Re^5: Join lines that match an string

in reply to Re^4: Join lines that match an string
in thread Join lines that match an string

From the discussion I see that I misunderstood your initial posting. But I am as confused as kennethk is.

What I think so far:

you have a file with a lot of lines
you want to match several lines and join them into one
the lines you want to match build a consecutive range (e.g. lines 5-11)
the range of lines you want to match starts with a line containing the string "remotely"
the range of lines you want match ends with a line containing the string "p_agrs"

Based upon that, I guessed this code:

#! /usr/bin/perl
use strict;
use warnings;


# open file and read from that handle...
while ( <DATA> ) {
    chomp;
    print if m/remotely/ ... m/p_agrs/;
    print $/ if m/p_agrs/;
}

__DATA__
not me
foo remotely
bar01
bar02
bar03
p_agrs
i am not here
foo2 remotely
barbar01
p_agrs
i am out...

What really isn't clear in the OP is whether you want to keep the lines you don't join in the output or throw those lines away. This isn't even clear from your detailed description, though in your code you throw them away. I assumed the OP wanted to keep those lines and only change the joined lines.	[reply]

My detailed description could not be clear for that detail. I simply tried to summarize those conditions, which got clear enough to me (as I am not the OP). From my personal experience with similar exercises I tend to drop/ignore those lines. I think my example shows that. But I learned that my guess (to drop those lines, which aren't to be joined) was wrong.	[reply]
