Re: Working directory

["Yury Sulsky" <ysulsky hotmail com>]

Err.. to answer my own question, no it isn't. Not even close.

So I realized that sending a patch without actually testing it is kind of 
stupid, so I did test it... and now I need help.

I figured out that I had to unquote the location of the executable before 
getting its directory, and that prepending a "cd <whatever>;" to a command 
doesn't work.

I tried using chdir() before it executing it instead, but that's no good 
either. Anybody have a clue how I could do this?

Thanks,
Yury
