    Help with unix commands

    I'm trying to use sed, and it asks me to print all lines where b-days are in November or December. The way the input file is set up,

    sed -n '/^[^:]*:[^:]*:[^:]*:11/p' databook

    gives me the b-days in november, i just don't know how to make it do an "or" to get both. any ideas?

    I dunno how to do this portably, but in GNU sed you can use \| to match "either", like so:

    /^[^:]*:[^:]*:[^:]*:\(11\)\|\(12\)/p

          That's just a regular expression. Not more complicated than most of the biochem stuff.

              You think that's bad? We both spend a lot of time in the same city as well.

                    For what? You don't need to know regex to use *nix.

                      Ah, of course, Doing it this way you don't need GNU extensions, AFAICT:

                      /^[^:]*:[^:]*:[^:]*:1[12]/p

                      Every time I use nonstandard extensions (such as the stuff GNU has added to so many *nix tools) anywhere I hear a little BSD daemon shouting at me about hypocrisy...

                        Out of curiosity, would this also work?

                        /^(.*?{3}1[12]/p

                            Except you spend your weekdays in Hull working (well, uni) and home in Lincolnshire on the weekends, whereas I spend my weekdays in Lincolnshire working and my weekends at home in Hull

                              Well, I'm actually spending more time in Hull this year. Not because I've developed an affinity for the place, but because my family drive me nuts.
