Reading each item from a formatted file

Hi,
I have a file generated like this -

1. Fire SQL and store the formatted output in a temp file

echo "select path, empid, age from emp_tbl" | /usr/sql emp_db 2 > count_file | grep vol > tempFile

2. The tempFile looks like this after the above statement

/vol/emp1 0732 25
/vol/emp2 0745 26


My requirement is to read each "column" of this temp file ? How can I do that ? Smilie

Thx a lot in advance. Kindly help.

Use cut like this:

Code:
cut -d ' ' -f 2 tempFile

produces:

Code:
0732
0745

Something like this:
Code:
while read column1 column2 column3
do
 # do something with $column1
 # do something with $column2
 # do something with $column3
 .
 .
done <  tempFile

Try this :

Code:
awk '{print $2}' tempFile

$2 - Indicates print the second field of tempFile. Space is default delimiter.
