[Tools] Add a script to move checkpoint files

[zhangchiqing]

This PR adds a tool to move checkpoint files. It does both moving and renaming.

See the following example:

root@mainnettest-24-execution:/var/flow# bash move-checkpoint.sh test/checkpoint.001 test/root.checkpoint
Moved: /var/flow/test/checkpoint.001 -> /var/flow/test/root.checkpoint
Moved: /var/flow/test/checkpoint.001.000 -> /var/flow/test/root.checkpoint.000
Moved: /var/flow/test/checkpoint.001.001 -> /var/flow/test/root.checkpoint.001
Moved: /var/flow/test/checkpoint.001.002 -> /var/flow/test/root.checkpoint.002
Moved: /var/flow/test/checkpoint.001.003 -> /var/flow/test/root.checkpoint.003
Moved: /var/flow/test/checkpoint.001.004 -> /var/flow/test/root.checkpoint.004
Moved: /var/flow/test/checkpoint.001.005 -> /var/flow/test/root.checkpoint.005
Moved: /var/flow/test/checkpoint.001.006 -> /var/flow/test/root.checkpoint.006
Moved: /var/flow/test/checkpoint.001.007 -> /var/flow/test/root.checkpoint.007
Moved: /var/flow/test/checkpoint.001.008 -> /var/flow/test/root.checkpoint.008
Moved: /var/flow/test/checkpoint.001.009 -> /var/flow/test/root.checkpoint.009
Moved: /var/flow/test/checkpoint.001.010 -> /var/flow/test/root.checkpoint.010
Moved: /var/flow/test/checkpoint.001.011 -> /var/flow/test/root.checkpoint.011
Moved: /var/flow/test/checkpoint.001.012 -> /var/flow/test/root.checkpoint.012
Moved: /var/flow/test/checkpoint.001.013 -> /var/flow/test/root.checkpoint.013
Moved: /var/flow/test/checkpoint.001.014 -> /var/flow/test/root.checkpoint.014
Moved: /var/flow/test/checkpoint.001.015 -> /var/flow/test/root.checkpoint.015
Moved: /var/flow/test/checkpoint.001.016 -> /var/flow/test/root.checkpoint.016
Files moved successfully.

Oh, good catch

[fxamacker]

Nice!

Just ideas (feel free to ignore):

• maybe add a flag to use mv -i (for extra safety when used interactively)
• maybe use sha256sum in the script to confirm all the files didn't get modified/corrupted

maybe add a flag to use mv -i (for extra safety when used interactively)

Good point. I added a --run flag, to actually run the mv command, without this flag would be a preview of the files to be moved.

maybe use sha256sum in the script to confirm all the files didn't get modified/corrupted

I'd like to keep the script simple for moving files around, the checksum should be done by separate tools.
