Indeed. This is my standard response to such muppets:

It offends me to give the little nasty what he wants, so hopefully this
isn't good enough for him:

Put this in a script or alias and call it e.g. lless:

~~~~~~~~~~~~~~~~~~~~~~~~

#!/bin/bash

if [ -z "$1 ] ; then
   echo "No file to display."
   exit 0
fi

L=`tput lines`
W=`tput cols`
F=`wc -l < "$1"`
LL=`wc -L < "$1"`

# If the longest line is longer than the
# terminal width, use ordinary less
if (( $LL > $W )) ; then
      less "$1"
else
   # Otherwise, if the whole thing will fit
   # on the terminal, exit after display
   if (( $L < $F )) ; then
      less "$1"
   else
      less -F -X "$1"
   fi
fi

~~~~~~~~~~~~~~~~~~~~~~~

That will output all lines and exit without clearing the screen if the
number of lines in the first and only argument is less than the number
of lines in the terminal window AND the longest line will fit in the
terminal width. Written without any testing, so use with care!

If you don't care about lack of mousewheel scrolling, just use "less -F
-X file.txt"

Or update to the latest less :-)

Regards, K.
