One liners:
  • Oldest 
    find . -printf "%T@ %Tx %TX %p\n" | sort -n | head | cut -d ' ' -f 2-

  • Newest 
    find . -printf "%T@ %Tx %TX %p\n" | sort -n -r | head | cut -d ' ' -f 2-



Shell scripts:
  • Oldest 
    #!/bin/ksh
touch -t $(($(date "+%Y") + 1))$(date "+%m%d%H%M") compareTo
OLDEST=compareTo
find . -type f | while read f; do
    [[ $f -ot $OLDEST ]] && OLDEST=$f
done
echo oldest file: $OLDEST
rm compareTo


  • Newest 
    #!/bin/ksh
touch -t 197001010000 compareTo
NEWEST=compareTo
find . -type f | while read f; do
    [[ $f -nt $NEWEST ]] && NEWEST=$f
done
echo newest file: $NEWEST
rm compareTo
