I have a file 'A' which contains n lines of single word strings like
hye
bye
bin
.
.
n
Now I want to look for these words in some other file 'B' and delete those lines wherever they are found and write the new file as 'C'
Till now I am trying to use this..
#!/usr/local/bin/perl
foreach $file (@ARGV) {
# open a file and assign the filehandle F
open(F, $file) or die("can't open myfile.txt: $!\n");
# read in the whole file into an array of lines
@lines = ();
while(<F>) {
push(@lines, $_);
}
close(F); # close the filehandle
foreach (@lines) {
my $string = "@lines";
open(my $infile,"<", file1) or die $!;
open (my $outfile,">>", file2) or die $!;
while (<$infile>)
{
if ($_ !~/$string/)
{
print $outfile $_;
}
}
close $infile;
close $outfile;
}
}
But its giving me error and also not giving results.
Please help !!!

Are you posting in the right place? Check out Where do I post X? to know for sure.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

are good places to start.
