cndump # display all notes (boxed table)
cndump -s # simple output (no box borders)
cndump -d # sort by date (newest first)
cndump -c # sort by category
cndump -r # reverse sort order

- `-c, --category` - Sort by category
- `-r, --reverse` - Reverse sort order
- `-a, --archive` - Show archived entries instead of active
