The appearance of the program is very similar to the command prompt window in Windows. In order to start the search, you need to enter the grep –r "" command in the grep window, where in quotation marks you must specify the approximate name of the desired file or a piece of text. After that, the utility will immediately begin to study libraries in search of data. In grep, searching the contents of files on Linux is pretty slow, so you'll have to wait

If the user needs to find an executable program file that he accidentally deleted or lost, the managed command which will come to his aid. For the best search, use the full command /home/username/.local/bin / "...", where you must enter the file name in quotation marks. This command is the easiest way to search the contents of files in Linux.
Finding a file with locate
The last way to find files on Linux is with the locate command. It should be borne in mind that with its help you can find a file only by its exact name, unlike the previous methods.
