Git Bash：为什么Windows上的Bash启动了一个新实例以运行外部命令？
如果您使用procmon启动git-bash并监视bash.exe，您会看到，只需运行一个像clear这样的简单命令启动bash.exe的新实例。此实例不会在外部命令的使用寿命中持续存在 - 它是启动的，几乎立即终止。因此，如果您键入GREP Hello您会看到，尽管GREP进程仍在运行附加bash.exe Process终止。
BASH是否有一个原因启动新的bash.exe流程，并且有什么方法可以改变此行为？它导致某些环境中的性能问题是Antivirus软件正在检查启动的每个过程：另一个过程是另一个半秒延迟。
If you start git-bash and monitor bash.exe with procmon, you will see that just running a simple command like clear starts a new instance of bash.exe. This instance doesn't stick around for the lifetime of the external command - it is started and almost immediately terminates. Thus if you type grep hello you will see that although the grep process is still running the additional bash.exe process terminates.
Is there a reason bash launches a new bash.exe process and is there any way to change this behaviour? It causes performance problems in certain environments were antivirus software is checking every process that starts: one more process is another half-second delay.
