Suppose I have a file that I am editing in vim with the following contents:

$ cat file.txt Red 4 Blue 3 Green 1 Orange 7 Black 8 Yellow 6 Purple 2 White 5

find . -type f -printf '%T@ %p\n' | sort -n | tail -1 | cut -f2- -d" "

To count all the files by file extension recursively on the command line $ find . -type f | sed -n ’s/..*.//p’ | sort | uniq -c 40 3g2 5 AVI 13 DS_Store 28 JPG 30 MOV 133 MP4 64 THM 1 docx 18 jpg 1 json 4 m3u 89 m4a 2 m4r 156 m4v 41 mkv 112 mov 38 mp3 587 mp4 1 nfo 2 osp 30 png 1 sh 4 srt 6 svg 10 torrent 6 txt 5 webm 10 zip
