Please find attached the script where i am trying to validate first number should be 155 and if true then checks :0.0 and checks for a 2 digit value and sets the DISPLAY variable. Now this only works for two digit upto :99.0 but i need this to be working even for a four digit display like from :1.0 thru :1000.0. Please help me with this script.

Thanks
Joe.

It should be sufficient to numerically evaluate the first IP octet as 155 and the screen number as greater than or equal to 10.

verify_DISPLAY () {
if [ ${1%%.*} -eq 155 -a ${1##*:} -ge 10 ]
then
return 0
fi
echo 'DISPLAY is NOT valid'
return 1
}
