#! – shebang

Until today I only know the term hash-exclam for #!


„In computing, a shebang (also called a sha-bang, hashbang, pound-bang, hash-exclam, or hash-pling) is the character sequence consisting of the characters number sign and exclamation mark (that is, „#!„) when it occurs as the initial two characters on the initial line of a script.

Under Unix-like operating systems, when a script with a shebang is run as a program, the program loader parses the rest of the script’s initial line as an interpreter directive; the specified interpreter program is run instead, passing to it as an argument the path that was initially used when attempting to run the script. For example, if a script is named with the path „path/to/script„, and it starts with the following line:


then the program loader is instructed to run the program „/bin/sh“ instead (usually this is the Bourne shell or a compatible shell), passing „path/to/script“ as the first argument.

The shebang line is usually ignored by the interpreter because the „#“ character is a comment marker in many scripting languages; some language interpreters that do not use the hash mark to begin comments (such as Scheme) still may ignore the shebang line in recognition of its purpose.“


Shebang (auch Magic Line) bezeichnet bei unixoiden Betriebssystemen die Zeichenkombination #! am Anfang eines Skriptprogramms. Die Markierung mit Doppelkreuz und Ausrufezeichen führt dazu, dass das folgende Kommando mitsamt allen angegebenen Argumenten beim Aufruf des Programms ausgeführt wird. Der Dateiname wird dann als weiteres Argument übergeben. Andere Betriebssysteme – beispielsweise Microsoft Windows – nutzen die Technik nicht. Nur bei speziellen Umgebungen, wie dem Common Gateway Interface im Apache HTTP Server, spielt die Shebang-Konstruktion auf diesen Systemen eine Rolle.“


Japan Prize Award – Congratulations to Dr.Ritchie and Dr. Thompson

Congratulation for winning the Japan Prize Award and many thanks to Dr. Dennis Ritchie and Dr. Ken Thompson for the development of UNIX.

The Japan Prize (日本国際賞) is awarded to people from all parts of the world whose „original and outstanding achievements in science and technology are recognized as having advanced the frontiers of knowledge and served the cause of peace and prosperity for mankind.“ http://en.wikipedia.org/wiki/Japan_Prize

Dennis MacAlistair Ritchie (username: dmr, born September 9, 1941) is an American computer scientist notable for developing C and for having influence on other programming languages, as well as operating systems such as Multics and Unix. He received the Turing Award in 1983 and the National Medal of Technology 1998 on April 21, 1999. Ritchie was the head of Lucent Technologies System Software Research Department when he retired in 2007. http://en.wikipedia.org/wiki/Dennis_Ritchie

Ken Thompson (born February 4, 1943), commonly referred to as ken in hacker circles,[1] is an American pioneer of computer science notable for his work with the B programming language and his shepherding of the Unix and Plan 9 operating systems. Most recently Thompson is also the co-creator of Google’s programming language Go. http://en.wikipedia.org/wiki/Ken_Thompson

What the hell are you talking about?
We are talking about the „UNIX Time“. The UNIX is a number defined as the number of seconds elapsed since midnight Coordinated Universal Time (UTC) of January 1, 1970. You can easily calculate or save times with this number.“
