Linux find file size in folder8/13/2023 ![]() By adding a delete flag, you would remove potentially important directory structures. For instance, if you forget to include -type f in a search for empty files, you get directories in your results. Technically, you can use find to remove empty files, but programmatic removal of files is dangerous. How well do you know Linux?

The find command combined with the -type d option is a better choice: $ find ~/Public -type d List just directoriesĪ shortcoming of the ls command is that you can't filter its results by file type, so it can be noisy if you only want a listing of directories in a path. home/seth/.local/share/gnome-shell/gnome-overrides-migratedĪs long as you're using the GNU version of find, you can include multiple file types in your search results: $ find ~ -type f,l -name "notebook*" home/seth/.local/share/keyrings/user.keystore home/seth/.local/share/keyrings/login.keyring You can display files, directories, symlinks, named pipes, sockets, and more using the -type option. home/seth/Documents/foo.txt:Penguins are fun. home/seth/Documents/Foo.txt:I like penguins. $ find ~/Documents/ -name "*txt" -exec grep -Hi penguin \ This can be especially useful when you need to search for a file by content rather than by name, or you need to search by both. ![]() ![]() In fact, one of the options in find enables you to execute a different command on whatever results find returns. Find by contentĪ find command doesn't have to perform just one task. Notice that I don't use 2>/dev/null in this instance because I'm only listing the contents of a file path within my home directory, so I don't anticipate permission errors. The ls -R command lists the contents of a directory recursively, meaning that it doesn't just list the target you provide for it, but also descends into every subdirectory within that target (and every subdirectory in each subdirectory, and so on.) The find command has that function too, by way of the -ls option: $ find ~/Documents -lsģ554235 0 drwxr-xr-x 05:36 /home/seth/Documents/ģ554224 0 -rw-rw-r- 05:36 /home/seth/Documents/Fooģ766411 0 -rw-rw-r- 05:36 /home/seth/Documents/Foo/foo.txtģ766416 0 -rw-rw-r- 05:36 /home/seth/Documents/Foo/foobar.txt If you can't remember the exact name of the file, or you're not sure whether you capitalized any characters, you can do a partial and case-insensitive search like this: $ find / -iname "*foo*txt" 2>/dev/null Use 2>/dev/null to silence permission errors (or use sudo to gain all permissions). When you know the name of a file but can't remember where you saved it, use find to search your home directory. Whether you're on your own computer or trying to support someone on an unfamiliar system, here are 10 ways find can help you locate important data.
