I hadn't realized the other files were also repeated in both
directories. I also had a couple of typos/bugs in the script I
suggested earlier. This allows you to filter on a pattern with
wildcards, and seems superficially to work:
--------------------------------------
#!/bin/bash
# usage: diff-check dir1 dir2 "pattern"
# pattern must be in double quotes to avoid shell expasion
myday=`date +%y%m%d-%H:%M`
outfile="diff-check-$myday"
for f in `ls $1/$3` ; do
fname=${f##*/}
if [ -f $2/$fname ] ; then
echo checking file $fname
echo $fname in $1, $2 >> $outfile
echo "----------------" >> $outfile
diff $1/$fname $2/$fname >> $outfile
echo "================" >> $outfile
nr=$((co ++))
fi
done
echo $co files compared.
---------------------------------------
