in reply to Favourite One-liners?

It is impossible for me to have a favorite one-liner. Anything I have to type often enough to become a "favorite" would have already been comitted to a script so I wouldn't have to recreate it every time.

That said, your code perl -e 'print <>' filename is a pathological form of cat filename, type filename, or perl -pe1 filename. You load the entire file into memory before printing it while the operation should normally only load a single line at a time (ignore the buffer, please). You're wasting tons of memory when you do that and for no good reason.

    The reason is just because I always remember it. No other reason than that.

    There are plenty of other versions available if I was really concerned about it though, but thanks anyway.

[erix]: hm zipfile-SQLite sounds useful, have you tried it already, Corion?
[erix]: and good morning (sorry :))
[Corion]: erix: Naah, I just saw the announcement and remembered that discussion. Maybe I'll try building a DBD::SQLite with the zip stuff built-in, just for fun
[Corion]: Oh - and a good morning to you too :)
