#!/bin/bash DIR="$1" if [ "$DIR" == "" ]; then echo "Usage: analyse.sh {directory}" exit fi exiftool -r -T -focallengthin35mmformat -aperture -lens -ext NEF -ext ARW $DIR > analysis.txt awk '{print $1, $2}' analysis.txt | sort | uniq -c | \ awk 'BEGIN { OFS = ", " } ; {print $2 $3, $1}' | \ sort -n > analysis.csv echo -e "\"Focal length\",count\n$(cat analysis.csv)" > analysis.csv echo "Created analysis.csv" |
There's a couple of key things going on here.… continue reading.
