find dan rm

find ./ -mtime +100 -exec rm -r {} \;

cari dalam ./ file yang berumur lebih dari 100 hari, dan delete.
> +100 : 100 hari dan lebih
> -100 : kurang dari 100 hari
> 100 : exact 100 hari


lain-lain pilihan:
-amin, -atime, -cmin, -ctime, -mmin, and -mtime

c(ctime) > file's status
a > access
m > File's data modified

time > day(24 hours)
min > min
