 So and welcome today we're just going to be playing around a little bit with search patterns. The you're maybe familiar with some of these and I'm just going to throw a few in there that probably are less commonly used at least by novice users. So let's just let's just dump in I'm going to list out I have all these random files you got some jpegs gif or gif however you want to say it pngs a few PDFs all different names so let's see them out so of course I can go like this and I can say show me just the jpegs I can say just show me the PDF files I can say show me ones that start with cat or oh there's no PDF just show me files that start with cat show me only the ones that are cat.jpegs or pngs so we know that the asterisk here basically means fill in as many characters as you want so I'm looking for something that has cat and anywhere from zero or more here to dot jpeg and same here but with dot png but let's say we want specific numbers so I can say list asterisk dot at dot png and I'll get bat cat fat and mat jpeg but let's say I just want cat and bat you know those those returns I can say a b I'm sorry c and b so what we're doing here is we're looking for just one character there it's either c or b.png and of course we can change this to jpeg and we'll get jpeg or we can do an asterisk there so now we're looking for anything that starts with the letter c or b has at dot whatever and we'll get a list of those files so in here these braces are these brackets are basically every letter you put in there is considered an individual letter that we are putting into that search we can also say something like list question mark at dot png and here we are replacing that with any single character now in this particular case we can do this and we get the same results but if I was to just create a file here I'll say mat dot png so here we'll get all these because we're looking for anything at dot png but if I change this to a question mark here now it's going to list out anything with a single character there so an asterisk is however many number characters zero on up where a question mark is a single character so here it will leave out that mm at and if we want something with two characters at we can do that let's just create a file here real quick we'll call this bats dot png but with two t's now if we do that it'll list both those because we're looking for two letters at dot png and that's what we get here I'm trying to think if there's those are just some basics I wanted to go over and I think I did I can just you know review those but I just wanted to make this quick little thing to basically show you just between asterisk the question mark and using the brackets so again we can also do something like this let's see I can say book and now it's bringing up everything that has book and if I was to create a file here by way touch command just basically touches a file if it doesn't exist it creates an empty file so that's what I'm doing when I do that if that's confused you at all I should have mentioned that earlier let's do this 4 4 4 5 4 6 and we do 450 51 60 I can also create multiple files at once I can do something like this and change this to 4 3 2 in the first one we'll just touch that file that already exists now I can list that I can list out book it'll show me all books dot anything I can say just book dot PDF which is gonna list out the same things because there's no other files there I can say dollar sign here and we'll only list things with single digits there I can say anything that is book for whatever so it's going to give me 44 45 45 51 here I can do 6 and it's going to give me anything that has 46 that includes number 46 but final one things in the 460 range I can't change this to a question mark and now it's only showing me things that are in book 460 whatever with a single digit there so if I was to touch some files here again and make that this will still ignore that because even though there's a digit after that we're looking for a single digit but we go to digits and it'll show that file ignore the others so anyway just I give some review there on how these things work and that's about it thank you for watching please visit films by Chris calm that's Chris the K there's a link in the description to my website and there's also a link to my patreon page patreon.com forward slash malex 1000 there you can support me can also support me through PayPal if you go to films by Chris calm sports section there's a link there for that on my website you can also search through all my videos I do thank you for watching and I hope that you have a great day
