# pv
# Monitor the progress of data through a pipe.
# More information: <https://manned.org/pv>.
# Print the contents of the file and display a progress bar:
pv path/to/file
# Measure the speed and amount of data flow between pipes (`--size` is optional):
command1 | pv --size 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 --stop-at --size maximum_file_size_to_be_read
