How do I use ffmpeg to extract the total time of a video slice without actually producing the video slice?

I have a video named 'ev.mp4'. Slice the video into segments:

# COMMAND 1
ffmpeg -i "ev.mp4" -c copy -map 0 -segment_time 15 -g 9 \
    -sc_threshold 0 -force_key_frames "expr:gte(t,n_forced*9)" \
    -reset_timestamps 1 -f segment ev-%04d.mp4

ev-0000.mp4
ev-0001.mp4
ev-0002.mp4

Get each segment time

# COMMAND 2
for f in ev-*.mp4;
do
    echo $f == $(ffprobe -v error -show_entries \
    format=duration -of default=noprint_wrappers=1:nokey=1 $f);
done;

ev-0000.mp4 == 17.251000
ev-0001.mp4 == 17.918000
ev-0002.mp4 == 10.444000

I am only able to extract the duration of each sliced segment after the videos have existed in a sliced format on the hard drive e.g. ev-0000.mp4

My question: is it possible to get the duration of each slice from COMMAND 1 such that instead of producing the sliced files, I will get the duration of each slice?

No, it is not possible. The segment muxer is intended to write its outputs to files. No file, no template, no way to configure the muxer. Read this
