unix command line ...how to grep and show only file names that contain a string? -

-

I know I can find a string with this: 

  grep -n -d recurse 'Snoopy' * *

and then it displays each filename and example that contains the string, such as: 

  file / name. Txt: 23 Some snip files here: file name 2 test: 59 other snop file / name2.txt: 343 some more snopies etc ...

The problem is that with many incidents, The list is too large, how can I just show it the actual file name The front, including string, without duplicates and without incident?

Only: 

  file / name1.txt file / Name52.txt file / name 28293.txt

any help Thanks a lot :)

-l flag (or, BSD and GNU does both grep , - file-k-match ) do you want. From

to:

Write only the names of the files that are selected for the standard output, after every file is searched, the path name will be typed. If standard input is searched, POSIX locale will have the pathname of "(standard input)". In other local places, "standard input" can be replaced by some more suitable in those places.

Both BSD and GNU also explicitly guarantee that it will be more efficient (version says, "... grep searches for only one match , Unless a match is found, making searches potentially less expensive ", and" scanning will be closed on the first match. ") T know which grep < / Code> and which options are there, just type man grep on the shell and you want to get the manpage New.

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

-
We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
