read man page.  you want:

    rename .dat '' *.dat

in what you typed, these are the args rename saw (assuming only the
files you touched are in tst1:

    rename 1.dat 2.dat 3.dat 4.dat 1.dat 2.dat 3.dat 4.dat

which replaces the first string that matches "1.dat" to "2.dat" for the
files 3.dat 4.dat 1.dat 2.dat 3.dat 4.dat.
