bash - How to read from multiple files in one loop? -


i need read multiple file in 1 loop. have 1 file x coords, 1 file y coords , 1 file chard on coords...

for use paste put these files , in while loop use cut separate them this:

cat $file | while -r line;     y=$(echo "$line" | cut -d\  -f1)     x=$(echo "$line" | cut -d\  -f2)     char=$(echo "$line" | cut -d\  -f3) done

but problem it's slow (calling cut again , again)..

how should have in each loop proper values in $y, $x , $char while speeding things up?

thanks in advance ^_^

i'm not sure how without paste, can avoid cut assigning variables in 1 read:

while read -r x y char;     echo "x = $x; y = $y; char = $char"; done < "$file"
