Webif 文と test コマンド. 前提知識. if文では条件式に指定されたコマンドの終了ステータスを判定し分岐をしている。終了ステータスが0の場合に真となり、そうでない場合には偽となる; if []と書いた場合、if testと書いたことと同じ扱い([]はtestコマンドの略式) This checker script returns 0 if the conditions are insufficient, and 1 otherwise. (I realize this is backwards of convention, but I thought it would be easier for if statements.) Here is what I've tried, replacing the command with echo "ok": ./checker.sh && echo "ok". Echoes "ok" even though checker.sh returns 0. test ./checker.sh && echo "ok".
