Deletion of Lp (Unix)

Comment: There are numerous books which establish the notability of the topic - see ''http://books.google.co.uk/books?id=ZkhMKK_qxNQC&pg=PA3 Introduction to Unix and Shell Programming'', for example.  A general prohibition of content about computer commands does not seem sensible; it would be like forbidding content about mathematical operations and symbols.  If the current content of the page is not liked then there are obvious |alternatives to deletion such as merger with spooling and our |editing policy is to prefer these
Stance: keep
