Translate a Shell script into Windows Batch file

[T2ioTD]

Hi

Would you please assist me to turn this shell script (kindly written by fmw42) into a batch file:

cd
cd desktop/test1
imgname="rose"
arr=(`ls ${imgname}*.png`)
numimg=${#arr[*]}
num=`echo "scale=0; $numimg/2" | bc`
for ((i=0; i<num; i++)); do
j=$((2*i+1))
k=$((j+1))
convert ${imgname}$j.png ${imgname}$k.png +append ../test2/${imgname}${j}_${k}.png
done
cd

My intent is to drag and drop a number of images (or a folder containing images? this still confuses me)
into the batch file, so that images are joined two by two (side by side).

Note: i will be absent for a couple of days, so please do not be offended if I do not reply promptly...

I would rather write a Fortran creating the series of DOS commands, but try the newsgroup alt.msdos.batch

I put myself to the problem: create the batch assoctab.bat with

for /L %%a in (1, 1, %1) do (
(set /a ileft="2*%%a-1")
(set /a iright="2*%%a")
call convert rose%%ileft%%.png rose%%iright%%.png +append tulip%%ileft%%_%%iright%%.png)

Type assoctab <number of initial png files>

Hope you will be able to adapt it.
