How to find a file in linux

The page explains that in Unix-like systems you can use the find command to locate a file. It gives the basic pattern find {directory-name} -name {filename} and then shows two uses: searching from / when you do not know where the file is, and searching inside a specific directory such as /Users/mkyong.

Reading notes

#

• Use find {directory-name} -name {filename} to search for a file.
• To search the whole system, run sudo find / -name 'testing.txt'.
• Searching from / may require permission, so the example uses sudo.
• To search only within one directory and its subdirectories, run sudo find /Users/mkyong -name 'testing.txt'.
