Thansk Raja and Vidyadhar,

I am getting the ambigous redirection of file error now for

Code:
 
NEWFile_$(date +%F-%T).hrb

I think it is not redirecting the changes in the new file

Code:
sed -e "s/URL/$Url/g" -e "s/port/$Port/g" Monitor_Template.hrb  >> NEWFile_$(date +%F-%T).hrb

and it is creating 0kb file in result.

For your below code Raja,

Code:
 
for line in $(cat $HSFILE)
do
  Url=$(echo $line |  awk -F":" '{print $1}')
  Port=$(echo $line |  awk -F":" '{print $2}')
  cat Monitor_Template.hrb | sed -e "s/URL/$Url/g" -e "s/port/$Port/g" >> NEWFile_$(date +%F-%T).hrb


I need each varaible from the input file like URL 1 to replace first and port 1 second.
So my loop should run for three time and create three files after replacing the mentioned values in the input file.

Hi rajamadhavan

I tried your snippet of code

Code:
echo $line|awk -F":" '{print $1" "$2}'|read Url Port

if I echo $Url and $Port, It is not showing anything on the console. Value in file is getting replaced by null.
