如何从powershell脚本中调用cmd批处理

Question

I have

C:\\folder\\tail.exe

C:\\logs\\logfile.log

C:\\script\\shellscript.ps1

How do I run the C:\\folder\\tail.exe from within the C:\\script\\shellscript.ps1

I need to run "C:\\folder\\tailf.exe C:\\logs\\logfile.log" from within C:\\script\\shellscript.ps1 but without relying a seperate batch file, i need to call it directly.

Normally I do: cd C:\\folder\\ and then tailf.exe C:\\logs\\logfile.log

Inside C:\\script\\shellscript.ps1 I tried

start-process C:\fetchmail\tail.exe -argumentlist "C:\fetchmail\logs\fetchmail.log"

i can see a window flashing but dont know if it works, the window should stay open.

Answer 1

You can do what you normally do:

C:\folder\tail.exe c:\logs\logfile.log

Note that if the paths have spaces in them you have to do:

& "C:\fol der\tail.exe" "c:\log s\logfile.log"

Answer 2

1. To accomplish tail.exe running in a separate window and not having the window closed immediately , try:

   cmd /kc:\\folder\\tail.exe c:\\logs\\test.log

2. To start tail.exe in the powershell window, try:

   C:\\folder\\tail.exe c:\\logs\\logfile.log

3. Assuming tail.exe is Tail for Win32 , this is a powershell equivalent of your command:

   get-content c:\\logs\\logfile.log | select -last 10

4. In the Powershell Community Extensions there is a Get-FileTail cmdlet which is a more efficient native powershell tail equivalent.
