This is a small rust version of grep (globally search a regular expression and print). According to Wikipedia, grep is a "command-line utility for searching plain-text data sets for lines that match a regular expression. Its name comes from the ed command g/re/p (globally search a regular expression and print), which has the same effect: doing a global search with the regular expression and printing all matching lines."
