Find command basic syntax

The syntax is as follows:
find where-to-look criteria action
find /dir/to/search -name filetosearch
find /dir/to/search -name «*.c»

Sample outputs without permission denied spam from find command:

How does it works?

The 2>/dev/null at the end of the find command tells your shell to redirect the error messages (FD #2) to /dev/null, so you don’t have to see them on screen. Use /dev/null to to send any unwanted output from program/command. All data written on a /dev/null special file is discarded by the system. To redirect standard error to /dev/null and store file list to output.txt, type:

Exclude all “permission denied” messages from “find” command on Linux

There is one problem with the following command. It would filter out all error messages created by find command, not just the permission denied ones:

Conclusion

You learned how to hide and fix permission denied messages when using the find command on your Linux, Unix, or macOS-based systems. Of course, we can also run the command as sudo when possible but avoid all this mess. Unfortunately, you will not get sudo or root access at all times. Hence, we talked about various methods here. For your ready references, sudo syntax would be as follows:
sudo find /dir/to/search -name «pattern» -action
sudo find / -name «jail.conf» -print
Please see find/bash command man page online or read it by typing the following man command:
man find
man bash
man zsh
man ksh

Both errors and warning are thrown into stderr is there any way we can identify that the command has a warning in it and not the error ??
Apart from checking the return code !!

Just use sudo (assuming you’re not running it in a script)

Спасибо.
Но у этого способа есть недостаток — убираются все сообщения об ошибках, а нужно только не замусоривать вывод сообщениями о директориях к которым нет доступа. Я подумал, что разработчики find предусмотрели такую возможность, но беглый просмотр

Пожалуй, способ указанный flank’er наиболее простой, но и у него есть недостаток — если локаль произвольная.
Всё же интересно, можно ли добиться желаемого только средствами команды find, без организации конвеера?
