#!/bin/bash
if [ $# == "0" ]; then
  echo "You can supply a version number to this command...";
  export rev="HEAD";
else
  export rev=$1;
fi
echo "From the current version of your files and to revision $rev"
echo "the following files will be changes:"
echo
"----------------------------------------------------------------------------------"
echo -n "FILENAME OLDVER NEWVER" |gawk '{ printf "%-65s %6s  %6s\n", $1, $2, $3 
}'
rm -f ~/.tmpfile
( cvs di -r $rev --brief > ~/.tmpfile) >& /dev/null
cat ~/.tmpfile | grep -v "RCS file:" | grep -v ^Files | grep -v ^diff | grep -v

grep -v \? | sed -e 's/retrieving revision //g' | xargs | sed -e 's/Index:

gawk '{ printf "%-65s %6s  %6s\n", $1, $2, $3 }' > ~/.cvs2what
cat ~/.cvs2what
echo

echo "This is saved in ~/.cvs2what"
