In this shell script:

#!/bin/bash
i=0

printf "a a a\nb b b\nc c c\n" |
while read x
do
i=$[i+1]
echo "$x: ($i)"
done

echo $i

with this output:

a a a: (1)
b b b: (2)
c c c: (3)
0

How to I can get the value (3) for $i out of the while loop?

Many thanks

Is there a reason for using while instead of for?

for x in $(ls dir/)
do
.....
done

The one caution when dealing with path/filenames is spaces. That was
discussed not long ago and a few suggestions were given, mine being to
change the $IFS variable but others were suggested that also worked if
I recall.
