Unix things I did not know..

Some interesting unix commands I recently discovered: xargs and seq. With these you can do this, for example:

Find all of the files named foo, and create a tar file:

find . -name foo | xargs tar cvfz tarfile.tar.gz

Iterate through your cluster nodes:

for i in `seq 0 7` ; do scp foolib c0-$i:/usr/local/lib ; done
