shebang    
n. 事情,工作,陋屋,住所

事情,工作,陋屋,住所

shebang
n 1: an entire system; used in the phrase `the whole shebang'

Shebang \She*bang"\, n. [Cf. {Shebeen}.]
1. A jocosely depreciative name for a dwelling or shop; a
primitive dwelling; a shanty. [Slang, U.S.]
[1913 Webster]

2. The structure of an object, process, organization, or
anything viewed as complicated; -- used primarily in the
phrase

{the whole shebang}; as, it comes with unnecessary frills,
but you have to buy the whole shebang. [informal]
[PJC]

3. (computers) [Possibly derived from shell bang; the
character ! is referred to in some computer contexts as
bang.] The character sequence #!, which frequently begins
shell scripts in a Unix system.
[PJC]

(Or "shebang line", "{bang path}")
/sh*-bang'/ (From "{sharp}" and "{bang}") The {magic cookie}
"#!" used in {Unix} to mark the start of a {script}, e.g. a
{shell script} or {Perl script}.

Under {Unix}, if the first two bytes of an {executable} file
are "#!", the {kernel} treats the file as a script rather than
a {machine code} program. The word following the "!" (i.e.,
everything up to the first {whitespace}) is used as the
{pathname} of the {interpreter}. For example, if the first
line of an executable is

#!/usr/local/bin/perl

the script will be treated as a {Perl} script and passed as an
argument to /usr/local/bin/perl to be interpreted. Some
variants of Unix also allow one or more parameters to be
passed to the interpreter, for example, you can write

#!/usr/bin/perl -w

and the script will be started as if you typed

/usr/bin/perl -w

on the command line. Also, most modern kernels ignore any
whitespace between the "!" and the interpreter pathname. Even
some modern kernels have fairly small limits (e.g. 32) on the
length of line they will accept, making long pathnames and
arguments somewhat unportable.

[Does anyone call this a "magic string"?]
