#Console command find file linux install#

The second example that we will look at is creating a hard symbolic link to the ‘ cal‘ utility, Figure 2.3 shows the command used to create the hard symbolic link.

Lrwxrwxrwx 1 root root 12 18:25 /root/cal -> /usr/bin/calįigure 2.2: Creating a soft symbolic link to the ‘cal’ utility.Īs you can see from Figure 2.2 the ‘ cal‘ utility was successfully created and ‘ls -l’ shows that the /root/cal file points to the /usr/bin/cal file. Linux-9sl8:~ # ln -s /usr/bin/cal /root/cal

Figure 2.2 shows the command used to create the soft symbolic link. The first example creates a soft symbolic link for the ‘ cal‘ utility which is stored within the /usr/bin directory. Figure 2.1 shows the syntax of create a symbolic link.Īs you can see in Figure 2.1 the first argument is the actual filename you would like to point to and the second argument is where you want the symbolic link (shortcut) to be. However, if you want to create soft links you need to provide the -s qualifier. This command with no qualifiers and two arguments will create a hard link. The command that you use to create symbolic links is ‘ ln‘. However, you can create soft links across multiple devices. If you have created separate partitions for /home and /usr you cannot hard link any files from /usr to /home. After the scan is complete, you can sort the results by file size in order to see your largest files and directories.You cannot create hard links across multiple devices e.g. Once QDirStat is installed, open the application and select where you would like the program to scan for files.

#Console command find file linux install#

Ubuntu, Debian, and Linux Mint: $ sudo apt install qdirstatįedora, CentOS, AlmaLinux, and Red Hat: $ sudo dnf install qdirstatĪrch Linux and Manjaro ( install from AUR): $ git clone

Use the appropriate command below to install QDirStat with your system’s package manager. There are a lot of different programs that can do the job. If you need to sift through a lot of files, or just don’t want to fool around with the command line, a GUI application can make it easier to find files based on their size. size +1G -exec ls -1hSs + | head -3Īs seen in these examples, the ls and find commands are both perfect tools when you need to search for files based on their size. This command will find and list files bigger than 1 GB. For the best of both worlds, we can use find to search for files, and combine it with the ls command to list the size in the results, in descending order from biggest to smallest. This command will search for files between 5 GB and 10 GB. It’s also possible to search for files between certain sizes, by combining two -size options in find. Let’s find files that are under 2 GB by using the same syntax as above, but using a - “less than” symbol instead. We can also use find to search for files under a certain size. The + is “greater than” and 2 GB is specified as 2G in the syntax. The -size option tells find to search for files of a certain size. Let’s find files that are more than 2 GB in file size. The find command is an even better way to list files based on their size. This output shows how much space each directory is using, then lists the files (largest to smallest size) in each subdirectory.Įxample 3. If your files are separated into subdirectories, you can add the -R option to get files listed recursively. You’ll also see a total of all file sizes on the first line of the output.Įxample 2.

$ ls -1hSsĪs you can see from the output, files are listed largest to smallest. Include the -1 option to list one file per line, the -h option to put the sizes in human-readable format, the -S option to sort the files by their size, and the -s option to show each file’s size. If you already know the location of the files you want to check, we can use the ls command to list files by their file size. Find Files of Certain Size (With Commands)Įxample 1. Check out some of the examples below to get started. In this guide, we’ll go over the commands you can use to find files and directories based on their size in Linux.
