Grep command is used to search text from files. It is a versatile pattern that invokes grep with –r. –R option search files recursively from subdirectories, starting from the current directory. The command is run from the top-level directory.
To Search Subdirectories To include all subdirectories in a search, add the -r operator to the grep command. This command prints the matches for all files in the current directory, subdirectories, and the exact path with the filename.
You can make grep search in all the files and all the subdirectories of the current directory using the -r recursive search option: grep -r search_term .
To recursively search for a pattern, invoke grep with the -r option (or --recursive ). When this option is used grep will search through all files in the specified directory, skipping the symlinks that are encountered recursively.
grep -r "texthere" . The first parameter represents the regular expression to search for, while the second one represents the directory that should be searched. In this case, . means the current directory.
Note: This works for GNU grep, and on some platforms like Solaris you must specifically use GNU grep as opposed to legacy implementation. For Solaris this is the ggrep command.
