Number of days back: change/append arbitrary amount of '\|'$[$(date +%Y%j)-x] expressions or specify any n-th day before today for a single day (you have to replace x with 3, 4, 5, whatever ... above I replaced it with 1 and 2 to get listing for yesterday and day before yesterday and 0 for today was not necessary, so left out). Q: How to narrow to *.pdf , *.png, *.jpg, *.txt, *.doc, *.sh or any type of files only? A: Pipe to grep at the end of command. Even shorter: cd && day=3;for a in $(seq $day -1 0);do tree -aicfnF --timefmt %Y%j-%d-%b-%y|grep $[$(date +%Y%j)-$a];done Here it's only needed to change amount of variable day to list period of days back - here is set to three days back (the seq command is adjusted for listing the oldest stuff first).
