What does 'grep' mean?
The Wikipedia entry for grep states:grep is a command line utility originally written for use with the Unix operating system.
The name comes from a command in the Unix text editor ed that takes the form:
g/re/p
This means "search globally for matches to the regular expression re, and print lines where they are found".
一直使用，原来这个意思啊，在vim中 g/re/p，呵呵
