问题
Some scripting languages (such as Python or Bash) use # for comments.
#!/usr/bin/env python
print 'hello, world'
I can run the script:
python script.py
Or
./script.py
Is it possible to make JavaScript support shebang?
回答1:
Yes, you can simply use #!/usr/bin/env node (or whatever the name of your JavaScript interpreter is, it works fine with js (spidermonkey), too).
[me@hades:~]> cat > test.js
#!/usr/bin/env node
console.log('hi');
[me@hades:~]> chmod +x test.js
[me@hades:~]> ./test.js
hi
Most likely both interpreters test if the first line begins with #! and in this case it is skipped.
