parsing a variable

g_rohit7 · #1 (**permalink**) 03-16-2009

Hi,

I want to get an input from user and parse the input. The legal characters allowed in the input are alnum(a-zA-Z0-0), . , -
Also the first and las characters must be alnum only.

e.g
if the input is abc.ghh-sok.com then the script should return correct, and if the input is like abc#.def.com-fhj then the script should return incorrect.

I am new to scripts so help me with this problem of parsing?

Hello there,

I think the following KornShell script can do the job.

Code:

#!/bin/ksh

print -n "Enter your value: "
read USER_INPUT

if [[ $USER_INPUT = +([a-zA-Z0-9])*([a-zA-Z0-9.-])+([a-zA-Z0-9]) ]]
then
    print "Correct"
else
    print "incorrect"
fi

Regards,
