in the spirit of sharing... this is a method I use frequently to run shell scripts. you can add a script to your product bundle (in the copy phase of the build) and then have the script be read and run at runtime. note: this code looks for the script in the privateFrameworks sub-path. warning: this could be a security risk for deployed products, but for our in-house development it is an easy way to customize simple things (like which host to rsync to...) without re-compiling the application, but just editing the shell script in the bundle.

//------------------------------------------------------
-(void) runScript:(NSString*)scriptName
{
    NSTask *task;
    task = [[NSTask alloc] init];
    [task setLaunchPath: @"/bin/sh"];

    NSArray *arguments;
    NSString* newpath = [NSString stringWithFormat:@"%@/%@",[[NSBundle mainBundle] privateFrameworksPath], scriptName];
    NSLog(@"shell script path: %@",newpath);
    arguments = [NSArray arrayWithObjects:newpath, nil];
    [task setArguments: arguments];

    NSPipe *pipe;
    pipe = [NSPipe pipe];
    [task setStandardOutput: pipe];

    NSFileHandle *file;
    file = [pipe fileHandleForReading];

    [task launch];

    NSData *data;
    data = [file readDataToEndOfFile];

    NSString *string;
    string = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding];
    NSLog (@"script returned:\n%@", string);    
}
