One well-known scripting language python, JavaScript
In my understanding it seems python interpreter is installed in the system's various python: Built-in python, brew python, conda python in general usr / bin folder there will be soft at the python2 python3
For JavaScript, I think the most important applications or browsing the web. At this time, the system default browser has become such a scripting language interpreter.
shell script is a special script, in my opinion is a set of shell commands (distinguished from the core) is. At this time a variety of shell (bash, zbash, etc.) became the script interpreter.
Here is a shell script examples:
#! / bin / bash echo " the Hello World! " # This is a statement
The first line 1 #!is an agreed mark, which tells the system what the script requires an interpreter to perform that which Shell use; the latter /bin/bashis to indicate the specific location of the interpreter.
A python file recent head contact also the case:
#!/usr/bin/python3 """Our own little animal farm."""
In python, in addition to the file header #! # Sign behind all the action indicates a comment line.
