What is the shebang ( #!/bin/bash).
7,596
When a file script starts with the shebang directive
#!langpath args
and has execution permissions set, Unix will "replace it" by
exec langpath args path-to-the-script.
This ways, typically:
langpathdefines the language to be used, ans should be the path of an executable interpreter of the (programming) language (ex: '/usr/bin/python')- the language should accept a script file as an argument
- the language should ignore the
#!...directive as a comment

why do we use shebang in the beginning of a shell script file. does the script will run without it.
I tried running it without shebang in shell script but it didn't run.

guiverc about 6 yearsthe #! helps the interpreter recognize the code; be it sh, bash, tsch, csh, ksh, .. perl, python .... (which at times can look alike for short scripts) [and thus know which interpreter is required to run it]
