Have used NSTask to execute Terminal commands before but having trouble with gzip. I'm guessing my arguments are not set up correctly. Anyone see what's wrong in this example?

include "Util_FileDirectory.incl"

BeginCFunction
void ZipFile( CFStringRef inPath )
{
	NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
	NSTask *task = [[[NSTask alloc] init] autorelease];
	[task setLaunchPath:@"/usr/bin/gzip"];
 NSString *outPath = [[[NSString alloc] initWithFormat:@"%@.zip",(NSString *)inPath] autorelease];
	[task setArguments:[NSArray arrayWithObjects:@"-c",@"-P",@"rotide",(NSString *)inPath,@">",outPath,nil]];
	[task launch];
	[pool drain];
}
EndC
toolbox ZipFile( CFStringRef inPath )

dim as FSRef ref
dim as CFStringRef path

long if ( files$( _FSRefOpen,,, ref ) )
fn FD_FSRefCreatePath( @ref, @path )
ZipFile( path )
CFRelease( path )
end if

RunApplicationEventLoop()
