Issue2056

When parsing the command line args, exclamation points/bangs/!'s are ignored.

What platform? Works as expected on Ubuntu with Jython 2.7b1 for me:

$ cat /tmp/bang.py 
#!/usr/bin/env python

import sys

def main(args):
    print repr(args)
    return 0


if __name__ == '__main__':
    sys.exit(main(sys.argv))

$ ./dist/bin/jython --version
Jython 2.7b1+
$ ./dist/bin/jython /tmp/bang.py ! hello
['/tmp/bang.py', '!', 'hello']

Thanks for responding. The problem happens on 64-bit Windows 7. Running bang.py under jython and then python:

C:\temp>jython --version
Jython 2.7b1

C:\temp>jython bang.py ! hello
['bang.py', 'hello']

C:\temp>python bang.py ! hello
['bang.py', '!', 'hello']

BTW, I'm running Java 7 -- is that a problem?

C:temp>java -version
java version "1.7.0_21"
Java(TM) SE Runtime Environment (build 1.7.0_21-b11)
Java HotSpot(TM) Client VM (build 23.21-b01, mixed mode, sharing)

Nope, nothing to do with Java 7. It's a problem in the batch file related to use of ! as a variable substitution marker when setdelayedexpansion is in force. Any batch file wizards out there? (I've never mastered the things.)

We should simply solve with #1491 (native launcher for Windows), so I'm going to mark as a duplicate

#1491 is now fixed
