echo into columns
hello there,
Thank you for any help you may offer.
I have the fallowing command

echo `ls -1 /Volumes/ximage2/$line/images/ | wc -l` $line

which give me the number of sub directories followed by the name of the parent directory of interest to me.

it ends up looking like this

1 W1GS56158
8 W1GS61404
11 W1KG1132
2 W1KG606
1 W1KG802

I would like it to seperate the results into columns instead so that the w's always align
