bash - Touch files from Z->A with a delay -

-

I have to touch several files in one directory in reverse alphabetical order, with 1 second delay, the name of these files is empty There are places I have tried to do this:
LS | Sort-R | Tr '\ 012' '000' | Xargs-0 touch

and this: 

  #! / Bin / bash $ i (ls -r) for; Touch "$ i" has slept

But first it makes it very fast and I do not get what I want (to display files in my device), and The second place does not handle the vacancy.

Any thoughts?

EDIT: Sorry, I forgot to add that it would be better to make it as fast as possible, wait 1 second between the files, and I have 60+ files, I have 1 minute Sorry to not wait for more than trouble.

read will be read in one line at a time: 

  LS-R | While reading FILE; Alternatively, you can mess with the  $ IFS  variable so that only new lines can separate items in . I do not have the syntax, spaces or tabs in the list:  
  $ for FILE in $ (ls -r) = $ '\ n'; Touch "$ FILE" sleep 1  
 
 (Panoramas were added so that  $ IFS  should be restored later.If you forget and it is a non- Set to standard value), 
 
 Anyway, you can also leave sleep by using  touch -t  to set a specific timestamp, rather than doing it It looks more difficult, however, so I will leave another daring responder: -)

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
