There is a lot to unpack in 'man find'. Thank you for your service!

This series is the best I've found regarding Linux! Thank you so much for that!

Awesome as always Jay! Extra thanks for the tips on Lacuna Coil, havent heard of them! Btw, I bought your book Mastering Ubuntu server 18.04, half way through it now and love it! Keep up the good work!

Simple, but incredibly useful. Thanks!

I can't thank you enough for all your videos. Been craming to learn linux so I can use it for a big chia farm.

Thanks for that, you had good reasons for doing what you did, some people will show you how to use commands and then I think why would you want to do that, lol. I'm so glad you like making these instructional videos, you are very good at it and your helping a lot of people. Thank you.

and the oscar goes to..... I love your videos man. Keep it up.

First example: If you omit the starting path, the $PWD is used, so you not even have to type the dot. `find -name *.txt` did only work incidentally, because without masking, the shell will do file name expansion, so if you happen to have one or more files matching the *.txt pattern in your current directory, the find command will see the list of expanded files. `find -name "*.txt"` instead is the thing to do, except you're sure, that there is no file matching your pattern in the current dir. Same problem in min. 21 while searching for *.log and 24 when searching for *.mp3. Min. 9: `find -delete instead of -exec rm {} +` is superior and present in GNUs find for ages. It is able to remove empty directories as well and is much better to type. Since find has so many options, you can talk about them for hours. I guess one of the most important options is searching for age with -mtime. I often know that I search for a file which is maybe 3 to 8 weeks old and it might be a Java file and I'm searching for, let's say, my usage of a JTable. `find -mtime +21 -mtime -56 -name "*.java" -exec grep JTable {} + -ls` If you don't pipe the output to grep, but use grep with exec, you can keep going using other find options. The ls gives a long file output, similar to `ls -l`.

I just tried the find -delete and it deleted all the contents of the directory instead of just what it found. The man says: Warning: Don't forget that find evaluates the command line as an expression, so putting -delete first will make find try to delete everything below the starting points you specified. I don't know how I'm supposed to use this command. Fortunately I didn't lose anything important.

@@iconoclastsc2 Well, for most options, the order of them doesn't matter, for example `find . -name "*.java" -mtime -3` will find the same files as `find . -mtime -3 -name "*.java`. But if you specify `-delete` in front of other criteria, those other criterias are only considered AFTER deleting, so `find . -mtime -3 -name "*.java -delete` will only delete .java-files, which are less than 3 days old, but find . -mtime -3 -delete -name "*.java` will delete all files less than 3 days old and the following resistriction with `-name "*.java"` is too late. Checking, which file might get deleted isn't trivial either, since '-delete' implies `-depth` which means the deeper files will get deleted before the less deep files, which is important for directories, which can only be deleted, if they are empty.

Good advice on quoting any glob patterns with -name - but I never use -delete because it is tricky and difficult to always get right - instead I use -ok rm -v {} \; or -exec rm -iv {} \; to force an interactive prompt to confirm each deletion and see what was deleted - or for a large number of files, first produce a list of matching files like he does in the video - then delete the list directly with something like xargs rm -v

@zartajmajeed

Technically "-name", "-mtime" etc are not options to the find command - find actually has just a handful of options like "-H" and "-D" - these other terms that start with a dash are part of the find expression language - they're called "primaries" - they look like options and even act a bit like options but they're not options - think of them like little boolean functions that combine to form the complete query expression - realizing this helps with a lot of confusion around find expressions

Instead of jumping all the way to exec you shouldda explain other optiones to narrow the search like mtime, ctime, find by permissions, exclude dirs (not filtering them out with grep -v) etc.

Thanks for the info. By the way, I noticed you said slash when you were indicating a backslash. I corrected it mentally myself, but others with less experience may not, and may accidentally type a slash instead, which would have unintended results when trying to escape the semicolon.

Can you do a detailed video on grep?

How do I copy with cp and exclude all files including files without extensions from a MTP mounted android phone ?

HI Jay, Yes, I followed this "lecture" about find today, because I was hoping that you would be able to help me with a challenge. Every month, I want to copy from a tree of directories and paths, the additions that were created some 30 days ago. Ideally, I have a tree of folders /backup/2021/0101 /backup2021/0201 .... As an example, the contents of 2021/0201 should contain only the new files to backup for that month. I was considering to use find's -mtime somehow. I am not sure if that is what I need to use. I was reviewing your examples, and did not see a way to do date range exclusion/selection with find. man and info pages were not too helpful. Have you some example from one of your private utilities that you can share? After some research, I also discovered pax a similar program to find. Perhaps pax is the utility to use. Your opinion or recommendation would be preferred. Regards from Montreal Quebec Leslie

Does this applicable to mac terminal? I dont see the "exec" working.

video starts at 2:58

By not quoting `'*.txt'` you risk matching files in your current directory: 'touch {a,b}.txt;find . -name *.txt' will fail.

I toured with Lacuna Coil in the 2000's when they opened for a band I worked as guitar tech for (Type O Negative) and also for a short run just with them afterwards. Great music and great people. Do I get a free question? I'm trying to backup photos from my Windows drive in Linux but exclude files that have parentheses. All files containing parentheses are duplicates, for example pic(1).jpg. So I want to find pic.jpg but exclude pic(1).jpg and copy all the pic files onto a backup drive. How might I use 'find' to exclude any files with a parenthesis?

I have been using Linux on a desktop for 4+ years now, but I never noticed you cannot open folders which do not have the x permission. Mind blown :D

Run the command again, but escape the asterisk. For example: $ find /home/Mason -name \*.txt To understand why you ran into your issue, run this: $ ls -l *.txt You will see more than one match. Due to having multiple matches, those matches are applied to your "find" command line. To test what you originally ran (which gave you the error), then run it again, with the echo command: $ echo find /home/Mason -name *txt You will see that the shell replaces the *txt with all matches, and that is what screwed up the find command. Jay did not run into this problem, because he never had any matches to *.txt in his working directory. So the shell kept the asterisk intact and sent it to the find command. For example, if you were to run: $ echo find /home/Mason -name *somefile-that-is-not-here-blah-blah-blah then the above will leave the asterisk there, because the shell will not match it to any files (which is how Jay avoided getting tripped up with his examples). Note that if you have a single file that matches the *.txt criteria, then if you do not escape the asterisk, you will end up searching for only that one file. Always escape the "*" when using the find command (and lots of other commands, too). Escape the ? character, too. Cheers!

@deprimarvin5382

There really is a difference in how the command to be executed is build. If I got the man page right, with "\;" the given command is executed for each and every finding. If you have 5 findings, the command will be executed 5 times. With "\+" (this should be escaped as well) the command is executed only once with all the findings added to the command at the end. Therefore the "{}" must be the very last argument before "\+". So if you have 5 findings here as well, the command will be executed once with all 5 findings added as arguments. Some examples: find ~/Documents -name \*.txt -exec cat \{\} \; findings file1.txt, file2.txt, file3.txt Will result in: cat file1.txt cat file2.txt cat file3.txt find ~/Documents -name \*.txt -exec cat \{\} \+ findings file1.txt, file2.txt, file3.txt Will result in: cat file1.txt file2.txt file3.txt Another example: You want to create an archive off all your JPGs. What happens, if you use this command? find ~ -name \*.jpg -exec tar -czv pictures.tar.gz \{\} \; Well, the tar command is executed for every finding, overwriting the archive each time. In this case you should use: find ~ -name \*.jpg -exec tar -cvf pictures.tar.gz \{\} \+ Hence all the found files are given as a parameter to the tar command, resulting in a tar ball with all the files you want. I hope that makes any sense to you.

If you remember significant parts of the filename, yes. With find you can search for files, modified 6 to 8 weeks before with a size below 50k, user u and permission p, exclude significant parts of the file system, youngest files without rerunning updatedb and search files in directories, omitted by updatedb. Then you may perform different operations with -exec on them, print output in customized way with -printf.
