Hi all..

I am trying to match a number with atleast 5 digits but following is not working

echo 123456 | grep '\d{5,}'

try that instead
Code:
echo 123456 | grep '[0-9]\{5,\}'

Grep uses standard regex's unless told otherwise - that's a perl regex. What you want can also be done with character classes. See the manpage.
