Code:
[soxxx@bsd test]$ ls lat* | sed 's/\(.*\)/mv & &/; s/-/_/; s/\(.*\) \(.*\) \(.*\)/\1 \3 \2/'
mv latest-pkg latest_pkg
mv latest-pkg-calyx latest_pkg-calyx
mv latest-pkg-esat latest_pkg-esat
mv latest-pkg-plig latest_pkg-plig
[soxxx@bsd test]$ ls lat* | sed 's/\(.*\)/mv & &/; s/-/_/; s/\(.*\) \(.*\) \(.*\)/\1 \3 \2/' | sh
[soxxx@bsd test]$ ls
latest_pkg latest_pkg-calyx latest_pkg-esat latest_pkg-plig

Right, I wasn't thinking about 'mv' command at all!
