( [id://3333]=superdoc: print w/replies, xml ) Need Help??

Hi monks, I have written a perl script for reading an input file and checking if there are certain keywords present in that file and remove those lines from the file.

#!/usr/bin/perl use strict; use warnings; open(my $in, '<', 'out2.txt') or die "Cannot open input.txt: $!"; open(my $out, '>', 'out2_mod.sp') or die "Cannot open output.txt: $!"; while (<$in>) { print $out $_ unless /XXXXX/; } close($in); close($out);
How do I modify the perl script to remove the one line above and below the line I am removing currently,as well as remove the line containing XXXXX.

To rephrase. my input file will have

PPPPP XXXXX is my name YYYYY KKKKK UUUUU BBBBB CCCCCC XXXXX is what I play KKKKK NNNNN
I want to find the lines were XXXXX exists and remove the line above and below that line and also line containing XXXXX. So my ouptut should look like
KKKKK UUUUU BBBBB NNNNN

In reply to how to check for a word in a file and if found remove that line, the above line and the below line from the file. by Ganesh Bharadwaj1

  • 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).
