Files with a size of less than 10M
# find / -size -10M       

When file was last read (min)
# find / -amin 10       

When file data last changed

By this commnad linux find only file with exetantion .txt and
copy again with .doc ( -exec not ask to do )
# find / -name “*.txt” -exec cp {} {}.doc ;
   
Linux find only those file with permisssion 002 and execute
it again 777 ( or full permission )
# find / -perm -002 -exec chmod 777 {} ;
   
    -exec     execute directly
    -ok    asking to do

# find / -name “*.doc” -ok rm {} ;

Incase you want to check all the foders site in directory
# du -h –max-depth=1 /home | sort -h
