如何在PowerShell中运行子目录可执行文件并使其识别自身配置文件

Solution #

The key issue here is that when you run an executable from a parent directory, its working directory defaults to your current location (the main folder), so it will look for asdf1.txt/asdf2.txt in main instead of their respective subfolders. To fix this, you need to launch each executable with its own subfolder as the working directory.

Option 1: Run Sequentially (One After the Other) #

Use Push-Location to switch to each executable's folder, run it, then switch back to the main directory:

# Run exe1 from its own folder
Push-Location .\exe1Folder
.\exe1.exe --config asdf1.txt
Pop-Location

# Run exe2 from its own folder
Push-Location .\exe2Folder
.\exe2.exe --config asdf2.txt
Pop-Location

• Push-Location temporarily changes your working directory to the target subfolder, and Pop-Location reverts it back to main afterward.
• This guarantees each executable looks for its config file in the correct subfolder instead of the parent directory.

Option 2: Run in Parallel (At the Same Time) #

If you want both executables to run simultaneously, use Start-Process with the -WorkingDirectory parameter to set the correct context for each:

# Launch exe1 in its working directory (runs in the same console window)
Start-Process -FilePath ".\exe1Folder\exe1.exe" -ArgumentList "--config asdf1.txt" -WorkingDirectory ".\exe1Folder" -NoNewWindow

# Launch exe2 in its working directory
Start-Process -FilePath ".\exe2Folder\exe2.exe" -ArgumentList "--config asdf2.txt" -WorkingDirectory ".\exe2Folder" -NoNewWindow

• Add the -Wait parameter to either line if you want PowerShell to pause until that executable finishes before moving on.
• Omit -NoNewWindow if you prefer each process to run in its own separate console window.

Why This Works #

By setting the working directory to each executable's subfolder, the relative path asdf1.txt in the --config argument resolves to the file inside exe1Folder instead of the main directory. Without this adjustment, the executable would fail to locate the config file because it's searching in your current working directory by default.
