从bash完成文件中复制以下内容是一种天真的做法

 if [-d .git];然后
 echo .git; 
 else 
 git rev-parse --git-dir 2>的/ dev / null的; 
 fi; 
 

您可以将它封装在函数中，或者在脚本中使用它。

压缩成适用于bash或zsh的单行条件

  [-d .git] || git rev-parse --git-dir> / dev / null 2>& 1 
 

I am writing a series of scripts for Git management in zsh.

How do I check if the current directory is a Git repository? (When I'm not in a Git repo, I don't want to execute a bunch of commands and get a bunch of fatal: Not a git repository responses).

Copied from the bash completion file the following is a naive way to do it

if [ -d .git ]; then
  echo .git;
else
  git rev-parse --git-dir 2> /dev/null;
fi;

You could either wrap that in a function or use it in a script.

Condensed into a one line condition suitable for bash or zsh

[ -d .git ] || git rev-parse --git-dir > /dev/null 2>&1
