I want to validate a String. If it is "Deepak Xavier" then it will a valid string.
But if the value "Deepak #&xavier" then it should be invalid. Please give me some commands. Iam using KORN shell. Thanx in advance.

Code:
#! /bin/ksh

NAME="Deepak Xavier"

if [[ "$NAME" == "Deepak Xavier" ]] ; then
echo "User Name valid"
fi ;

Here is a link to the Oreilly's Learning the Korn Shell

I suggest you read through that.

I have merged these two threads together because they are the same question.

Here is one way to verify that a string only has letters and spaces...
Code:
NAME="-Deepak #&xavier"
if [[ $NAME = $(echo "$NAME" | tr -dc '[A-za-z ]') ]]
then
   echo ok
else
   echo bad
fi
