Judes wants to locate a specific string in a lengthy text file. Which tool should he employ to efficiently discover every instance of the text he is looking for?

Judes can use the Linux grep command to explore files or directories and locate strings. The cat command is an abbreviation for concatenate and is capable of creating files, displaying their contents, or merging files. On the other hand, the head and tail are utilized to view either the start or the end of a file.
