疎通待ち

shimizukawa.icon人類はいつまでshell scriptに頼るのだろうか...

curl -w でデバッグ表示付き

code:bash

echo -n "Waiting for HTTPS status 200 ..."; while ! curl -q https://site/ -w '%{http_code}\n' -f -s -o /dev/null; do echo -n "."; sleep 1; done; echo "ok"

code:console

Waiting for HTTPS status 200 ...502

.502

.200

python3

code:bash

echo -n "Waiting for HTTPS status 200 ..."; while ! python3 -c "exit(__import__('urllib.request').request.urlopen('https://site/').status!=200)" >/dev/null 2>&1; do echo -n "."; sleep 1; done; echo "ok"

もうちょっと良い書き方ないかなあ

Makefileでecho -nが使えない場合は/bin/echoを使う。
