Difference between put and copyFromLocal?

In bin/hadoop dfs command I find these two options which seems similar to me.

           [-put <localsrc> <dst>]
           [-copyFromLocal <localsrc> <dst>]

Is there any difference between -put command and -copyFromLocal command?

Similarly what is the difference between -get command and -copyToLocal?

They are equivalent. From the source code:

      if ("-put".equals(cmd) || "-copyFromLocal".equals(cmd)) {
        copyFromLocal(new Path(argv[i++]), argv[i++]);


      if ("-get".equals(cmd) || "-copyToLocal".equals(cmd)) {
        copyToLocal(argv, i);
