On a couple of different systems I have tried, more(1) always exits with status 0. I would have expected more(1) to exit with a not-zero status when invoked with a non-existent file as its standin. Both cat(1) and tail(1) exit with status 1 when trying to open a non-existent file. Why not more(1)? Is this due to an oversight or due to a conscious decision? Does anyone know? -- Rouben Rostamian Telephone: (301) 455-2458 Department of Mathematics and Statistics e-mail: University of Maryland Baltimore County bitnet: rostamian@umbc Baltimore, MD 21228, U.S.A. internet: rostamian@umbc3.umbc.edu

If more(1) or less(1) were to produce a different exit status for each different type of exit action, you could build intelligent wrappers around your pager. 0 - normal exit (falling off the bottom) 1 - quit (q) 2 - next file (:n) 3 - previous file (:p) (and various error exits) And then something like "zmore" would be able to deal with multiple files properly. And you might rewrite "rn" to allow using an external pager, rather than its baroque internal version. -- Felix Lee flee@cs.psu.edu
