Replacing multiline batch file with a for loop which reads a text file

Question

I currently have a batch file that schedules chkdsk to run on multiple servers pending the next reboot-

c:\pstools\psexec \\server1 -d -u Domain\administrator cmd /c "echo Y | chkdsk c: /F"  
c:\pstools\psexec \\server2 -d -u Domain\administrator cmd /c "echo Y | chkdsk c: /F"  
c:\pstools\psexec \\server3 -d -u Domain\administrator cmd /c "echo Y | chkdsk c: /F"  
c:\pstools\psexec \\server4 -d -u Domain\administrator cmd /c "echo Y | chkdsk c: /F"  
c:\pstools\psexec \\server5 -d -u Domain\administrator cmd /c "echo Y | chkdsk c: /F"  

I am trying to understand how to construct a FOR loop which will read from a txt file composed of -

server1  
server2  
server3  
server4  

The txt file will be located in the data folder on my local e: drive. Also, is there any way to not have to enter the password for the user ID more than once? Appreciate the guidance! Thx and a Happy New Year to all!

Answer 1

You could use a FOR, but you could also create a file named servers.txt that contains:

server1
server2
server3
server4

and run this command:

c:\pstools\psexec @servers.txt ...your command...

PsExec will execute the command on each of the computers listed in the file. Please see the psexec documentation here, and see the @file parameter.

Answer 2

Here's a for loop method:

@echo off
for /f "delims=" %%a in (servers.txt) do (
   c:\pstools\psexec \\%%a -d -u Domain\administrator cmd /c "echo Y | chkdsk c: /F"  
)
