Hi list,
I would like to create an array in the following format:

456 wer,tre

I want to use a command like the following
push @first_array, ;
where the_number = values in 1st column coming from a variable in a loop.
The values in second column ar
Thanx Craig.
That worked. I have another question.

Thanx Dave. I had executed the exact script sent by you.
But the out put on the screen was
grep -E -i -c "abc|Xyz|PQr" test.txt
So, print $var is printing the command string itself and not the out put of
grep command.
Did I miss anything ?
Thanx..

Sorry All...
The 'die' command should have read:
die "ERROR: Problem executing grep, ($!), stopped" if ( $? == 2 );
grep return codes: 0=Found Match; 1=No Match Found; 2=Error.

You appear to be trying to use the command-line version of grep, rather than
a Perl grep. To get what you appear to be looking for in Perl would require
opening the file:
Script: grep.pl
#!perl -w
use strict ;
my $fn = "test.txt" ;
open(INFILE, $fn) or die "Can'
The back-tics will automatically execute the grep command.
So,
$var=`grep -E -i -c "abc|xyz|pqr" test.txt`;
will execute the grep command just like from the shell command line.
The output from the grep command will be captured in $var.
You can check the value of $? for the return value from
Then how do I execute the command in $var ? I want to check the return code
of that grep command. Please help me. I am new to PERL.
Thanx..

Is that the exact line...?
Try:
$var=`grep -E -i -c "abc|xyz|pqr" test.txt`;
Remember to put your shell commands in back-tics...

Hi listers,
I am using the following command in my perl script. But when I execute the
script I am getting the error
"Unrecognized file test: -E at test.pl line 9."
grep -E -i -c "abc|xyz|pqr" test.txt ;
Can someone please tell me what I am doing wrong here ?
All I wanted to do is to search
Cool
thanks.

In your code, you are using what Oracle calls a database link. When you declare the
tables to query from, the \@STAGE001 is specifying a link to another database. I
don't know if mysql or postgreSQL have database links. In Oracle, you need to have
the link set up before the SQL will work.

In Oracle, I believe that the answer to your question is yes ( I am not
familiar with the others ).
Here is a snippet of a .pm that I run using Oracle as the database, it is
ugly but maybe it is what you are looking for.
my $sth = $self->{'dbc'}->prepare("select c.TAG_NAME
Daft question,
Is it possible to join databases without making two calls. I.e. can the join
be done within SQL, not using 2 $db references?
Not sure which databases yet, but probably mysql, oracle, postgreSQL.

Marty
