Find files and file content on the terminal can be achieved by the use of the find tool.

By far one of the best tools is „Silversearcher ag“, install it with sudo apt-get install silversearcher-ag. If you want to search for example recursive all folders, only php files for the search string „my Value“, simply type:

Find file/s containing a specific string in its name:

Now list all files that contain the word „searchTerm“

List all the occurrence and their respective line-number of „searchTerm“ in files. The parameter -n toggles the line-number, the parameter -H toggles the filename.

A handy tool as well is ack-grep (you have to install it first). Be sure to wrap the search-term in single quotes.
