pv

Monitor the progress of data through a pipe.

More information.

• Print the contents of the file and display a progress bar:

pv {file}

• Measure the speed and amount of data flow between pipes (`-s` is optional):

command1 | pv -s {expected_amount_of_data_for_eta} | command2

• Filter a file, see both progress and amount of output data:

pv -cN in {big_text_file} | grep {pattern} | pv -cN out > {filtered_file}

• Attach to an already running process and see its file reading progress:

pv -d {PID}

• Read an erroneous file, skip errors as `dd conv=sync,noerror` would:

pv -EE {path/to/faulty_media} > image.img

• Stop reading after reading specified amount of data, rate limit to 1K/s:

pv -L 1K -S {maximum_file_size_to_be_read}
