Command	Example	Comment
Print all metadata	ffprobe -v error -show_format -show_streams <FILE>
Print bitrate data without element (bit_rate=) from audio stream	ffprobe -v error -show_entries stream=bit_rate -select_streams a -of default=noprint_wrappers=1:nokey=1 <FILE>	Can return "N/A" for example weba; try format=bit_rate instead of stream=bit_rate.
Print bitrate data without element (bit_rate=) from audio stream, using format=bit_rate	ffprobe -v error -show_entries format=bit_rate -select_streams a -of default=noprint_wrappers=1:nokey=1 <FILE>
Print bitrate data without element (bit_rate=) from audio stream, all files in directory	for i in *.<FILE EXT>; do echo "$i"; ffprobe -v error -show_entries stream=bit_rate -select_streams a -of default=noprint_wrappers=1:nokey=1 "$i"; done;
Print bitrate data without element (bit_rate=) from audio stream, all files in directory if bitrate above 128Kb	for i in *.<FILE EXT>; do br=$(ffprobe -v error -show_entries stream=bit_rate -select_streams a -of default=noprint_wrappers=1:nokey=1 "$i"); if [ "$br" -gt 128000 ]; then echo "$br $i"; fi; done;
