Multiple exec commands in find

To run multiple commands on the output of find, they can be specified using the following method :

find . -name "*.txt" -exec echo {} \; -exec grep foo {} \;

Here is a way how to clear the linux system buffers. You will need to run this command as root.

To clear the pagecache, dentries and inodes

echo 3 > /proc/sys/vm/drop_caches

To clear just the pagecache, use the following command

echo 1 > /proc/sys/vm/drop_caches

Similarly, to delete just the dentries and inodes :

echo 2 > /proc/sys/vm/drop_caches

This is a non-destructive operation and will only free things that are completely unused.
