In some operating systems, the null device is a device file that discards all data written to it but reports that the write operation succeeded. This device is called /dev/null
on Unix or Unix-like systems, NUL:
or NUL
on DOS and CP/M, \Device\Null
on Windows NT, nul
on newer Windows systems, NIL:
on Amiga operating systems, and the NL:
on OpenVMS. In Windows Powershell, the equivalent is $null
. It provides no data to any process that reads from it, yielding EOF immediately. In IBM DOS/360, OS/360 (MFT, MVT), OS/390 and z/OS operating systems, such files would be assigned in JCL to DD DUMMY.
In programmer jargon, especially Unix jargon, it may also be called the bit bucket or black hole.
The null device is typically used for disposing of unwanted output streams of a process, or as a convenient empty file for input streams. This is usually done by redirection.
The /dev/null
device is a special file, not a directory, so one cannot move a whole file or directory into it with the Unix mv
command. The rm
command is the proper way to delete files in Unix.
Null Device is an electronic pop band from Wisconsin, USA.
Null Device is an electronic band formed in 1995 by Eric Oehler, William Annis, and Tom Lawrence at the University of Wisconsin–Madison. After the amicable departures of Annis and Lawrence, Dr. Eric Goedken joined as a full-time lyricist and producer. Named after /dev/null, the group was originally an informal project for members of the university's Undergraduate Projects Lab interested in the techno music of the burgeoning rave scene. Through connections to Stromkern's Ned Kirby and a variety of DJ's from local clubs, the project slowly became more focused on vocal-oriented industrial dance music, driven by Lawrence's experimental audio software. It was at this point that Goedken joined the band full-time and Null Device became a more melodic electronic pop act in the mold of Depeche Mode and New Order. After some local and underground success, they were signed to Nilaihah Records in 2002.
While their label debut and early works are straightforward synthpop, their more recent works have seen a broadening of influences, taking cues from breakbeat, trip hop, house music and drum and bass and incorporating a wide range of ethnic influences and instruments. Subsequent releases have seen the use of dumbek, dholak, duduk, cumbus, sitar, dilruba and violin, as well as guest vocals by Arabic and Carnatic classical singers. Null Device has also contributed to various projects with a number of other industrial, synthpop and electronic artists, including Armageddon Dildos, B! Machine, Blind Faith and Envy, Caustic, The Dark Clan, Distorted Reality, The Gothsicles, Epsilon Minus, Hungry Lucy, Stochastic Theory and Stromkern.
Don't let it be said
Lightning never strikes twice
Storm clouds return now
Lights flash as they entice
I turn you in
Running from the cold
You look for answers
I know I'll never hold
Is this what you wanted?
Is this what you deserve?
Is this what we wanted?
Is this what we deserve?
Put on the rack
And under the gun
Waiting here in stillness
Put on the rack
And under the gun
Cast off the rising sun
In the spotlight
And under the gun
I wander endlessly
In the spotlight
And under the gun
Wait for the dawn to come
I refuse to believe that
Thunder always comes late
Hard winds speed on now
Circling around like fate
Those I deceive
Fleeing in this cold
They ask the questions
No answers will I hold
Is this what we wanted?
Is this what we deserve?
Is this what you wanted?
Is this what we deserve?
Never one to believe
In destiny's advice
Storm clouds descend now
They flash and pay the price
I switch you on
Running from the cold
They look for answers
I know I'll never hold
Stretched on the rack
And under the gun
Betray the future
Stretched on the rack
And under the gun
Wait for the dawn to come
In the spotlight
And under the gun
Watching fireflies
In the spotlight
And under the gun
