I hope I'm reading you right, but try this and see if it does what you want: for i in foo bar baz; do cp ${sourcedir}/${i}.old ${newdir}/${i}.new done You should wind up moving sourcdir/foo.old, sourcedir/bar.old, and sourcedir/baz.old to newdir/foo.new newdir/bar.new newdir/baz.new. You could also use for i in foo.old bar.old baz.old; do cp ${sourcedir}/${i} ${newdir}/${i%.*}.new done if you want to remove the existing suffix and replace it with a new one. All of above assumes we're talking about bash now. Hope this helps. -- David S.
