Linux Commands: creates a FIFO, character special file, or block special file
mknod-Linux Command
mknod
creates 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.
