Code: (Objective-C)

#import <Foundation/NSObject.h>
#import <Foundation/NSString.h>
#import <Foundation/NSFileManager.h>
#import <Foundation/NSProcessInfo.h>
#import <Foundation/NSArray.h>
#import <Foundation/NSAutoreleasePool.h>

/* basename */

int main (int argc, const char * argv[]) {
    NSAutoreleasePool				* pool = [[NSAutoreleasePool alloc] init];
	NSFileManager					*fm = [ NSFileManager defaultManager];
	NSProcessInfo					*proc = [NSProcessInfo processInfo];
	NSArray							*args = [proc arguments];
	NSString						*name, *basename, *basenameFinal;
	
	/* check usage */
	
	if ( args.count != 2)
	{
		NSLog(@"Usage:%@ basename NAME[SUFFIX]", [proc processName]);
		return 1;
	}
	
	
	name = [args objectAtIndex: 1];
	basename = [name lastPathComponent];
	basenameFinal= [basename stringByDeletingPathExtension];
	NSLog(@"%@", basenameFinal);
	[pool drain];
    return 0;
}

Works for me...I suppose you could eliminate the second variable by stringing the commands, but I'm not sure if that will introduce readability problems with larger programs.

Code: (Objective-C)

	basenameInput = [args objectAtIndex:1];
	basenameFinal = [[basenameInput lastPathComponent] stringByDeletingPathExtension];
