Question: 1 / 400

What is the purpose of the 'grep' command?

To search text in files

The 'grep' command is a powerful tool used in Linux for searching text within files. It stands for "global regular expression print" and allows users to search for specific patterns or strings in files and print lines that contain those matches. This is particularly useful for parsing log files, searching through code, or finding specific information in large sets of text data. By using various options, users can refine their searches further, such as making them case-insensitive, displaying line numbers, or counting occurrences of matches.

The other options relate to file management tasks but are not associated with searching text. Deleting files is handled by commands like 'rm', copying files is done using 'cp', and moving files is accomplished with 'mv'. Each of these commands serves distinct purposes within file system manipulation but does not involve searching for text.
