How to count amount of pull request made by user?

Question

I have bash sript pull.sh with one argument is github nickname of a person. And I want to count amount of all pull request which was made with this nickname. I select pr this way in command line:

curl -s https://api.github.com/repos/owner/repo/pulls?"state=all&per_page=100" | jq '.[] | select(.user.login=="nickname") | .user.login'

And this work well. But how can I count how much values was selected?

In bash I am trying this:

amount_of_pr=$(curl -s https://api.github.com/repos/owner/repo/pulls?"state=all&per_page=100" | jq '.[] | select(.user.login=="$1") | .user.login')
echo "$amount_of_pr"

But it doesnt print anything.

Another problem is that amount of pull requests in repo is much bigger than 100. And I need to search through all of them. How can I do it?

Example of curl output

@Cyrus yes, thank you, but still if I do select(.user.login=="$1") It prints nothing, but I if I try this select(.user.login=="someone_nickname") it works. How can use parametr to select? — Vivern202, Nov 14 '21 at 10:22

You could use jq --arg ... option to pass values and build a valid jq request like this:

curl -s \
  -H "Accept: application/vnd.github.v3+json" \
  --url "https://api.github.com/repos/datamove/linux-git2/pulls?state=all&per_page=100" \
| jq \
  --arg user_login "$1" \
  '.[] | select(.user.login==$user_login) | .user.login' \
| wc -l

UPDATE

Full jq solution:

curl \
  -s \
  -H "Accept: application/vnd.github.v3+json" \
  --url "https://api.github.com/repos/datamove/linux-git2/pulls?state=all&per_page=100" \
| jq \
  --arg user_login "$1" \
  '[select(.[].user.login == $user_login)] | length'

Thank you! How this script will be modified if there more than 100 pul-repuests? – Vivern202 Nov 14 '21 at 11:20
You can't retrieve more than 100 pull-request one time but you can select the page with `&page=n` where `n` is a number. By default `n` is equal to `1` – Arnaud Valmary Nov 14 '21 at 16:07
