grep is a command-line utility for searching plaintext datasets for lines that match a regular expression. Its name comes from the ed command g/re/p (global regular expression search and print), which has the same effect.[3][4] grep was originally developed for the Unix operating system, but later became available for all Unix-like systems and some others such as OS-9.[5]
