File end marker problem

[DaveKelly]

I have a single file that is a concatination of a lot of other files. Each single file contains a file end marker (\x1a) and therefore the concat file contains multiple file end markers. Please tell me there is a simple way to loop through the concat file a remove all the file end markers. I tried this ....

#!/usr/bin/perl -w

binmode FILE;
open (FILE, "<concatfile");
open (OUT, ">x.txt");

while(<FILE>){
s/\x1a//;
print OUT;
}

But it stops after the first file end marker. Any ideas?

If this is on a DOSish system (which doesn't seem likely given the shebang line your using?) then you would need to move the binmode statement to after the open to which it applies for it to have any effect.

If your on a *nix system, then you shouldn't need the binmode (although I did see something about this changing under some circumstances with 5.8? -- Warning:Vague recollection), but if that is the case, then you probably wouldn't be seeing the problem.

Super - thats got it licked. Thanks a lot. Dave

Try this:

perl -ne 'print unless /\x1a/;' concatfile >x.txt

Update: This only works if the \x1a is on a line by itself. If not, try this:

perl -npe 's/\x1a//;' concatfile >x.txt

This is however virtually the same thing as yours. It works for me on a file with random \x1a scattered throughout it (as does your code if I drop the binmode. If you're on Unix, you don't need it, and you would need to put it after the open of concatfile for it to work as well).

He did not say the marker is on a separate line.

What I have done in the past is to store things into a variable before printing the output. If the file isn't drastically huge, this won't be a problem:

# Just a snippet -- assume variables decared, etc.

while(<FILE>) {
  $out =~ s/\x1a//;
}

print $out;
