That one always drives me nuts. Why fork/exec for such a heavy process
for something bash can do itself:
cat $file | while read column1 rest; do
echo $column1
done
Or if you need the data in the calling shell's context:
while read column1 rest; do
# the goodies are in $column1
done < <(cat $file)
Probably a dozen other ways to do it too.
