Don't knock it, it's the only dual CPU machine I have....
Anyway, the best I can offer is for HPUX 11.11

If the file is a special file, the size field contains the major and minor device numbers rather than a size.
Maybe it's an stupid question but remeber... I'm Junior..
I use command line to run programs, and some of them gives a lot of information when, for example, you open a window or other actions. That's really bad because my terminal gets full of unwanted messages, so I use "bin file & >/dev/null"... (1 Reply)

echo "hello" > /dev/null 2>1 (3 Replies)
I apologize if this question has been answered else where or is too elementary.
I ran across a KSH script (long unimportant story) that does this:

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

name A special file to be created.

|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.
