But making it simple and elegant is likely to be tricky.
now that i think of it... mk creates DAG of dependences and then reduces it by calling commands, going in parallel where applicable. erik's example with grep x *.[ch] boils down to two cases: - for single use, do it simple & slow way -- just run single grep process for all files - but when you expect to traverse those files often, prepare a mkfile (preferably in a semi-automatic way) which will perform search in parallel. caveat: output of one grep instance could end up in the midst of a /line/ of output of another grep instance. -- dexen deVries [[[↓][→]]] I'm sorry that this was such a long letter, but I didn't have time to write you a short one. -- Blaise Pascal
