用未加密的错误代码目标文件退出git-crypt

Question

我想编写一个git钩子，这样如果我们的.env文件没有加密，提交就会失败。但是，git status总是在代码0的情况下退出。当文件未提交时，如何使用错误代码退出此命令。

# 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

我可以用grep做这件事。

# 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

也可以处理多个文件。

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
