in reply to Equivalent of Linux Grep Command

That's a reasonable start to an implementation. Any solution I can think of involve scanning the file and maintaining @before and @after buffers as you go.

Perl isn't really intended to provide one liners for every common unix command, and grep itself is a tool not a programming language, any implementation of grep in C is considerably more than one 80 character line of code.

There is a program called prep on CPAN, which is a pure perl implementation of grep. The source to that program may provide inspiration.

[Corion]: erix: Well, they also seem to have changed the server, or some software, or whatever, and seem to be in the process of changing the DB schema from having the "username" as primary key to something else.
[Corion]: Far too many things being done at once, or maybe only now has it become apparent that nobody knows that piece of software anymore
[marto]: good morning all
[Corion]: I consider having an abstract key as userid in your system good, because the "real" company-wide (or even larger) user id will likely not fit your criteria well
[Corion]: A good morning marto!
