<h3 /><h3>What is Grep command?</h3>
One of the most potent and often used tools in Linux is the grep command, which stands for "global regular expression print".
Each line that matches a pattern is sent to standard output by grep after it searches one or more input files for such lines. Grep reads from the standard input, which is often the result of another program, if no files are given.
Grep is instructed to display the line number of any lines that include a string that matches a pattern when the -n (or —line-number) option is used. When this option is selected, grep publishes the results of the matches to standard output along with the line number.
