I want to replace IP dynamically but somehwo sed is placing word $IP instead of actual value.

 IP=10.50.33.44
 PORT=5774
 sed -i~ 's/https:\/\/10.11.12.13:8443/https:\/\/$IP:$PORT/g' abc.txt

Can you help me out in getting the correct value?

    Use double quotes" for variable expansion:

     sed -i~ "s/https:\/\/10.11.12.13:8443/https:\/\/$IP:$PORT/g" abc.txt

    and as @Joachim said, use different delimiter. For example,

     sed -i~ "s;https://10.11.12.13:8443;https://$IP:$PORT;g" abc.txt
