What is the Search command in Linux?

Grep is a Linux / Unix command-line tool used to search for a string of characters in a specified file. The text search pattern is called a regular expression. When it finds a match, it prints the line with the result. The grep command is handy when searching through large log files.

How do I search in Linux terminal?

If you know where the file might be, open the terminal, navigate to the directory and run “find . [filename]”. That dot tells find to search on the current directory. If you want to search your Home directory instead, replace the dot with “~/”, and if you want to search your whole filesystem, use “/” instead.
