Find Files Modified On A Specific Day

In today’s article, we’re going to do exactly what the title says, we’re going to find files modified on a specific day. Imagine that! We’re doing what it says in the title! I dunno why I write the things I do. But, I do have quite a few people reading, and hardly any of ’em complain!

So, why would you want to do this? Well, let’s say Big Bad John logged into your system on Friday. He was fired for drinking at lunch, but still had access to the system for another hour before security got around to hauling his butt out of the building.

Wouldn’t you like to know what files were changed on his computer that day, just to see if he’d done anything malicious? You might also have some weird system errors and want to know what files have changed today so that you can narrow down your search for the culprit. There are all sorts of reasons why you might want to know how to find files modified on a specific day.

We’re going to be using a simple command, and just one command. We’ll be using the ‘find’ function. There are surely other ways to do this, but we’ll use the find command. It works and it means you have a relatively short article.

How To: Find Files Modified On A Specific Day:

This article requires an open terminal, like many other articles on this site. If you don’t know how to open the terminal, you can do so with your keyboard – just press CTRL + ALT + T and your default terminal should open.

With your terminal now open, let’s say you want to find files edited on the day this article is published. To do that, you’d run this command:

For the sake of simplicity, the format is YYYY-MM-DD. You could use other date formats that are recognized by the system, but we’ll just stick to this date format as it’s nice and easy.

Now, you can also adjust your ‘maxdepth‘ value. If it’s a 1, it will dig down one directory deep. So, if you’re in your home directory, it’ll dig into ~/Downloads, ~/Pictures, ~/Documents, etc… If you change it to 2, it’ll dig into the sub-directories, like ~/Downloads/foo and ~/Documents/bar.

If you want to find files modified on a specific day, simply change the date in the command and start searching. It’s handy if you edited a file and can’t recall which file it was you edited. The command can be used for all sorts of things like that. Good luck!

Closure:

There you go… You have another article and this one teaches you how to find files modified on a specific day. It’s a short article with just one command. There’s no reason to pad the article further. It’s just the one command. Thanks for reading!

Let’s Install And Use ‘locate’

Today, we’re going to learn to install and use locate and we’ll even cover some basic usage. If you’re unfamiliar with locate, it does exactly what you’d expect – it helps you locate files on your computer. Read on for a basic understanding.

The locate command is a terminal-based command, a text way to find files on your computer. It can be a pretty useful command – with some advanced usage – but we’ll just cover some basics.

The locate command is actually installed by installing ‘mlocate‘. So, let’s just get that out of the way. Depending on the distro you use, it’ll likely be in your default repositories and you can install it much like you’d install any other software. For example, in a distro that uses apt you’d install it with:

You may have it installed by default. You can check that with:

If that spits out a version and some version information, you’ve already got it installed and there’s no need to install it.

Anyhow, with that accomplished, let’s learn a bit about how to …

Use Locate:

This article requires an open terminal, like many other articles on this site. If you don’t know how to open the terminal, you can do so with your keyboard – just press CTRL + ALT + T and your default terminal should open.

Of course, you’d have had to open the terminal in the preamble, but I  might as well tell you again. With the terminal open, you can check the man page for locate. You’ll see it does exactly what you’d expect it to do:

locate – find files by name

To use the locate command, it’s quite simple. It’s ‘locate <flags> <file_name>‘ and really quite simple. It does what you tell it to do, nice and easy. 

For example, it may return a lot of results:

Or it can be quite targeted:

However, it needs a database to work from. If you’ve just installed the mlocate package, you’ll need to update the database. Hmm… I probably could have mentioned this sooner. Oh well… You’ll find it if you need it. It pays to read all the words, folks!

To update said database, it’s this command:

Now, there are a couple of useful flags. We’ll cover a few. You can just return a number of how many files match the description with the -c flag:

You can limit the number of responses with ‘-n <number>‘ easily enough:

The locate command defaults to being case-sensitive, but you can change that behavior with the -i flag:

Finally, you can check the database statistics with this command:

While there are other options for the locate command, including using it with other commands, those are the options I find myself using more often than not. I suspect those will be the most often used options when you too make use of the locate command. Be sure to check ‘man locate‘ for more information.

Closure:

See? It’s a quick and easy article about how to use locate to find files on your Linux computer. It’s not terribly difficult and it’s a handy command to have learned. As mentioned, the man page has even more options for you to use the locate command. Feel free to check ’em out.
