Realtime lines per second in a log file, with history
This is similar to standard `pv`, but it retains the rate history instead of only showing the current rate. This is useful for spotting changes. To do this, -f is used to force pv to output, and stderr is redirected to stdout so that `tr` can swap the carriage returns for new lines. (doesn't work correctly is in zsh for some reason. Tail's output isn't redirected to /dev/null like it is in bash. anyone know why? ???????)

Create directory named after current date
Not a discovery but a useful one nontheless. In the above example date format is 'yyyymmdd'. For other possible formats see 'man date'. This command can be also very convenient when aliased to some meaningful name: $ alias mkdd='mkdir $(date +%Y%m%d)'

Remove color codes (special characters) with sed

Print the last modified file

Replace 'csv_file.csv' with your filename.
