The du command in Linux is used to show the amount of disk space used by files and directories. This article will show you how to use the du command to view the amount of disk space used by files and directories on your system.
How to check available disk space on Linux
Linux provides a few different ways to check available disk space. The df command provides a summary of the amount of free disk space on the system, broken down by partition. For a more detailed view of disk usage, the du command can be used. This command will show the size of each directory on the system, and can be used to identify which directories are using the most disk space.
How to check available inodes on Linux
Inodes are data structures on a Linux filesystem that keep track of all the files and folders stored on that filesystem. The number of inodes on a filesystem is limited, so it’s important to keep track of how many inodes are being used and how many are available.
There are a few different ways to check the number of inodes on a Linux filesystem. The first is to use the “df” command. This command will show you the amount of free space on each mounted filesystem, as well as the percentage of inodes that are in use. For example, the output of “df -i” might look like this:
Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/sda1 128128 128112 1 0% /
tmpfs 257080 1052 257028 1% /dev/shm
/dev/sdb1 128128 128112 1 0% /mnt/data
As you can see, the “/” filesystem is using 1% of its inodes, while the “/mnt/data” filesystem is using 0% of its inodes. This means that there are plenty of inodes available on both of these filesystems.
If you want to see more detailed information about inode usage, you can use the “du” command. This command will show you the size of each file and directory on the filesystem, as well as the number of inodes that each file or directory is using. For example, the output of “du -i” might look like this:
4 /etc/passwd
4 /etc/group
4 /etc/shadow
…
8 /home/user1/.bash_history
8 /home/user1/.bashrc
…
As you can see, some files and directories use more inodes than others. In general, files that are larger in size will use more inodes than smaller files. Directories also tend to use more inodes than regular files, because they store information about the files and subdirectories that they contain.
If you want to see a summary of inode usage for all files and directories on the filesystem, you can use the “du -s” command. This will show you the total number of inodes that are being used, as well as the total size of all files and directories on the filesystem. For example, the output of “du -s -i” might look like this:
1216 /home/user1
1216 total inodes used
How to check used disk space on Linux
Assuming you would like to know how to check disk space on a Linux machine:
1. Open up a terminal window. You can do this by searching for “terminal” in the start menu.
2. In the terminal, type the following command and press enter:
df -h
3. This command will give you an overview of the amount of disk space available on your machine, as well as how much is being used.
How to check free disk space on Linux
Assuming you would like a general overview of checking free disk space on Linux:
There are a few different ways to check how much free disk space is available on a Linux system. The easiest way is to use the command line tool “df”. This will show you a list of all the mounted file systems on the system and the amount of free space available on each one.
Another way to check free disk space is with the “du” command. This will show you a list of all the files and directories on the system and how much space they are taking up. You can use the “-h” option to make the output more human readable.
If you want a more graphical way to check free disk space, you can use the “baobab” tool. This is usually pre-installed on most Linux distributions. Baobab will scan your system and display a visual representation of where your disk space is being used.
How to check total disk space on Linux
There are a few ways to check your total disk space on Linux. One way is to open up a terminal and type in the command “df -h”. This will give you a list of all your mounted drives and how much space is available on each one. If you want to see a more detailed view, you can type in the command “du -sh” which will show you a breakdown of space used by each directory on your system.
Another way to check your disk space is to use the “Disk Usage Analyzer” tool that comes with most Linux distributions. This tool will give you a graphical view of your disk usage and can help you identify which directories are taking up the most space.
If you’re trying to free up some disk space, a good place to start is by removing any unnecessary files or directories. You can use the “rm” command to remove files and the “rmdir” command to remove directories. Be careful when using these commands, as they can delete important files if used incorrectly. It’s always a good idea to check the size of a directory before deleting it, just to be sure.
How to check used inodes on Linux
An inode is a data structure on a Linux file system that stores all the information about a file except its name and its actual data.
To check the number of inodes on a Linux file system, use the command:
df -i
This will show you the number of inodes used and the number of inodes available on each mounted file system.
If you see that the number of used inodes is getting close to the number of available inodes, it means that your file system is getting full and you will need to add more space.
How to check free inodes on Linux
In Linux, an inode is a data structure that stores all the information about a file except its name and its actual data. To check the number of free inodes on your system, you can use the “df” command. This command will show you the amount of free space on each partition, as well as the total number of inodes on each partition. The inode count is the second column from the left.
To see a detailed list of all the inodes on your system, you can use the “ls -i” command. This will list all the files and directories in the current directory, along with their inode number.
How to check total inodes on Linux
There are two main ways to check the number of inodes on a Linux system. The first is to use the ‘df’ command, which will show the number of inodes for each mounted filesystem. The second is to use the ‘find’ command, which will show the number of inodes for a given directory tree.
To use the ‘df’ command, simply type ‘df -i’ at the command prompt. This will show the number of inodes for each filesystem, as well as the percentage of inodes that are used.
To use the ‘find’ command, navigate to the directory that you want to check and type ‘find . -print0 | xargs -0 stat –format=”%h” | sort -nr | head -1’. This will show the number of inodes for the given directory tree.
