To run the command:

1. Change directory to the folder that contains the input file sort-rand-199999999.txt: cd /path/to/folder
2. Optionally, replace sort-rand-199999999.txt with another input file. Make sure that the file is located in the current directory.
3. Run the command: time docker run -v $PWD:/input -v $PWD:/output clickads/terasort:latest ./prog /input/sort-rand-199999999.txt /output/out.txt

This command runs a Docker container that uses the clickads/terasort image and sorts the specified input file from the /input directory to the /output/out.txt file. The time command is used to measure the execution time of the command.

Replace /path/to/folder with the absolute path of the folder that contains the input file. Replace sort-rand-199999999.txt with the filename of the input file you want to use.

Note that the clickads/terasort image is not provided in this snippet and needs to be downloaded separately.
