problem of matching mailboxes in the first example above is resolved.The formula for regular A: R "\[email protected] (qq|163|126). com" is a matching capture group, so got [' QQ ', ' 163 ', ' 126 '] this list;The formula of regular B: R "\[email protected] (?: qq|163|126). com",?: Turns the capturing group into a non-capturing group, so that the formula can be matched from beginning to end, so the successful ['[email protected] ', '[email protected]', '[email protected]' This list of mailboxes

In linux shell, the meaning of "2> 1" is analyzed: it takes 10 hours to compile the Android operating system code, which may cause problems during the compilation process and facilitate debugging.You need to output the compilation process to the file. In this way, you can also set automatic shutdown.

standard output is directly input to/dev/null, while 2> 1 redirects the standard error to the standard output, therefore, when an error occurs in the program, it is equivalent to the error flow to the left, and the left is still input to/dev/null.
It can be understood that, if it is written in the middle, it will cut off the standard output of the specified output file
You can use
