How to Find a File in Linux with the Find Command

The Linux find command is one of the most important and handy commands in Linux systems. It can, as the name suggests, find files on your Linux PC based on pretty much whatever conditions and variables you set. You can find files by permissions, users, groups, file type, date, size and other possible criteria using the find command.

The find command is available on most Linux distro by default, so you do not have to install a package for it.

In this tutorial we will show you how to find files on Linux using various common combinations of search expressions in the command line.

The most obvious way of searching for files is by name. To find a file by name in the current directory, run:

how-to-find-a-file-in-linux-photo

If you want to find a file by name that contains both capital and small letters, run:

find-iname-photo

If you want to find a file in the root directory, prefix your search with sudo which will give you all permissions required to do so, and also the ‘/’ symbol which tells Linux to search in the root directory. Finally, the -print expression displays the directories of your search results. If you were looking for Gzip, you’d type:

how-to-find-a-file-in-linux-gzip

If you want to find files under a specific directory like “/home,” run:
