I am getting fonder and fonder of xargs. It basically reads some input and appends it to a pre-supplied string. Then executes the newly created string as a command.

Trivial example:

    ls -1 | xargs -L1 echo processing 

I am finding it quite useful to load and delete a bunch of netapp volume snapshots in a single line:

    ssh netappuser@netapphost volume snapshot show $volname | awk '/selector_pattern/{print $1}' | xargs -L1 ssh netappuser@netapphost volume snapshot delete $volname
