mknod: Make block or character special files
mknod creates a FIFO, character special file, or block special
file with the specified name. Synopsis:
mknod [option]... name type [major minor]
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.
The arguments after name specify the type of file to make:
When making a block or character special file, the major and minor device numbers must be given after the file type.
The program accepts the following option. Also see section Common options.
chmodand uses 0666 minus the bits set in the umask as the point of departure. See section File permissions.
