How to escape space in PowerShell?

Question

I run this command in PowerShell

Start-Process -FilePath 'C:\Program Files\Typora\Typora.exe' -ArgumentList 'C:\Users\Administrator\Desktop\Hello world.md'

But Typora says

C:\User\Administrator\world.md does not exist

It looks like PowerShell executes

Start-Process -FilePath 'C:\Program Files\Typora\Typora.exe' 
     -ArgumentList 'C:\Users\Administrator\Desktop\Hello' 'world.md'

I want to escape the space but the single-quoted not working...

PowerShell version: 5.1.19041.610

Answer 1

PowerShell may not quote strings properly when calling external executables. See

• Curl in PowerShell with custom cookie file
• PowerShell or CMD errors on space in file path

So to fix this you need to pass the literal " to the exe file by escaping it properly

Start-Process -FilePath 'C:\Program Files\Typora\Typora.exe' `
    -ArgumentList '"C:\Users\Administrator\Desktop\Hello world.md"'

Answer 2

Try adding ` to excape spaces in powershell:

Start-Process -FilePath 'C:\Program Files\Typora\Typora.exe' -ArgumentList 'C:\Users\Administrator\Desktop\Hello`world.md'
