can be recovered by data thieves, law enforcement or other threats. Assuming a file contains classified or secret content such as usernames and passwords of a security system, an attacker with the necessary knowledge and skills can easily recover a deleted copy of the file and access these user credentials and you can probably guess the aftermath of such as scenario. In this article, we will explain a number of command line tools for permanently and securely deleting files in Linux.

The command is also available in the EFI shell. The rm command removes references to objects from the filesystem using the unlink system call, where those objects might have had multiple references for example, a file with two different names , and the objects themselves are discarded only when all references have been removed and no programs still have open handles to the objects. This allows for scenarios where a program can open a file, immediately remove it from the filesystem, and then use it for temporary space, knowing that the file's space will be reclaimed after the program exits, even if it exits by crashing. The command generally does not destroy file data, since its purpose is really merely to unlink references, and the filesystem space freed may still contain leftover data from the removed file.
