find /home/lijiajia/ -atime -2 #Find files accessed in the last 48 hours in the system Files

find /home/lijiajia/ -empty #Find files or folders that are empty in the system

find /home/lijiajia/ -nouser #Find files belonging to invalid users in the system (don’t understand what it means)

find /home/lijiajia/ -amin 10 #Find files accessed in the system in the last 10 minutes Files

find /home/ftp/pub -user lijiajia​​​ #Find files belonging to the user lijiajia in the system

find /tmp -user TOM -OR -User George#Find/TMP directory belongs to the files of Tom or George. Display files

find /home/lijiajia/ -name 'elm.cc' -ls #Find files named "elm.cc" in the directory and display the information of these files
