mknod
mknod(1M) System Administration Commands mknod(1M) NAME
mknod - make a special file SYNOPSIS
mknod name b major minor mknod name c major minor mknod name p DESCRIPTION
mknod makes a directory entry for a special file. OPTIONS
The following options are supported: b Create a block-type special file. c Create a character-type special file. p Create a FIFO (named pipe). OPERANDS
The following operands are supported: major The major device number. minor The minor device number; can be either decimal or octal. The assignment of major device numbers is specific to each system. You must be the super-user to use this form of the command. name A special file to be created. USAGE
See largefile(5) for the description of the behavior of mknod when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes). ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ SEE ALSO
ftp(1), in.ftpd(1M), mknod(2), symlink(2), attributes(5), largefile(5) NOTES
If mknod(2) is used to create a device, the major and minor device numbers are always interpreted by the kernel running on that machine. With the advent of physical device naming, it would be preferable to create a symbolic link to the physical name of the device (in the /devices subtree) rather than using mknod.
