The utility I have found, named progress, will show the amount of data transferred when using commands such as cp or mv.
Download this utility by running this command.
git clone https://github.com/Xfennec/progress.git
Then build the utility.
14:39:50 0 ~ jason$ cd progress/ 14:39:53 0 ~/progress jason$ make cc -g -Wall -D_FILE_OFFSET_BITS=64 -c progress.c cc -g -Wall -D_FILE_OFFSET_BITS=64 -c sizes.c cc -g -Wall -D_FILE_OFFSET_BITS=64 -c hlist.c cc -Wall progress.o sizes.o hlist.o -o progress -lm -lncurses -ltinfo
And run this utility to get the progress of an ongoing copy or move operation.
14:45:20 0 ~/progress jason$ ./progress [ 6149] cp /home/jason/Videos/starwars.mkv 11.5% (409.2 MiB / 3.5 GiB)
This is how easy it is to get information about a large copy operation when you are using the shell to move large files.
Copy the executable to /usr/local/bin and it will be accessible at the shell whenever you need it.
