Create a FIFO, character special file, or block special file with the specified name.
Syntax mknod [options]... NAME Type [Major Minor] Options -m MODE --mode=MODE Set the mode of created files to MODE, which is symbolic as in `chmod' and uses 0666 minus the bits set in the umask as the point of departure. Type The type of file to make: `p' for a FIFO `b' for a block special file `c' for a character special file Major/Minor When making a block or character special file, the major and minor device numbers must be given after the file type.
Unlike the phrase "special file type" above, the term "special file" has a technical meaning on Unix: something that can generate or receive data. Usually this corresponds to a physical piece of hardware, e.g., a printer or a disk. (These files are typically created at system-configuration time.) The `mknod' command is what creates files of this type. Such devices can be read either a character at a time or a "block" (many characters) at a time, hence we say there are "block special" files and "character special" files.
