PowerShell - Start-Process and Cmdline Switches

Question

I can run this fine    msbuild    C  WINDOWS Microsoft NET Framework v3 5 MSBuild exe   start-process  msbuild -wait   But when I run this code  below  I get an error    msbuild    C  WINDOWS Microsoft NET Framework v3 5 MSBuild exe  v q  nologo   start-process  msbuild -wait   Is there a way I can pass parameters to MSBuild using start-process  I m open to not using start-process  the only reason I used it was I needed to have the  command  as a variable   When I have C  WINDOWS Microsoft NET Framework v3 5 MSBuild exe  v q  nologo on a line by itself  how does that get handled in Powershell     Should I be using some kind of eval   kind of function instead

Unless the OP is using PowerShell Community Extensions which does provide a Start-Process cmdlet along with a bunch of others   If this the case then Glennular s solution works a treat since it matches the positional parameters of pscx start-process   -path  position 1  -arguments  positon 2

Warning   If you run PowerShell from a cmd exe window created by Powershell  the 2nd instance no longer waits for jobs to complete   cmd gt   PowerShell PS gt  Start-Process cmd exe -Wait    Now from the new cmd window  run PowerShell again and within it start a 2nd cmd window  cmd2    PowerShell  PS gt  Start-Process cmd exe -Wait PS gt       The 2nd instance of PowerShell  no longer honors the -Wait request and ALL background process jobs return  Completed  status even thou they are still running    I discovered this when my C  Explorer program is used to open a cmd exe window and PS is run from that window  it also ignores the -Wait request  It appears that any PowerShell which is a  win32 job  of cmd exe fails to honor the wait request   I ran into this with PowerShell version 3 0 on windows 7 x64

I ve found using cmd works well as an alternative  especially when you need to pipe the output from the called application  espeically when it doesn t have built in logging  unlike msbuild   cmd  C   msbuild  args   gt  gt   outputfile

you are going to want to separate your arguments into separate parameter   msbuild    C  WINDOWS Microsoft NET Framework v3 5 MSBuild exe   arguments     v q  nologo  start-process  msbuild  arguments

Using explicit parameters  it would be    msbuild    C  WINDOWS Microsoft NET Framework v3 5 MSBuild exe  start-Process -FilePath  msbuild -ArgumentList   v q    nologo    EDIT  quotes
