in reply to Printing file to browser

open(FILE,"file.txt") || die; print while <FILE>; close FILE;
Should do the trick. You have to print it on a line-by-line basis, which is what the while loop will do.

UPDATE: You all beat me to it, but mine took less space!! :)

    Well, yes, but a) you didn't explicitly note the problem of not checking the return value of the call to open and b) you're wrong when you say it has to be done line-by-line -- either construct nysus tried should work (and does, on my system =)

    Philosophy can be made out of anything. Or less -- Jerry A. Fodor

      You're right, it doesn't have to be printed line-by-line. But I would recommend it.

      The reason is that if the file is large, then the user will (usually) see what's been read and printed so far (assuming no caching, buffering, etc) if you do it line-by-line, but will have to wait until the whole file is processed if you do it as an array slurp. And, possibly, the connection might time-out durring the slurp if you're not careful.

      Of course, I could be totally mistaken. :-)
