How To List Recently Changed Files (Recursive) with One Command

Ubuntu 19

In this article, we will explore how to list all recently changed files recursively using just a single command. This can be particularly useful for system administrators, developers, or anyone who needs to monitor file changes within a specific directory.

Quick Answer

To list recently changed files recursively with one command, you can use the find command in Unix and Linux systems. Simply use the command find . -type f -mtime -7 -exec ls -l {} \; to list all files modified within the last 7 days.

Understanding the Basics

Before diving into the specific commands, let’s understand what we mean by “recently changed files” and “recursive”.

Recently changed files refer to files that have been modified within a certain timeframe. This could be within the last few minutes, hours, days, or weeks.

Recursive means that the command will not only look at the files in the specified directory but also delve into all its subdirectories.

Now, let’s explore how to achieve this using one command.

Using the find Command

One of the most common ways to list recently changed files recursively is by using the find command. The find command in Unix and Linux systems is a very powerful tool for searching files based on various criteria.

Here’s an example of how you can use it:

find . -type f -mtime -7 -exec ls -l {} \;

Let’s break down this command:

  • find . initiates the find command in the current directory (represented by .)
  • -type f tells the command to look for files (not directories)
  • -mtime -7 specifies that we’re interested in files modified within the last 7 days
  • -exec ls -l {} \; executes the ls -l command (which lists details of files/directories) on each file found

Using the ls Command with zsh Shell

If you’re using the zsh shell, you can use a glob qualifier to find files that were modified within the last 7 days. Here’s how you can do it:

ls -l **/*(.m-7)

In this command:

  • ls -l lists files in long format, which includes additional information such as file permissions, number of links, owner, group, size, and time of last modification
  • **/* is a recursive glob that matches all files and directories in the current directory and all of its subdirectories
  • (.m-7) is a glob qualifier that matches files modified within the last 7 days

Using the find Command with stat and sort

Another approach is to use the find command along with stat and sort to list files in order of modification time:

find . -type f -mtime -7 -exec stat -lt "%Y-%m-%d %H:%M:%S" {} \; | cut -d\ -f6- | sort -r

In this command:

  • find . -type f -mtime -7 -exec stat -lt "%Y-%m-%d %H:%M:%S" {} \; finds files modified in the last 7 days and outputs the modification date and time in a specific format
  • cut -d\ -f6- extracts the file name from the output
  • sort -r sorts the output in reverse order, so the newest files are listed first

Conclusion

Listing recently changed files recursively with one command can be a powerful tool in your system administration or development toolkit. Whether you’re using the find command, the ls command with the zsh shell, or a combination of find, stat, and sort, you can quickly and efficiently keep track of file changes in your directories.

Remember to replace . with your desired directory path if you want to specify a different directory. Also, you can adjust the -7 in the commands to match the timeframe you’re interested in. For example, use -1 for files modified within the last day, -30 for the last month, and so on.

For more information on the commands used in this article, you can refer to the man pages by typing man find, man ls, man stat, or man sort in your terminal. You can also visit the GNU findutils documentation for more detailed information on the find command.

Can I use the `find` command to search for recently changed files in a specific directory?

Yes, you can use the find command to search for recently changed files in a specific directory. Simply replace . in the command with the desired directory path.

How can I specify a different timeframe for recently changed files using the `find` command?

To specify a different timeframe for recently changed files using the find command, you can adjust the -7 in the command. For example, use -1 for files modified within the last day, -30 for the last month, and so on.

Can I use the `ls` command with the `zsh` shell to list recently changed files recursively?

Yes, if you’re using the zsh shell, you can use the ls command with a glob qualifier to find files that were modified within a specific timeframe. The command ls -l **/*(.m-7) will list files modified within the last 7 days.

How can I list recently changed files in order of modification time using the `find` command?
