Finding files by age is something that I find that I commonly do, for example:
find /etc -mtime +10 -maxdepth 1
Will find all files in /etc (maxdepth 1 sets it so that it won’t go into subdirectories) that are more than 10 days old
To find files in a date range, ie: more than 1 day old and less than 2:
find /etc/ -mtime 1 -mtime -2 -maxdepth 1
