findįor the find command, this task is straightforward: sudo find /tmp -empty -type f,d Finding empty filesĪ number of the commands mentioned above have options specifically for finding empty files. The du or find commands are more appropriate for such a task. GNOME's desktop Files application provides typical GUI results:Īs can be seen above, sorting by the Size column isn't entirely helpful with respect to finding all files larger than 50 MiB. locateīecause the locate command's database does not contain file size information, you can't list files larger than 50 MiB solely with locate. In the above, %k provides the file size in KiB (as opposed to %s bytes). A more accurate rendition follows: sudo find / -size +50M -printf "%p %y %k KiB\n" 2>&- | column -t Note that 140737477885952 bytes is just under 128 PiB, which is clearly incorrect. The column -t command creates columns based on whitespace characters. The %p returns the filename, %y the file type, %s the size in bytes, and \n generates a newline character (for details, execute man find). To view just the file path, type, and size, you can use the -printf option, as shown: sudo find / -size +50M -printf "%p %y %s bytes\n" 2>&- | column -t The 7th column provides the size of each file, in bytes. To view the size of each file in bytes, you can use the -ls option (and 2>&- to remove the error messages): sudo find / -size +50M -ls 2>&. The following finds all files (excluding directories) larger than 50 MiB: sudo find / -size +50M The last row shows that the disk contains 2.8 GiB of data in total. You can can also sort by file size: sudo du / -ha -threshold=50M 2>&- | sort -h To suppress (the four) error messages, you can use the 2>&- argument. The -h option provides standard (human) file sizes and the -a option includes files as well as directories: The du command was designed specifically for this task: sudo du / -ha -threshold=50M For this task, we can add the du command to our list of likely suspects: du Let's say we would like to find all files larger than 50 MiB. Without the wildcard character ( *), the GNOME desktop Files application provides essentially the same information as the find command: Interestingly, even with the -e option, the locate command does not find the /run/blkid/blkid/tab.old file (whereas find does). In the following, the -i option ignores case: sudo locate -i *.old Note that the -iname option ignore case whereas -name does not. findīecause we're searching for all files, we use the sudo command to avoid permission errors and start the search from the root directory ( /): sudo find / -iname *.old In the following examples, we'll search for all files with the. You can produce analogous results using the GNOME desktop environment: Using the recursive -R option allows the standard ls command to produce similar results: ls -Rlha To resolve this issue, you can update the database with sudo updatedb (which might take some time) or use the -e option that only lists files existing at the time the locate command is run (essentially equivalent to find): locate -e * ls Recently modified files may not be reflected in the database. The speed of locate comes at a price, however. The locate command is similar to find but requires a pattern (the wildcard character in this case): locate * The unadorned find command recursively list all files from the current directory: find To list all files from the current directory down, the following commands may be used: find To learn how to access your remote Ubuntu computer using GNOME, see Using Windows Remote Desktop with Ubuntu 20.04 TLS. Additionally, the desktop environment examples are based on GNOME. The locate command can be installed as follows: sudo apt install mlocateīecause everything in Unix-like operating systems, including Ubuntu, is considered a file, the term "file" will also indicate "directory" unless otherwise called out. The locate command is often faster than find because it maintains a database of all files which is updated every 24 hours. Note that one of the command we'll use is locate, which does not natively come with Ubuntu. We'll also go over how to run one or more commands on each file found. old extension or finding all files and directories larger than 2 GB. In this tutorial, we'll go over a number of methods for finding files and directories (i.e., folders) in Ubuntu 20.04 LTS, such as finding all files with a.
