Linux: Find files on your computer with find

A standard Linux system has an incredible amount of files installed. Looking for a file location can be a painful task to do though a file browser.

Fortunately, there is a nifty command line available by default on any Linux distribution: find.

find can virtually find anything on your computer and comes with a lot of options. This tutorial will introduce a basic use of it and show how you can search your filesystem for file names matching a name pattern.

On Debian based distros, find is part of the package findutils. find allow one to search for files on a filesystem based on different condition, creation date, modified date, file size, file type, permissions, name ....

In this tutorial, I will be focused on finding files/directories based on their name, in order to explain in more depth the syntax of find, I will also show how you can narrow down your search by adding condition on size and file modification time.

This will suit most searches, if you need more details, I would recommend looking at the find's manpage.

1. Find basis

The default syntax of find is as such:

find [path] [expression]

where path is the path used as root for searching pattern and expression the expression we want the file to match.

2. Finding a file based on filename

Let say for instance you want to find all .avi files in users home directories. Search files can be found with the following command:

# find /home -name '*.avi'

If you want to search for *.mpg and *.avi files, you will use the following:

find /home -name '*.mpg' -o -name '*.avi'

Case insensitive searches can be achieved by using the -iname switch:

find /home -iname '*.mpg' -o -iname '*.avi'

3. Adding some more criterias

Those kind of searches might returns far too many results, making it hard to find waht you were looking for in the first place.

Fortunately, you can narrow down the search by adding criteria such as the file size and the file modification date.

Let'search for .avi files bigger than 700M. This can be done with:

find /home/ -name '*.avi' -a -size +700M

Now, let's find the same subset of files that were modified less than 15 days ago:

find /home/ -name '*.avi' -a -size +700M -mtime -15

4. Adding some actions

Grand, we can now find files based on a subset of criteria. What would be even better is to apply some actions on those files. Action can be done with the use of -exec switch.
We can now find .avi file that are newer that 15 days, in this example, we are going to move those file to another location: /my/new/movies . I consider that this directory already exist on your system.
Moving .avi files bigger than 700M and younger than 15 days to /my/new/movies can be done with:

find /home/ -name '*.avi' -a -size +700M -mtime -15 -exec mv '{}' /my/new/movies/ \;

Mind the use of '{}' and \; (there is a space before \;).
'{}' matches the file that was found, while \; terminate the exec statement.

5. Conclusion

find is a powerful tool with an extensive set of statement. This article only covered a small subset of available features. For more information on the find command I recommend checking out its man page.

Clean Up Ubuntu Grub Boot Menu After Upgrades

To remove GRUB entries, we'll need to edit the file /boot/grub/menu.lst. You can do this by using Alt+F2 and then typing in the following command:

gksu gedit /boot/grub/menu.lst

Now that we've got the file open, scroll down to the bottom of the file where it says "End Default Options", and you'll find all the menu entries for the various kernels in here. You can just select and delete the ones you want.

Save the file, and then the next time you boot up you'll see a much nicer set of options.

Comments:

No need to delete those lines to simplify the GRUB menu. The easier way to keep only newest lines is to open the menu.lst (gksu gedit /boot/grub/menu.lst), find "#howmany=all" and change it to "#howmany=1″. Then run "sudo update-grub" to update changes. Next time, only newest kernel lines will be shown.

Unix Filesystem

Windows users who dive into *nix without first researching the operating system are in for quite a shock. The complete lack of a C:\ drive can send Windows switchers into a tailspin. Thankfully, IBM developerWorks does an excellent job of explaining the structure and organization of the *nix filesystem and the perks of the *nix naming conventions.

Many directories in the UNIX file system serve a special purpose, and certain directories are named per long-standing convention. In this installment of the "Speaking UNIX" series, discover where UNIX stores important files.

Searching for Files in Linux (or Windows)

Anyone with Windows experience who is new to UNIX/Linux/CygWin pretty quickly figures out that the LS command in UNIX is the equivalent of the DIR command in Windows. At least, it is equivalent up to a point. Issuing the DIR command in Windows (with no arguments) will display the contents of the current folder. Issuing the LS command in UNIX with no arguments will do the same. After that, however, the similarities end. Say, for example, you’re searching for a file called “debug.log” that you know to be in a subfolder, or sub-subfolder, of the current directory. In Windows, the command “DIR /S debug.log” will do the job nicely. The “/S” switch tells the DIR command to recurse through every subdirectory, while the “debug.log” argument tells the DIR command what file(s) to look for.

In UNIX, however, the tool for that job is the FIND command, not the LS command. Specifically, in this case, it would be “find . -name debug.log”. The first argument after the word find — the lone period — tells the FIND command where to start looking. (As with Windows, a single period means the current directory.) The “-name” switch, together with its argument of “debug.log”, establishes a criterion for the name of the files to be found. There are dozens of other criteria available, which can be used separately or in combination. These criteria, or “tests”, include being able to test on the age of the file, the type of file, the size of the file, and attribute flags of the file. Other options available with the FIND command include actions that can be taken against the found files, such as deleting the file(s) found, or executing an arbitrary command and passing it the name of each file found.

Tip #1: Use “MAN FIND” to read all about the find command. Be sure to scroll all the way to the bottom to see a number of examples.

Tip #2: If you have trouble coming up with a combination of criteria to do what you expect, then take advantage of the -D switch to turn on one or more of the debug options. This gets the FIND command to “show its work” so you can see what it’s thinking, and how it’s interpreting the switches.

Tip #3: As you can see, the UNIX FIND command is significantly more powerful than the Windows DIR command. CygWin, the Linux emulator for Windows, allows the FIND command to be used in Windows — to search Windows drives. (See our previous articles for how to get started with CygWin.)
