Solve : copy con in batch? |
|
Answer» Alright, what I'm trying to do is create a batch file that'll create the text files I list (the color change is to let me know when it's done at a quick glance). I'm making a sort of calendar, so the files looks like so: Alright, what I'm trying to do is create a batch file that'll create the text files I list (the color change is to let me know when it's done at a quick glance). I'm making a sort of calendar, so the files looks like so: When you say it freezes after the first Copy Con command Copy is waiting for input from the Console (keyboard) to write to the first file. When the input is complete CTRL+Z is necessary to terminate that Copy and continue. No input no continue.. why do you need to use a copy con? Quote from: ghostdog74 on July 01, 2007, 03:32:34 AM why do you need to use a copy con? I was wondering that. I dunno... I thought I'd try copy con because it's new to me. I just need something to create all the files, preferably without a break between commands. Know a better command keyword to use? Thanks for clearing up how copy con works.Quote from: Computer_Hopeless on July 01, 2007, 06:40:03 AM I just need something to create all the files, preferably without a break between commands. Know a better command keyword to use? echo sounds like the command to use. What are the files supposed to contain? If it is OK for them to be empty you could use echo like this echo. > 7-1.txt echo. > 7-2.txt etc Yeah, that'd work. Thanks. Just for the sake of doing more work to try to avoid doing work in the future, what should I use if I wanted to put in, for example, a list of the hours of the day in half hour increments with no break or prompt between commands?Quote from: Computer_Hopeless on July 01, 2007, 06:58:39 AM Just for the sake of doing more work to try to avoid doing work in the future, what should I use if I wanted to put in, for example, a list of the hours of the day in half hour increments with no break or prompt between commands? What, you want to FILL a folder up with 48 empty files which are named after the hours and half hours of the day? I guess something like this would work. I assuming the 24 hour system. If you need a 12 hour system with am & pm then I am sure you can work out what changes are needed. echo. > 00-00.txt echo. > 00-30.txt echo. > 01-00.txt [snip] echo. > 23-00.txt echo. > 23-30.txt (You cannot use a colon in a file name) However, like the other people who have learned to code before you, you will soon be realising that it is a pain in the @ss to keep typing the same thing over and over again, ALSO it makes code which experienced programmers smile at, which is the point at which one learns about one of the fundamental programming constructs, the loop. Loops exist in batch programming language. Here is one which will do the same job as the 48 line batch I outlined above. Code: [Select]@echo off for %%H in (00 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23) do ( echo. > %%H-00.txt echo. > %%H-30.txt ) The FOR command could be shortened considerably but I left it like that on purpose so it illustrates the principle better. That's pretty useful to know, but I was asking about having the hours within each date named text file.start a file with >, then add to it with >> echo 00-00 > 7-1.txt echo 00-30 >> 7-1 txt [snip] echo 23-00 >> 7-1.txt echo 23-30 >> 7-1.txt echo 00-00 > 7-2.txt echo 00-30 >> 7-2 txt [snip] echo 23^:00 >> 7-2.txt echo 23^:30 >> 7-2.txt [etc] To fill in the blanks is a trivial exercise which I shall leave for you to complete... Such a batch would be 48 x 31 lines long... 1488 lines... but I expect you can think of a way around that... you can add the time programmatically...here's a vbscript Code: [Select]Dim myTime, objFSO, startTime,count,FilePrefix,objFile Set objFSO= CreateObject("Scripting.FileSystemObject") startTime="00:00:00" count=1 FilePrefix="7_" myTime=FormatDateTime(DateAdd("n",30,CDate(startTime)),vbShorttime) Set objFile = objFSO.CreateTextFile(FilePrefix&CStr(count)&".txt",True) objFile.Write(myTime) objFile.Close count=count+1 Do while myTime <> "00:00" myTime=FormatDateTime(DateAdd("n",30,CDate(myTime)),vbShorttime) Set objFile = objFSO.CreateTextFile(FilePrefix&CStr(count)&".txt",True) objFile.Write(myTime) objFile.Close count=count+1 Loop Thanks again for all the help. When using the FOR command, how would you set a range of numbers within the set, instead of listing them all out? What EXACTLY is and how exactly do I use a "vbscript"? I'll wiki it in the meantime. This is my new batch file, loopcal.bat: Code: [Select]color 02 for %%D in (1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30) do ( echo. > 7-%%D.txt ) for %%H in (1 2 3 4 5 6 7 8 9 10 11 12) do ( echo %%H am >> 7-??.txt echo %%H pm >> 7-??.txt ) color 0a It'll create the files, but when it's supposed to print the hours in each one, it tells me: The filename, directory name, or volume label syntax is incorrect. Know where I messed up?Quote from: Computer_Hopeless on July 01, 2007, 09:37:31 AM When using the FOR command, how would you set a range of numbers within the set, instead of listing them all out? FOR /L %%parameter IN (start,step,end) DO command start : The first number step : The amount by which to increment the sequence end : The last number command : The command to carry out, including any command-line parameters. %%parameter : A replaceable parameter: in a batch file use %%G (on the command line %G) So (20,-5,10) would generate the sequence (20 15 10) (1,1,5) would generate the sequence 1 2 3 4 5 Quote What exactly is and how exactly do I use a "vbscript"? I'll wiki it in the meantime. Never use 'em. Scripts for Windows Scripting Host. (Wiki or Google that also) Quote This is my new batch file, loopcal.bat: 1. There are 31 days in the month of July. 2. You need to nest the loops, which is going to bring us to the topic of delayed variable expansion. 3. Those question marks in "echo %%H am >> 7-??.txt" are errors and will generate the message you saw. Can I just ask, forgive me if I am wrong, but is this your homework? If this is a homework project, I predict your teacher will know for sure you didn't write this, so you won't dare submit it, and if it's for your own amusement, I apologise for my nasty suspicions and invite you to pore over this and attempt to puzzle it out by visiting some of the batch tutorials and guides that are plentiful on the web. It's just that many many batch questions start off "I was just wondering [yeah, right!] how to do xyz in a batch file", and there follows a suspiciously detailed and arbitrary specification for some project which nobody would dream up for themselves in a month [28,30 or 31 days!] of Sundays (AM/PM, half hourly intervals, etc etc), which smells strongly of "a teacher wrote this". Forgive my suspicious mind if I have got it all wrong, and in that case please accept the following gift... This is a hacked-together quick and dirty batch file. It's not a definitive solution, it's just how I would choose to make a calendar in a batch. It could be extended to do a whole year, or any month as required, to know which months have 30 or 31 days, even to decide if February has 28 or 29 days that year.

Thank you again for the help. I'll mess around with what you've given me and get back to you in a while. This loop tool (the only loops I'd ever used before were on the school calculators) will be exceptionally useful in the future. Thanks. |
