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)

Hi expert,
May I know what is the difference between below cron tab entry ?
0,12 * * * * /abc/myscript.sh > /dev/null 2>&1
0,12 * * * * /abc/myscript.sh (7 Replies)
How are these two different? They both prevent output and error from being displayed. I don't see the use of the "&"
echo "hello" > /dev/null 2>&1
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:
if ; then
CAS_SRC_LOG="/var/log/cas_src.log 2>&1"
else
CAS_SRC_LOG="/dev/null 2>&1"

makedev
MAKEDEV(3) Linux Programmer's Manual MAKEDEV(3)NAME
makedev, major, minor - manage a device number
SYNOPSIS
#define _BSD_SOURCE
#include <sys/types.h>
dev_t makedev(int maj, int min);
int major(dev_t dev);
int minor(dev_t dev);
DESCRIPTION
A device ID consists of two parts: a major ID, identifying the class of the device, and a minor ID, identifying a specific instance of a
device in that class. A device ID is represented using the type dev_t.
Given major and minor device IDs, makedev() combines these to produce a device ID, returned as the function result. This device ID can be
given to mknod(2), for example.
The major() and minor() functions perform the converse task: given a device ID, they return, respectively, the major and minor components.
These macros can be useful to, for example, decompose the device IDs in the structure returned by stat(2).
CONFORMING TO
The makedev() major() and minor() functions are not specified in POSIX.1, but are present on many other systems.
NOTES
These interfaces are defined as macros. Since glibc 2.3.3, they have been aliases for three GNU-specific functions: gnu_dev_makedev(3),
gnu_dev_major(3), and gnu_dev_minor(3). The latter names are exported, but the traditional names are more portable.
