Question Date & NUmber Validation Query
Hi

Do you have any pointers how to validate numbers (not to contain alphabets and special characters) and date(MM/DD/YYYY) format.



I used following regular expression to validate integer, which is not working in the default shell:


nodigits="$(echo $testvalue | sed 's/[[:digit:]]//g')"

if [ ! -z $nodigits ] ; then
echo "Invalid number format! Only digits, no commas, spaces, etc." >&2
return 1
fi


Thanks
Alok
