pv: Stop reading after reading specified amount of data, rate limit to 1K/s.
$ pv -L 1K --stop-at --size ${maximum_file_size_to_be_read}
try on your machine
The command "pv -L 1K --stop-at --size ${maximum_file_size_to_be_read}" uses the "pv" utility to control and monitor the data transfer process between input and output.
Here's a breakdown of the command:
- "pv": This is the command for "Pipe Viewer" utility, which allows you to view the progress and statistics of data flowing through a pipeline.
- "-L 1K": This option sets the data transfer rate limit to 1 kilobyte per second. Using this option, you can control the speed of data transfer.
- "--stop-at": This option tells "pv" to stop transferring data when the specified conditions are met.
- "--size ${maximum_file_size_to_be_read}": This parameter determines the maximum size of the file to be read. The value of "maximum_file_size_to_be_read" can be any valid file size, such as "10M" for 10 megabytes or "1G" for 1 gigabyte.
With this command, "pv" will transfer data from an input source to an output destination, but it will stop once the specified file size is reached. The transfer rate will be limited to 1 kilobyte per second.
