Hello there
I was wondering why this piece of code doesn't work by itself on my mac ?


NSTask *task;
task = [[NSTask alloc] init];
[task setLaunchPath: @"/bin/bash"];

NSDictionary * environment = [NSDictionary dictionaryWithObjectsAndKeys:@"localhost:0.0",@"DISPLAY",nil];
NSArray * arguments = [NSArray arrayWithObjects: @"-c", @"/usr/ X11R6/bin/xhost + && /sw/bin/nedit", nil];
[task setEnvironment: environment];
[task setArguments: arguments];
[task launch];

Running "xhost +" makes the baby Jesus cry - and opens up a potential major security hole. Don't use it.


Also, you can't assume that the correct DISPLAY is :0.0 - what if more than one user has X11 open? (Multiple users will get different DISPLAYs.)
