Question

I am trying to send a request in curl and trying to insert current timestamp in the cookie

curl -v 'https://example.com'
-H $'cookie: ts=1601356520581'

How to insert the date +%s%3N in place of the hardcoded value?

If you are using a POSIX shell (sh, bash, zsh, etc), you can expand your command with the syntaxis $(command). For example:

curl -v "https://example.com" -H "cookie: ts=$(date +%s%3N)"
