I suppose those are some reason to do it but when considering readability it's worth considering how convention can make things easier to recognise/read. I think there are many reasons why putting it afterwards is clearer.. A)The convention most people use is putting it afterwards.. the first time I...

I am very sorry to hear that.

His technical posts were of great benefit.

He will be missed.

I don't think he understood you penpen. His reply would have been more descriptive about his problem. Hmm not sure why I didn't get notified of the reply to this thread at the time, but was just checking back on this topic now to refresh my memory on penpen's findstr workaround, and saw that there ...

thanks

Hi How can I quickly write a large file where each line has the string "aaa"? this method is slow I let it run for about 20 seconds and stopped it 'cos it was slow and it wrote maybe 20,000 lines far from 200,000 C:\blah>for /L %f in (1,1,200000) do @echo aaa >>abigfile1.txt I could write a program ...

thanks

it seems to create two command processes pause>nul|set /p=sdf seems to be creating two cmd processes So if I open a cmd.exe window, I have one showing in task manager then I run that and I get 3 running. So it created two. why? I notice that pause or pause>nul, doesn't create a cmd process. So it se...

I've often heard that pipes create a new instance of cmd..

I don't see it though

If I go to e.g. the windows directory and I do dir /p | more, then I don't see a new cmd.exe instance appear in task manager.

i'm also interested in when that has ramifications that some might not foresee.

thanks

Thanks, that was very informative.

In what programming language(s) have you had the experience of creating pipe objects?

Was the environment *nix or windows, and were there big differences?

thanks.. (I think I figured out exactly what's going on but mid post.. though i'm still not 100% if my conclusions are totally correct) i'm trying to figure out what's going on with this command you have that works.. Z:\>type testfile | grep "." | (head -n 1 & findstr /v "^")...

What methods are there for me to display the first n lines of a file, it seems there is a bug in piping to gnuwin32 head and gnuwin32 sed http://www.dostips.com/forum/viewtopic.php?f=3&t=7480 (I can use them without pipe as then they won't run into the bug, but i'd like commands that I can pipe ...

So the for statement generates a file.. Grep is like the windows find command. The "." is not current directory, it's a regex pattern (like findstr uses). It means any character I think i've narrowed it down to head rather than grep or some combination of head and grep.. Though interesting...

further to my last post, here's how you do it in a nutshell using 3rd party tools of sed and grep C:\blah>tasklist>a.a C:\blah>del b.b C:\blah>for /f "tokens=5 delims= " %f in (a.a) do @echo %f >>b.b C:\blah>sed "s/,//" b.b>c.c C:\blah>grep -P "^\d+" c.c>d.d C:\blah>set...

well, tasklist will list chrome.exe 6604 Console 1 341,108 K chrome.exe 4220 Console 1 74,548 K chrome.exe 7256 Console 1 52,876 K chrome.exe 8084 Console 1 35,156 K vncviewer.exe 8056 Console 1 23,904 K It's possible an administrative cmd prompt lists more.. one would have to check.. I am not sure ...
