What command is used to search for a specific text in files?

The command used to search for a specific text in files is grep. Grep stands for "Global Regular Expression Print" and is a powerful command-line utility in Unix and Linux systems that allows users to search through text files using patterns defined by regular expressions. When executing grep, you can specify a string or pattern to look for, and it will return all lines in the file where that string or pattern appears. This makes it ideal for querying logs, scripts, or any text-based file to find specific information efficiently.

Other commands, while related to searching, serve different purposes. For example, find is primarily used to locate files and directories in a file system based on various criteria like name, type, or modification time but does not search the content of files. The search command is not a standard command in Unix/Linux environments for finding text, and locate, although it can find files quickly, is designed to search for filenames and paths, not the content within files. Thus, grep is the correct and most suitable tool for searching text within files.
