使用此数据：
$cat file1
8.0 175.0
9.0 405.8
10.0 844.8
11.0 307.2
$cat file2
8.0 188.5
9.0 428.6
10.0 945.7
11.0 335.9
如何将这些合并到一起。我简单地尝试了paste的几种可能性：
$paste file1 file2
问题是我得到三列，其中中间的一列是从两个原始列合并而来的：
8.0 8.0.5 175.0
9.0 9.0.6 405.8
10.0 10.07 844.8
11.0 11.09 307.2
我想要的结果如下：
8.0 175.0 8.0 188.5
9.0 405.8 9.0 428.6
10.0 844.8 10.0 945.7
11.0 307.2 11.0 335.9
答案 0 :(得分：2)
你的文件有\ r \ n行结尾，所以第一行实际上是：
dos2unix在您的文件上运行sed -i.bak 's/\r$//'或- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
if ([mediaType isEqualToString:@"public.movie"]){
NSLog(@"got a movie");
NSURL *videoURL = [info objectForKey:UIImagePickerControllerMediaURL];
NSData *data = [NSData dataWithContentsOfFile:videoURL];
NSMutableURLRequest *request =[[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:@"http://dotstudioservices.com/labajaService/Service1.svc/videoempresa"]];
[request addValue:@"video" forHTTPHeaderField: @"Content-Type"];
[request setHTTPMethod:@"POST"];
NSInputStream *inputStream = [[NSInputStream alloc] initWithFileAtPath:[videoURL path]];
[request setHTTPBodyStream:inputStream];
[NSURLConnection
sendAsynchronousRequest:request
queue:[[NSOperationQueue alloc] init]
completionHandler:^(NSURLResponse *response,
NSData *data,
NSError *error)
{
if ([data length] >0 && error == nil)
{
NSLog(@"Request ended");
}
else if ([data length] == 0 && error == nil)
{
NSLog(@"Nothing was downloaded.");
}
else if (error != nil){
NSLog(@"Error = %@", error);
}
}];
}
[picker dismissViewControllerAnimated:YES completion:NULL]; }
。
