git-bash.exe：如何运行单个命令？

Question

I am using the portable version of Git for Windows , but when I use git-bash.exe to run a single command, it looks like it does not work. Can you help me find out where is the problem?

I have a PowerShell script to call below command. But looks like it does not work. I am not able to let the new cmd window to pause to see the error log:

cmd /c "d:\git\git-bash.exe dos2unix d:\test\my-script.sh"

But If double click and run bash-exe.sh , then in the git-bash.exe window type

dos2unix d:\test\my-script.sh

then it works.

Answer 1

There are a few different ways to call EXEs from PowerShell. One of the best ways I've found that allows you the most control is the Start-Process cmdlet. Instead of calling a cmd.exe window try this:

Start-Process -FilePath 'd:\git\git-bash.exe' -ArgumentList 'dos2unix d:\test\my-script.sh'

Better yet convert that shell script into native PowerShell! :)

Answer 2

Anyway, I got a walkaround. In the portable git, under \\usr\\bin, there is a exe called dos2unix.exe, so that I can directly call dos2unix.exe from my powershell scripts, not from git-bash.exe then call dos2unix command.

 cmd /c "d:\git\usr\bin\dos2unix.exe d:\test\my-script.sh"

With this walkaround, the problem resolved. But I still don't know why powershell calls dos2unix to parse my file does not work (I mean the file is not converted after call that command).

另一种解决方案是使用base.exe ，例如：

"%ProgramFiles%\Git\bin\bash.exe" start.sh
