Special character ^@ in CSV file
All,
I am having a tough time with Linux and CSV file. My CSV file gets generated from Cognos on Linux machine that contains special characters. At first instance when I do vi <filename> to that file, I can't see anything. I did tail -2 and redirected to another temp file and did vi <filename>, I can see control characters ^@. I can remove those characters manually by using :%s/^@//g in vi editor. But, the process need to be done automatically as its all automated. Its needs to be done from shell script. The same file came with some other special character in Solaris and was easy to remove.
Any help would be appreciated.

anydata::format::csv
AnyData::Format::CSV(3pm) User Contributed Perl Documentation AnyData::Format::CSV(3pm)
NAME
AnyData::Format::CSV - tiedhash & DBI/SQL access to CSV data
SYNOPSIS
use AnyData;
my $table = adTable( 'CSV', $filename,'r',$flags );
while (my $row = each %$table) {
print $row->{name},"
" if $row->{country} =~ /us|mx|ca/;
}
# ... other tied hash operations
OR
use DBI
my $dbh = DBI->connect('dbi:AnyData:');
$dbh->func('table1','CSV', $filename,$flags,'ad_catalog');
my $hits = $dbh->selectall_arrayref( qq{
SELECT name FROM table1 WHERE country = 'us'
});
# ... other DBI/SQL operations
DESCRIPTION
This is a plug-in format parser for the AnyData and DBD::AnyData modules. It will read column names from the first row of the file, or
accept names passed by the user. In addition to column names, the user may set other options as follows:
col_names : a comma separated list of column names
eol : the end of record mark,
by default
quote_char : the character used to quote fields " by default
escape_char : the character used to escape the quote char, " by default
If you are using this with DBD::AnyData, put ad_ in front of the flags, e.g. ad_eol.
Please refer to the documentation for AnyData.pm and DBD::AnyData.pm for further details.
