Checking file sizes
H2: When it comes to managing space on your Linux system, it is essential to have knowledge about file sizes. Fortunately, there are several simple and efficient ways to check it.
H3: In the terminal with the "ls" command
A quick and easy way to check the size of a file in Linux it is using the terminal and the "ls" command. Simply open a terminal window and navigate to the location of the file you want to analyze. Then, enter the following command:
ls -lh file_name
This command will show you detailed information about the file , including its size in a human-readable scale (for example, kilobytes or megabytes).
H3: Using the NCDU tool in the terminal
Another useful option to quickly verify the size of the files is to use the NCDU (NCurses Disk Usage) tool in the terminal. This tool allows you to browse your directories and graphically view how much space different files and folders take up.
To use NCDU, simply install it if you don&;#39;t have it previously installed using your favorite package manager. Once installed, run `ncdu` followed by the name of the directory you want to scan. You will soon see a list sorted by size that will help you identify which files are taking up the most space on your hard drive.
These are just a few simple but effective ways to quickly check file sizes in Linux ! In the following sections we will explore how to view them and even find those that are too large. Keep reading for
In the terminal with the "ls" command
In the terminal with the "ls" command, we can get information about the files and directories in Linux. This command is one of the most basic and useful commands that you should know if you are working in a command line environment.
Running the "ls" command without any arguments will display a list of all the files and directories in the current directory. In addition to the name of the file or directory, information such as permissions, size, modification date, and owner is also displayed.
To view only the size of the files instead of all the detailed information, you can use the "-l" option together with the "ls" command. This will show you a list sorted by size in human-readable format (KB, MB).
If you want to search for specific files within a directory, you can use patterns or wildcards with the "ls" command. For example, if you want to see only files that have a ".txt" extension, you can run the following command: ls *.txt
Using the "ls" command can be very practical when you need to have a Quick overview of the content within a given directory. However, if you need to get more details about each file or directory individually, you may want to consider other tools such as NCDU or stat.
Remember that mastering basic functionalities like this will allow you to work efficiently in the terminal and get the most out of your Linux experience. So don&;#39;t hesitate to explore all the options available through the "ls" command and discover how it makes your daily tasks easier!
Using the NCDU tool in the terminal
Using the tool NCDU in the terminal is a great way to visualize file sizes in Linux. This tool allows us to explore our directories and see how much space different files and folders are taking up.
Once NCDU is installed, we can run it from the terminal by simply typing "ncdu" followed by the directory we want to analyze. The tool will scan all the files and subdirectories within the specified directory and show us a detailed breakdown of the space used by each one.
NCDU&;#39;s interface is very intuitive and easy to use. We can navigate through the different folders using the arrow keys, and when selecting a folder or file, we will get detailed information about its exact size.
In addition, NCDU also presents interactive graphs that clearly show what percentage of the space total is being occupied by each file or folder. This helps us quickly identify those elements that are consuming the most space on our system.
Using the NCDU tool in the terminal is an efficient and practical way to obtain accurate information about file sizes in Linux . It gives us a clear view of hard drive usage and can even help us identify those files or folders that we could delete to free up additional space on our machine.
File size display
Sometimes it is useful to be able to see the size of files on our Linux system. Fortunately, there are several ways to do this. A simple and quick way is to use the "stat" command in the terminal. You just need to type "stat" followed by the name of the file you want to check and press Enter. This will show you detailed information about the file, including its size.
If you prefer a more visual option, you can also use your favorite file manager to view file sizes. For example, in Nautilus or Thunar you simply have to select a file and look at the properties to find its size.
In general, having access to this information can be very useful when we want to know how much space our files are taking up. files on disk or if we are trying to identify what is consuming a large amount of space.
Remember that keeping an eye on the size of your files can help you optimize your Linux operating system and ensure that you have enough space available for your daily needs.
So you now know how to view file sizes both from the terminal and from your favorite file manager. Don&;#39;t waste time looking for where all that space went!
Using the "stat" command in the terminal
Using the "stat" command in the terminal, we can get detailed information about a file on Linux. This command shows us data such as the size of the file, the date of creation and modification, access permissions and much more.
To use this command, we simply open the terminal and type "stat" followed by full name or path of the file we want to inspect. Once the Enter key is pressed, all the relevant information about that file will be displayed.
An advantage of using the "stat" command is that we will not only get the total size of the file, but also additional details such as the exact dates of creation and modification. This can be useful to know when an edit was last made to a specific file.
Also, thanks to its simple and straightforward interface, we can easily use this command to get updated information instantly without having to than navigating through different menus or graphical interfaces.
The "stat" command is a powerful tool for viewing detailed information about files in Linux. Whether we need to know precise dimensions or details related to dates and access permissions, this feature is invaluable for advanced Linux users. So don&;#39;t hesitate to try it yourself!
In the file manager
Another way to view file sizes in Linux is to through the file manager. This can be especially useful if you prefer a friendlier graphical interface.
In most file managers, such as Nautilus or Dolphin, you can quickly see the size of a file by simply hovering over it and reading the information that appears in a small pop-up window. This information includes not only the file size, but also other relevant details.
In addition, many managers have additional functions to help you organize your files according to their size. For example, you can sort them by size to easily identify those that take up the most space on your system. It is also possible to filter files by specific size range using advanced options within the manager.
Using the file manager can be beneficial when you want to have a quick and easy overview of the size of your files without need to use commands in terminal. It is a convenient option for those users who feel more comfortable with intuitive graphical interfaces.
Remember that although this option offers some visual comfort, it is still important to know the tools available from the terminal as they give you greater flexibility and control over your Linux system.
Searching for large files
Searching for large files can be a challenging task in the Linux operating system. Fortunately, there are several tools and commands that can make this search easier. One option is to use the "du" command in the terminal. This command displays the size of files and directories in a user-readable format.
To use this command, simply open the terminal and navigate to the directory you want to scan. Then, enter "du -h" followed by the name of the directory or file you want to inspect. The result will show a detailed list with the sizes of all files and subdirectories within the specified directory.
Another useful tool is "tree", which you can also use from the terminal. Like "du", it allows you to view the folder structure and their corresponding sizes. Simply run the command "tree -h" followed by the parent directory name to get a hierarchical graphical representation.
These tools are especially useful when you need to free up space on your hard drive or find specific large files quickly. With just a few commands, you can easily identify which files or folders are taking up the most space on your Linux system.

Find files that exceed the specified size limit
Sometimes, we need to find those giant files that are taking up valuable space on our system. Fortunately, in Linux there are simple and effective ways to do this. One option is to use the "find" command in the terminal.
With the "find" command, we can search for files based on different criteria, such as the file name or its size. To search for files that exceed a specific size limit, simply use the "-size" option followed by the desired value and a unit (such as K for kilobytes or M for megabytes).
For example, If we want to find all the files that are larger than 100 megabytes in our personal folder, we will write the following:
find ~ -type f -size +100M
This will show us a list with the names and locations of the files found. If we want to perform a more precise search within a specific path, we will simply replace "~" with the desired path.
It is important to be careful when setting the size limit to avoid accidentally excluding some important files or including too many results. Always remember to check your results before taking any action on them.
Now you are ready to find those big, heavy hidden files! Free up space on your hard drive!
How to use the "find" command in the terminal to search for files
The "find" command is a very useful and powerful tool that allows us allows you to search for specific files on our Linux system. With this command, we can perform searches based on different criteria such as the name of the file, its size or even its modification date.
To start using the "find" command, we simply have to open the terminal and write the following basic format:
find path -options
In this case, "path" specifies where we want start our search and the options are the criteria that we will use to filter the results. For example, if we wanted to find all files with the extension ".txt" within the "/home/user" directory, we could use the following command:
find /home/ user -name "*.txt"
In addition to filtering by name, we can also search for files by size using the "-size" options. For example, if we wanted to find all files larger than 1 megabyte within a specific directory, we can use the following command:
find path -size +1M
It is also possible to combine different filters to further refine our searches. We can set maximum or minimum size limits along with other criteria such as file type or modification date.
Remember that this is just an introduction to using the "find" command. You can consult its man page to know all its options and customize your searches according to your needs.
