Corona688 posted an elegant solution for your original specification, that gets rid of excess spaces but it would not work right for the second sample.

In addition to what rbatte posted, another way to get rid of the leading space after the comma would be:

Code:
while IFS=, read field1 field2 
do
  echo "${field2# }" 
done < input.txt > allINeed.txt

--
Note: this only works if there are exactly two fields, if there can be more you would need to add a third variable to the read command..
Code:
while IFS=, read field1 field2 field3
do
  echo "${field2# }" 
done < input.txt > allINeed.txt

--
Another note, to get consistent results independent of input, the safest approach would be to use printf, rather than echo
Code:
printf "%s\n" "${field2# }"

Thank you all so much for your help. I reviewed a few of these, and I think that the most efficient way of doing this is using:

Code:
cut

# 10  
If you want to catch col#2 and trimm the leading spaces
Code:
awk -F', *' '{print $2}' input.txt
