brace expansion is also useful for renaming/changing hierarchies: mv topo{lo,raph}ical.data mv proj/src/{main,test}/com/org/proj/Test.java

  How can that work?

    Actually, the first one does need the g, should be mv topo{log,graph}ical.data It works because it expands to mv topological.data topographical.data try it with echo instead of mv to see how it expands. Other uses: mv myfile.txt{,.tmp} # add extension mv mymusic.{mp3,mp4} # change extension mv myarchive.{zip,jar}
