這個問題在這里已經有了答案： 將 bash 變數傳遞給 jq （9 個回答） 3 天前關閉。
我有一個 bash sript pull.sh，其中一個引數是一個人的 github 昵稱。我想計算用這個昵稱發出的所有拉取請求的數量。我在命令列中以這種方式選擇 pr：
curl -s https://api.github.com/repos/owner/repo/pulls?"state=all&per_page=100" | jq '.[] | select(.user.login=="nickname") | .user.login'
這作業得很好。但是我如何計算選擇了多少值？
在 bash 我正在嘗試這個：
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"
但它不列印任何東西。
另一個問題是 repo 中的拉取請求數量遠大于 100。我需要搜索所有這些請求。我該怎么做？

uj5u.com熱心網友回復：
您可以使用jq --arg ...選項傳遞值并構建一個有效的jq請求，如下所示：
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
更新
完整jq解決方案：
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'
