i have a fresh partition /dev/sda4 of 4 GB for cache and it is mounted on /cache.
now i want to make a automated script which cleans the cache after it reaches 90%... i am complete newbie in scripting and awk.. what i got after studing is this df -h | grep /dev/sda4 | awk '/dev/sda4 { print $6 "\t: " $5}' so that it will tell me /cache is how much full.. now please help me to move further.... or send me the script if you have one. thanks.....
