Hi, I have a litle dos batch script run schedule every night, how do I modify the dos batch script so that I want everything the output on the screen save as a log file? thanks

Append >> log.txt to your echo commands. "Computer security." — Oxymoron

here is my script: can you help me where to put append commnad to save log file? @echo off echo "This batch will shutdown all PCs" psshutdown -r -c -f -t 30 \\computer1 -m "This PC will shut down in 10 sec to complete software upgrade."

Sure, @echo off echo "This batch will shutdown all PCs" psshutdown -r -c -f -t 30 \\computer1 -m "This PC will shut down in 10 sec to complete software upgrade." >> log.txt "Computer security." — Oxymoron
