Linux/Mac Terminal Tutorial: The Grep Command - Search Files and Directories for Patterns of Text

You can also pipe the output of one command into grep to get certain matches. It's extremely useful once you learn the ins and outs. Let's get started...

I like that this guy just gets straight to the point and wastes no time. I like this man already!

6:35 $ grep -win -C 2 "find this string" ./*
8:05 $ grep -winr "Find that string even in subdirs" ./*
9:35 $ grep -wirl "List those files that contain this string in current directory dot" .
10:20 $ grep -wirc "List those files that contain this string and number of occurrences in current directory dot" .
11:10 $ history | grep "search for git commits in history"
12:00 $ history | grep "search for git commits" | grep "now narrow down to some string"
15:40 only for mac: $ brew install grep --with-default-names #to allow regular expressions based on perl, as shown in 17:56.
19:13 Homework!

Some folks are intelligent and smart but are horrible at teaching. Corey is smart, intelligent and born to be a teacher. While I am going to contribute on patreon right away, you have a gift that you can use to sell your videos at a small price to benefit and educate the population. Amazing

So glad I looked at this tutorial. I've known how to kind of use grep for a while. Some of these options are going to be super helpful to me in the near future. I should have looked in the man pages a long time ago!

[mickaelriga]

Great video ! Great explanation. I like that it goes beyond the basic use. Thank you for sharing.

Coincidentially, I had just tried out grep yesterday after completing the "Terminus" game. Today my colleague was very impressed when in a matter of seconds, out of 7500 case files, I picked those 40 or so which contained one certain word. also you can export the results easily into a file (I use &>>filename.txt (.csv also works)), which might come in handy if your boss wants "all the contracts with the Miller Company ASAP", or if you want to quickly mail a list of relevant files. As always, great video!

[JordanCrawfordSF]

Brilliant.

Thank you for taking the time to help me understand grep, I really appreciate your thoughtfulness Corey.

[gokiburi]
