On Ubuntu server 16.04.6, I am using Curl (v. 7.47.0) to test my web-server and network components.
Using the -: option (also known as --next), I keep the TCP connection open, and send multiple HTTP requests to my server, for example:
curl -s -o /dev/null -: -s -d "data" -:
Now, assuming I would like to send exactly the same HTTP request 3 times, I would use:
curl -o /dev/null -: -o /dev/null -: -o /dev/null
My question is: is there a way to repeat this HTTP request to the same uri with same options "n" amount of times without adding -: -o /dev/null over and over again?
For example, sending 100 of the same HTTP requests using the same TCP connection without writing -: -o /dev/null 99 times?

You can use xargs for this purpose like this:
for i in {1..100} ; do
echo ' -o /dev/null -:'
done | xargs curl -s
Please, note that xargs will not produce a command larger than 2,088,616 characters in my system. You can determine this maximum length in your system by running xargs --show-limits in your system.
