Rename all files in a folder using batch

I would like to create a开发者_运维技巧 batch file to rename all the files with extension ".log" in a folder to append with today's date.

For example :

App.log will be appended to App.log06112010 where date is 06112010.

Please suggest

forfiles /m *.log /c "cmd /c ren @file @file06112010"

#!/usr/bin/ksh
export TODAYSDATE=`date "+%m%d%Y"`

umask 000
for filename in $1
do
  if [ ! -f $1 ]; then
    echo "$filename doesn't exist!"
  else
    if [ -d $1 ]; then
      echo "Skipping directory $filename..."
    else
      mv $filename $filename$TODAYSDATE
    fi
  fi
done

Usage: move.sh "*.log"
