I have the following code trying to calculate how much time it takes in milliseconds to build a docker container. However I am facing syntax error and command not found issue, running bash script bash pipeline.sh

#!/bin/bash
echo 'Initiating pipeline'
cd /home/switch-approach/server-c
start=date+'%s%3N'
sudo docker build -t server-c .
end=date+'%s%3N'
echo "duration: $((duration=end-start)) seconds."
Retrieving error date+'%s%3N' command not found 
operand expected syntax error start

You want start=$(date ...) (and also for end). – muru Feb 08 '21 at 11:19
@muru thanks for your help I am still receiving date command not found error. the syntax error is gone – user1566490 Feb 08 '21 at 11:22
put a space between date command and plus parameter – D'Arcy Nader Feb 08 '21 at 11:25
@D'ArcyNader, thank you so much its working perfectly fine now, didn't realised that it was a silly mistake. You save my day – user1566490 Feb 08 '21 at 11:26
