I assuming that I am reading all files from /tmp/ directory

for File in /tmp/*
do
   ## Check, if it is a File
   if [ -f $File ] ; then
     ## Yes, it is a file
     ## Get the basename and cut two characters
      TWOBYTES=`basename $File | cut -b1,2`
      if  [ "$TWOBYTES"  = "%!" ] ; then
          echo "File Name Valid"
      else
                  echo "File Name Not Valid"
      fi
   else
      ## This is a directory
      ## I do not know what you want to do here , put your code here.
   fi
done




Hi,
	anyone point me to the best bash script option for checking the
first 2
characters of all the files in a directory?

logic of the script is

for each file in directory
	test if the first 2 chars are "%!"
		print Filename	valid
	if not
		print Filename	not valid


Does magic do something like this ?
