1 00:00:01,910 --> 00:00:03,410 Hello everyone. 2 00:00:03,620 --> 00:00:08,950 In this lecture let's talk about command find. 3 00:00:09,020 --> 00:00:13,850 But before starting to show you some comments just check the mail first 4 00:00:18,780 --> 00:00:25,890 it is one of the biggest Menlo because find command is a very complex and have many possibilities how 5 00:00:25,890 --> 00:00:27,300 to use it. 6 00:00:27,390 --> 00:00:29,990 We will cover a just few of them. 7 00:00:30,660 --> 00:00:36,390 So when we want to find some file or directory we are starting with keyword. 8 00:00:36,510 --> 00:00:37,080 Find 9 00:00:40,460 --> 00:00:46,300 followed by starting point which is place from where the command should start searching. 10 00:00:46,310 --> 00:00:53,120 So I will use directory home and now I need to specify name or file or directory which I would like 11 00:00:53,120 --> 00:00:53,690 to find. 12 00:00:53,690 --> 00:01:00,690 So I am using Desh name space and name of a file or directory let's say config. 13 00:01:00,740 --> 00:01:05,470 We have created in last lecture after executing this command. 14 00:01:05,480 --> 00:01:06,920 I see three findings. 15 00:01:06,920 --> 00:01:09,380 I have three config files. 16 00:01:09,380 --> 00:01:19,610 We can specify to find command what type should it search for when we specify type with parameter f 17 00:01:25,260 --> 00:01:33,650 it will search only for files and when on the other hand we use Type D. 18 00:01:36,350 --> 00:01:39,470 It will search for directories with the name config. 19 00:01:40,220 --> 00:01:51,420 And we see that no conflict directory was found under my home directory we can find command use wildcards. 20 00:01:51,480 --> 00:01:53,740 Please be Don't afraid now about it. 21 00:01:53,750 --> 00:02:02,850 We will cover it lately but for now I can try to find all s h files under starting point. 22 00:02:02,880 --> 00:02:03,930 Home returned 23 00:02:06,600 --> 00:02:18,680 and that name asterisk dot S H represents all s h files let's say that I want to search only for files. 24 00:02:18,970 --> 00:02:22,420 So we need to specify type F 25 00:02:26,000 --> 00:02:30,510 so I see that I have a lot of files with ext dot s h 26 00:02:34,080 --> 00:02:42,360 so let's make something more interesting with it it please note that find didn't search only in specified 27 00:02:42,390 --> 00:02:46,650 directory but also in its sub directories and so on. 28 00:02:51,260 --> 00:02:54,990 So now we can tell. 29 00:02:55,570 --> 00:02:56,560 To find common. 30 00:02:56,620 --> 00:02:59,800 To search only in starting point directory. 31 00:02:59,800 --> 00:03:07,540 Using parameter Maxim then followed by number one. 32 00:03:07,540 --> 00:03:15,590 This will ensure that find will search for as far as h files only inside home Richard directory and 33 00:03:15,590 --> 00:03:16,420 run around it. 34 00:03:16,420 --> 00:03:18,150 I can only see two files. 35 00:03:18,220 --> 00:03:23,070 That means that in home Richard are only two files of an extension. 36 00:03:23,230 --> 00:03:35,980 As H good I can now edit max depth parameter to number two and I see debt find common. 37 00:03:36,050 --> 00:03:45,890 Found more files with max depth set to 3 which means search also in sub directories of sub directories. 38 00:03:45,890 --> 00:03:49,410 I have much more findings as find. 39 00:03:49,410 --> 00:03:51,020 Command is really complex. 40 00:03:51,020 --> 00:04:01,560 I can search only for files which were modified more than 50 days ago using M time parameter. 41 00:04:02,120 --> 00:04:12,170 So at the end I can add another parameter M time and specify plus 50 v means search also on. 42 00:04:12,290 --> 00:04:14,710 Sorry search only for files. 43 00:04:15,480 --> 00:04:21,870 V2 are modified more than 50 days ago and it's quite a lot. 44 00:04:21,870 --> 00:04:30,960 If I change M time to only 50 without plus symbol final search for files modified 50 days ago no file 45 00:04:30,960 --> 00:04:31,560 was found. 46 00:04:31,560 --> 00:04:39,470 In my case and similarly when using minus symbol fine will search for files modified less than 50 days. 47 00:04:39,490 --> 00:04:49,860 In my case only 3 files similar parameter S M time is a time it represents when the file was access 48 00:04:54,690 --> 00:05:03,720 now let's use another other parameter for searching and it is a parameter called size. 49 00:05:03,890 --> 00:05:16,520 For example let's say search inside my home directory search for files only so find 0 Richard which 50 00:05:16,520 --> 00:05:25,950 is my home directory or I can use Tilde symbol to represent my home right at 3. 51 00:05:26,540 --> 00:05:38,360 Search for files only that means type is F and use parameter size and search for files bigger than 5 52 00:05:38,360 --> 00:05:42,550 megabytes few files in my home directory. 53 00:05:42,560 --> 00:05:46,810 Var found good. 54 00:05:46,940 --> 00:05:49,930 This was short summary about find command. 55 00:05:50,000 --> 00:05:51,340 What can you do with it. 56 00:05:51,350 --> 00:05:52,640 How to use it. 57 00:05:52,850 --> 00:06:00,800 And maybe if you haven't used to find command before you might feel kind of lost as so many parameters 58 00:06:00,800 --> 00:06:03,310 are there but don't be afraid. 59 00:06:03,320 --> 00:06:10,370 Practice make it better and after you finish this scores and start making your own scripts you will 60 00:06:10,370 --> 00:06:12,230 find the find. 61 00:06:12,230 --> 00:06:13,430 Come on not so hard. 62 00:06:13,430 --> 00:06:13,910 Tools.
