Re^3: print matching lines by Forsaken (Friar) on Jul 10, 2005 at 19:47 UTC
so are you looking for a match between # input 1 and another one? or between any 2 inputs? and, another important question, are all the inputs numerically ordered like that? Remember rule one...	[reply]

this is some code i have tried `while (<FH>) { local $/ = '# input'; if (m/1ord/) { print $/, $_; } }` [download]	[reply] [d/l]

Since the purpose of setting $/ (see http://perldoc.perl.org/perlvar.html#$/) is to change what <> reads, you need to have it set before the loop. while(<>) will still put the input in $_; don't expect $/ to change. Hint: try a simple loop: `local $/ = "# input"; while (<FH>) { print "got record:\n", $_, ":end of record\n"; }` [download] then try to come up with a regex to match the records you want and print the appropriate thing. You'll need the //m flag. Another perfectly fine approach would be to leave $/ unchanged and save the line(s) you want to print, then print them if and when you get "ord".	[reply] [d/l]

That will never match as there is no line with '`1ord`' in it. CountZero "If you have four groups working on a compiler, you'll get a 4-pass compiler." - Conway's Law	[reply] [d/l]

the # input line is not numerically ordered (just to illustrate). so the only match is for the line ord. if it does match then print the # input three lines above	[reply]
