Get the complete command line as-is

wangzq

Hello,

I'm passing command line parameters to my browser, I need to pass the
complete command line as-is, for example:

test.py "abc def" xyz

If I use ' '.join(sys.argv[1:]), then the double quotes around "abc
def" is gone, but I need to pass the complete command line ("abc def"
xyz) to the browser, how can I do this?

I'm on Windows.

Thanks.

You can't. The quotes are gobbled by the command-line processor before
your program ever gets the chance to see them. You could try writing
your own command shell ... or learn how to quote the quotes.

I'm on Solaris and this works for me:

test.py '"abc def" xyz'



print sys.arv[1]

"abc def" xyz

OK, now I'm on Windows XP and things aren't looking too good.

It seems that \" will retain the quote marks but then the spaces get
gobbled.

But if you replace the spaces with another character:

python.exe test.py \"abc#def\"#123

then:

import sys
commandLine = "".join(sys.argv[1:])

prints commandLine.replace('#',' ')

gives:

"abc def" 123

Don't know if you can use that technique or not.

Came back for a second try and found out that:

python.exe test.py "\"abc def\" 123"

import sys
commandLine = "".join(sys.argv[1:])

print commandLine

gives:

"abc def" 123

python.exe test.py "\"abc def\" 123"

import sys
commandLine = "".join(sys.argv[1:])

print commandLine

gives:

"abc def" 123

With the surrounding quotes you actually only need:

commandLine = sys.argv[1]

As Windows command-line parsing seem to remove some chars, maybe you can
try to use the GetCommandLine() function from Win32 API (I dont know if
it is available in pywin32 package - you may need to write a wrapper
with ctypes).

Question: If you don't want to parse this as a command line, why don't you read
it as data via raw input or from some configuration file?

something like:

python program (pgm.py):

cmdline=raw_input("enter your parameters")


external file (cmd.txt):

"abc def" xyz

python pgm.py < cmd.txt

Thank you for the tip. It works:

import ctypes

p = ctypes.windll.kernel32.GetCommandLineA()
print ctypes.c_char_p(p).value

Now I only need to split the whole command line into 3 parts and get
the last one.

Thanks for all your input.

Well, FWIW, it is exposed by pywin32:

<code>
import win32api
print win32api.GetCommandLine ()

</code>

Better would be this code:

import ctypes
ctypes.windll.kernel32.GetCommandLineA.restype = ctypes.c_char_p
print ctypes.windll.kernel32.GetCommandLineA()
