Re: Reading in a text file with "multi line lines"

while (<>) { # read line
  while (s/\\$/ /) {
    # while the current line ends with \
    # replace it by blank and append a new line.
    chomp; # thanks to ww
    $_.= <>;
  }

Update: the chomp should do it. Thanks to ww

Close, but the output doesn't join the lines, as OP asked. I think a big part of the problem is rooted in the thought-process behind your first comment, "`current line ends with \`," which, strictly speaking, is not the case. The lines in question actually end with a "\" and a newline. This helps (but does NOT solve; caveats below) if added after your second `while` : `while (s/\n/ /s) { # remove the newlines my $out = $_; print $out; }` [download] Tested, more-or-less using GrandFather's "framework" (below). And just BTW or nitpicking, your (Skeeve's) comment "`append a new line`" would perhaps be clearer or less ambiguous if written as "`append the next line from DATA.` The problem (yep, this is the caveat) is that with multiple sets of data (which I infer from the OP's '`ignoring all the lines which are blank or contain just "space".`') this still doesn't separate the sets, as does jmcnamara's, below, qv (and ++).

current line ends with \

and a newline

This helps (but does NOT solve; caveats below) if added after your second while :

while (s/\n/ /s) {          # remove the newlines
     my $out = $_;
     print $out;
