hi,

thanx for ur great work....

how do i delete the whitespaces in the output...
First Occurance: 100
the space between ":" and "100"

i tried to use this awk command to delete the whitespaces and i got the error.

can u guys suggest some solutions?

Code:
awk '{sub(/^[\t]+/, ""); print}'


Code:
#!/usr/bin/perl

#use strict;
use warnings;

  sub search_pattern
      {

          my $file_name = $_[0];

          my $search = $_[1];

          open(LOGFILE, $_[0]) or die("Error: cannot open file '$_[0]'\n");

          while (<LOGFILE>)
                {


if ( $_ =~ /$search/ ) {

#print " First Occurance:$val \n";

my $val = $';

`awk '{sub(/^[\t]+/, ""); print "$val"}'`


print "line number:$.\n";

last;
}
}
}

my $file_n ="test.txt";
my $search_p = "total rejected rows:";
&search_pattern($file_n, $search_p);

Errors:

syntax error at search5.pl line 26, near "print"
Execution of search5.pl aborted due to compilation errors.

If I dont give the awk command,

the output is:

First Occurance: 100

line number:8

thanks,

Mercury.

why are you mixing perl with awk. although you can do call an awk statement from inside Perl, but try not to do that. If you want to use Perl in this case, then do it in Perl. To substitute white space, see here for example.
