I had been trying to clear cache in a remote server and I got these commands.
First login as root user and execute:
[root@server ~]# sync
[root@server ~]# echo 3 > /proc/sys/vm/drop_caches
bash: /proc/sys/vm/drop_caches: Permission denied
But I am getting permission denied error.
how to delete the cache? because of this I am not able to install any application.
