Hi All,
I am new to this shell scripting world. Struck up with a problem, can anyone of you please pull me out of this.
Requirement : Need to get the index of a substring from a parent string
Eg : index("Sandy","dy") should return 4 or 3.
My Approach :
I used Awk function index to achieve this
when i excecute this in command line
awk 'BEGIN { print index("Attempting to connect to ipaddr: 127.0.0.1 IllegalUrl_110707092804.txt Succeeded with no errors.","Succeeded with no errors") }'
72
if gives me correct output which is 72
but in shell script it always returns 0.
$a="Attempting to connect to ipaddr: 127.0.0.1 IllegalUrl_110707092804.txt Succeeded with no errors."
$b="Succeeded with no errors"
echo "`awk 'BEGIN { print index($a,$b) }'` "
Can anybody please tell what is the problem or suggest an alternate approach.
Many Thanks,
Sandeep
