It is just a reference and cannot be

Dev-CPP/mingw32 Environment Introduction (5) Review above: In the previous section "Dev-CPP/mingw32 Environment Introduction (4)", we introduced how to use static connection libraries. Today, we will introduce how to create your own mingw32 static Link Library. For the static Connection Library under Win32, I 'd like to know how to make it. So we will not introduce it here.

The following statements are often seen in shell: >/Dev/null 2> 1 Meaning: Dev/null indicates an empty device file. > Indicates the redirection location, for example, Echo "123">/home/123.txt 1 indicates stdout standard output. The default value is 1. Therefore, ">/dev/null" is equivalent to "1>/dev/nul

In some shell scripts, especially in crontab scripts, >/dev/null2>1 is often seen as such. In fact, this is very good understanding. We explain in two parts. 1. >/dev/null Everyone knows that ">" (Right angle bracket) in the Unix/linux shell means input to the meaning of the ">" to the left of the content to the ">" right.For example, Echo text>1.txt the text into the 1.txt file.So what is "/
