Jun 28 21:23 file 7

You can use find using newermt (for modification time): find . -newermt "2017-01-03" -type f -ls | wc -l find . -newermt "2017-01-03" -type f -ls | wc -l find . -newermt "2017-01-03" -type f -ls | wc -l and than count the number of lines.

For example:

herbert@projects:~/tmp/datetest$ touch -t 201701020100 a.txt
herbert@projects:~/tmp/datetest$ touch -t 201701030100 b.txt
herbert@projects:~/tmp/datetest$ touch -t 201701040100 c.txt
herbert@projects:~/tmp/datetest$ find . -newermt "2017-01-03" -type f -ls
 82353    0 -rw-r--r--   1 herbert  herbert         0 Jan  4 01:00 ./c.txt
 82352    0 -rw-r--r--   1 herbert  herbert         0 Jan  3 01:00 ./b.txt
herbert@projects:~/tmp/datetest$ find . -newermt "2017-01-03" -type f -ls | wc -l
