使用未加密的错误代码目标文件使 git-crypt 退出

Question

我想写一个 git 钩子，如果我们的 .env 文件没有加密，提交将失败。但是，git status 总是以代码 0 退出。当文件未提交时，如何让此命令以错误代码退出。

# file encrypted
git-crypt status .env && echo "exit 0" || echo "exit 1"
# encrypted: .env
# exit 0

# file not encrypted
git-crypt status package.json && echo "exit 0" || echo "exit 1"
# not encrypted: package.json
# exit 0

Answer 1

我可以使用 grep 做到这一点。

# exit 1 if "not encrypted" found
git-crypt status .env | \
    grep "not encrypted" && \
    >&2 echo ".env not encrypted, can't commit" && \
    exit 1

# exit normally
exit 0

也适用于多个文件。

git-crypt status .env package.json | \
    grep "not encrypted" && \
    >&2 echo "files not encrypted, can't commit"
# not encrypted: package.json
# files not encrypted, can't commit
