Can batch processing achieve sequence numbers? - China DOS Union Forum

For example, to generate sequences like 1, 2, 3... 999, how to do it?

Requirements: Do not use commands under XP.

"Requirement: cannot use commands under XP. " How to understand this? That is, only use DOS's COMMAND?

If that's the case, using WAIT and COUNTER should be possible. Idea: Refer to PLC programming to use "timer and counter relay" to achieve long delay mode, timing drive, counting step activation.

But BATCH FILE may have a simpler way. Please discuss everyone:>

It can be done with the third - party tool Strings.com.

Re bush:

Recently, there seem to be many problems that need to be solved under MSDOS/Win9x_COMMAND, which is very similar to my situation three years ago, and I feel like meeting an old acquaintance from afar.

Regarding generating sequence numbers, I remember mentioning it in a past reply, but it's hard to find now; if I have time, I will organize it into my " An Unusual Batch Programming" topic, please wait.

Now provide a relatively similar code , which uses double loop nesting to generate and process sequence numbers with and without prefix 0 between 0-9 and 10-99.

Change the file name to 001.txt 010.txt...100.txt

Thanks willsort, my problem has been solved!

The cause is like this. Got a download package of a website, came back and saw it was incomplete. Had to check to know which files were missing, a thankless task! And these file names are composed of sequence numbers, like this: www.xxx.com/xxx/file1.html、www.xxx.com/xxx/file2.html……www.xxx.com/xxx/file389.html.
Fiddled around for a long time and came up with some batch processing solutions. The idea was to generate sequence numbers first and then use exist to judge.

Before starting, for safety, changed.html to.htm
a.bat

b 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 31 32 33 34 35 36 37 38

;Actually the first batch processing file was also generated with batch processing.
b.bat

@echo off
for %%a in (1,2,3,4,5,6,7,8,9) do call c node%%a.htm
:redo
if "%1" == "" goto end
for %%a in (0,1,2,3,4,5,6,7,8,9) do call c node%1%%a.htm
if errorlevel 2 goto end
shift
goto redo
:end

c.bat

@echo off
if not exist %1 echo %1 >> urls.lst
echo on

The finally obtained urls.lst is the needed file. Hehe, then batch process to download ~

It's simple under CMD, just one statement can do it.


for /l %i in (1,1,389) do @if not exist file%i.html echo.file%i.html>>urls.lst

For downloading things like this, I usually use curl or wget, and then batch organize, which is very convenient.
