Hi all,
This is what I type in bash | Code: | | startx `which wine` "C:\\Program Files\\Ubisoft\\Prince of Persia Warrior Within\\PrinceOfPersia.exe" -- :1 |
and this is what output I get | Code: | xauth: creating new authority file /home/ishanarora/.serverauth.654

Notice this line wine: cannot find 'C:\Program'
Basically startx broke my client arguments into more than 1 where ever it had spaces. Am I missing something here? Any help is appreciated. Thanks. |

Before each space in the argument, put a backslash \ just like you did before each directory end. This means that it'll use the explicit character located right after the backslash (even a space).

didn't work. As far as I know anything in qoutes is taken as is. Without qoutes '\ ' means a space. |

Sorry, I just now realized what you were trying to do.
Try giving the absolute path to the .exe file. Something along the lines of "~/.wine/drive_c/Program Files/Ubisoft/Prince of Persia Warrior Within/PrinceOfPersia.exe" -- :1
C:\ is a virtual directory which doesn't actually exist on the computer. The real directory is usually drive_c or whichever drive you set it as. Wine just reads the directory AFTER it's running as C:\.

I have tried it all.
It is clear from the output, that startx is splitting arguments at whitespaces. Btw, wine supports Windows like paths, i.e. | Code: | | wine "C:\\Program\ Files\\Ubisoft\\Prince\ of\ Persia\ Warrior\ Within\\PrinceOfPersia.exe" |
works.
Let me state it a little more generally. I want to run a program with arguments that contain spaces. This is easy, as I can put the agruments in qoutes and spaces are included. Now I want to run this program with same arguments, but as a startx client. Here startx doesnt seem to respect the spaces in arguments. Please help. |

Try to put some single quotes instead of double one.
I encounter quite the same problem because if the line is "interpreted' multiple times, your backslash+space will disappear at the first one, so the second interpretation stop at the first space.

That didn't work either. First I tried this | Code: | | startx `which wine` 'C:\\Program Files\\Ubisoft\\Prince of Persia Warrior Within\\PrinceOfPersia.exe' -- :1 |

So I understand single qoutes preserve double backslash. So I tried this | Code: | | startx `which wine` 'C:\Program Files\Ubisoft\Prince of Persia Warrior Within\PrinceOfPersia.exe' -- :1 |
and this is the output I got | Code: | xauth: creating new authority file /home/ishanarora/.serverauth.1838

Which is the same as the original problem.
Btw I did mention before that this has nothing to do with anything but startx. So you people could give it a try using any program that takes arguments with spaces. It would be nice if you tried your solutions before submitting them here, since this would save the time it takes me to reply 
And if you do try it yourself, remember that startx requires you to pass the full path pf the client executable. |

Just a reference to what all I have tried so far.
No qoutes (using backslash)
Double qoutes
Single qoutes
Single qoutes in double qoutes
Double qoutes in single qoutes
And a lot of them. It seems like startx intensionally breaks the arguments at spaces. I looked up the code for startx and I found that it uses xinit internally. I am not much of a bash coder so I dont know if the argument splitting happened in startx or xinit. And no xinit is not coded in bash so it is not even readable. And I dont dare to see its code. Can someone try the same with xinit and tell me if it is a problem with xinit or startx |

Ok the problem is with startx. I just checked it. This is what I tried. I created a bash script
| Code: | #!/bin/sh
clientargs="$@"
echo $clientargs |
And this script also has all the problems of startx. Try this script with an argument "a a" and you will get an output "a a".
Anybody knows how to tackle it the right way in bash |

The only way to prevent the shell splitting at spaces in is to change IFS. So you might want to try | Code: | | IFS='' startx `which wine` "C:\\Program Files\\Ubisoft\\Prince of Persia Warrior Within\\PrinceOfPersia.exe" -- :1 |
However, be warned that changing IFS is a good way to break unexpected things in any shell code, so don't blame me if this command has unexpected side effects, and startx formats your harddisks instead...
Edit: It is more compatible to use `command -v wine` instead of `which wine` |

Doesn't seem to help. I'll try to dig a little up later on. For now I am using xinit which works perfectly, but I am missing out on default parametrs startx passes.
Thanks for the suggestion about command -v |
