    Has anybody implemented file locking via shell scripts?

    I need an effective way to allow multiple hosts to collect some data
    locally and then dump it into a structured repository shared via NFS, which
    means I will nead some form of file locking.

    I would like to avoid race conditions from statements like the following:

    [ ! -f $REPOSITORY/.lockfile ] && touch $REPOSITORY/.lockfile &&
    MergeRepository && rm $REPOSITORY/.lockfile

    Any ideas?
