As far as I know, a forward slash is not a reserved keyword in PowerShell. But running the following in cmd pops up an about dialog
"C:\Program Files\TortoiseSVN\bin\TortoiseProc.exe" /command:about
The same in PowerShell gives:
'C:\Program Files\TortoiseSVN\bin\TortoiseProc.exe' /command:about
You must provide a value expression on the right-hand side of the '/' operator.
At line:1 char:54
+ 'C:\Program Files\TortoiseSVN\bin\TortoiseProc.exe' /c <<<< ommand:about
What gives?
Put an ampersand character in front of the command
Otherwise, it thinks you’re trying to divide the string literal
"C:\Program Files\TortoiseSVN\bin\TortoiseProc.exe"by something, but it doesn’t know by what.
