You need to do it one number at a time.
for i in `seq -f '%04.f' 1 999`
do
montage -geometry +4+4 {a,b,c,d}_$i.jpeg montage$i.jpeg
done
I'm not sure about the best way to do the _ to A series though.
A simplish way would be:
for file in a*
do
num=`expr "$file" : "a\(.*\)\.jpeg"`
montage -geometry +4+4 {a,b,c,d}$num.jpeg montage$num.jpeg
done
but this preserves the _->A sequence, so you'll end up with
montage_0001.jpeg through to montageA999.jpeg.
If you want to replace the _->A with 0->whatever you need a tr line in
there:
for file in a*
do
num=`expr "$file" : "a\(.*\)\.jpeg"`
outnum=`echo $num | tr '_A' '01'`
montage -geometry +4+4 {a,b,c,d}$num.jpeg montage$outnum.jpeg
done
Use your collating sequence, as I don't know what it is ('_' comes
after 'A' in ASCII).
