Hi all,

i need help for my cmd.

Code: Select all

for /f "tokens=1,* delims= " %%i IN (c:\tmp\version.txt) do (
echo %%i>>c:\tmp\version_output.txt
c:\windows\system32\psexec.exe \\%%i cmd /c ver>>c:\tmp\version_output.txt
)

what i need is, that i can catch the output of psexec in a variable (%%version)

Code: Select all

for /f "tokens=1,* delims= " %%i IN (c:\tmp\version.txt) do (
echo %%i>>c:\tmp\version_output.txt
c:\windows\system32\psexec.exe \\%%i cmd /c ver>>%%version
Echo PC %%i have version: %%version
)

thanks a lot

For the code you've shown, you don't really need an actual variable. Something like this should do the trick (I've included what I think you need and also what you asked for, so take your pick):

Code: Select all

for /f "tokens=1,* delims= " %%i IN (c:\tmp\version.txt) do (
echo %%i>>c:\tmp\version_output.txt
for /f "usebackq tokens=*" %%O in (`c:\windows\system32\psexec.exe \\%%i cmd /c ver 2^>nul`) do (
  echo:NoVariableNeeded -- PC %%i have version: %%O
  set version=%%O
  call echo:PC %%i have version:%%version%%
))

cmd | *sh | ruby | chef

Question:
what means 2^>nul?

NUL

The null device is a special file that discards all data written to it, but reports that the write operation succeeded.

It is often used to hide the output (or error output) of a command

Yes, if you want to echo it (or in a for command tail)

I, for one, am not sure what your post intended to say.
