sed with standard input not working
I am trying use sed to replace a string in a file with input string passed, but it is not replacing the string. instead it replace as $1. Please find below the code.

Code:
echo $1
sed -i.$now "s/http.*.myservice.*.war/$1/" tempfile.xml

I am running above code as below
Code:
myscript.sh ReplaceString

Output getting as
Code:
echo ReplaceString

but in output file tempfile.xml, value replaced as $1 but I am expecting a string ReplaceString.

Code:
$1

It is been solved. I found the replace text with special char. So I added escape char and it solved.
