In Linux or Unix grep is a command which comes pre-installed with the system. if it is not present in your system you can install this by running the below command in your terminal.
$ sudo apt-get install grep
It is widely used command in day to day tasks. This command is used to search a regular expression or string in a text file. Grep stands for global regular expression print.
Syntax:
$ grep "string" file name
If you wish to search something across current directory and inside all the sub- directories you can use -r flag with this command to search recursively.
Syntax:
$ grep -r "string-name" *
