hi,

I've got this command line that flushes the disk cache on Linux 2.6.16 and later that's very useful to clean big video files from RAM:

sudo sync; sudo echo 1 > /proc/sys/vm/drop_caches

Any of you has an idea how to give a [sudo cmd( message to the [shell] object and on-interactively give the sudo password?

One way is to exclude these commands from needing the password via http://lists.debian.org/debian-user/2004/02/msg00656.html

Another way is pipelining stdin: echo "YOURPASSWORD"|sudo sync; ...

or for some real shell programming and using a textfile for stdin: http://www.tldp.org/LDP/abs/html/io-redirection.html

Thanks big brother, i've added it to Pdpedia tips and tricks

Thanks, I have elaborated the part a bit, and added pros and cons for the three methods.
