How to use a script output as a value in .gitconfig?
问题
我想用我的YubiKey签署我的git提交，但仅在我的YubiKey存在时。我有一个名为 yubikey-present.sh 的脚本，可以运行它，如果YubiKey存在，则输出 true，否则输出 false。
有没有办法运行这个脚本，并将输出用作 ~/.gitconfig 中 commit.gpgsign 的值？我尝试过：
[commit]
gpgsign = !`/path/to/yubikey-present.sh`
但它告诉我：
fatal: bad boolean config value '!`/path/to/yubikey-present.sh`' for 'commit.gpgsign'
英文:
I want to sign my git commits with my Yubikey, but only if my Yubikey is present. I have a script, yubikey-present.sh that I can run that will output true if the yubikey is present and false otherwise.
Is there a way to run this script and use the output as the value for commit.gpgsign in ~/.gitconfig? I've tried:
[commit]
gpgsign = !`/path/to/yubikey-present.sh`
But it tells me:
fatal: bad boolean config value '!`/path/to/yubikey-present.sh`' for 'commit.gpgsign'

你可以尝试编写一个钩子脚本，在每次提交之前更改你的配置。.git/hooks/pre-commit 是一个在每次提交之前运行的钩子脚本。尝试创建一个包含以下内容的脚本：
#!/bin/sh
git config commit.gpgsign "$(/path/to/yubikey-present.sh)"
英文:
You could try writing a hook script that changes your configuration before each commit. .git/hooks/pre-commit is a hook script that is run before each commit. Try a script that contains this line:
#!/bin/sh
git config commit.gpgsign "$(/path/to/yubikey-present.sh)"
