how to write loop in batch

Hello all,

I want to write a loop in Batch, the idea was written in C.
//------------------------
for(par0=0.1;par0<1;par0=par0+0.1) {
command1 par0 par1;
command2 par0 par2;
command3 par0 par3;
}
//------------------------

//the par is parameter for command

How to change it to Batch(I use NT), thanks!

Regards,
Davy

NT's batch mode has no floating point support, but this is better than nothing:

@echo off
for /L %%X in (1,1,9) do (echo command1 0.%%X par1) & (echo command2 0.%%X par2) & (echo command3 0.%%X par3)

You can remove the "echo" strings later.

From the command prompt, try typing "help for"

I'm using Win2k. Maybe NT is similar.

Hi

And for unix/linux sh...

for i in `command generats a sort of listing`
do
//now $i is refer to i-th item in the generated list. do what you want
done

example:

for i in `ls *.pdf`
do
pdf2txt $i $i.txt
done

tnx
