Default values for positional parameters - dummy question I think
Hi,
Sorry for a dummy question I believe. I am just wanting to know how do I assign a default $1 argument if one is not provided.
At the moment, I am doing something like below:
And then I check $arg1 in case/esac. I am just wondering if there is a way for me to simply do ${1:-foo} and check $1 in case/esac.
At the moment, if I simply do ${1:-foo} and run the script, it seem to be trying to run the foo command instead. Script is working fine just curious for whether I can set $1 to a default value without having to assign it to a variable.

3. Have no limit on the number of arguments
4. Can be rearranged... (15 Replies)

I'm new with 'sed' and for sure something still I don't understand yet with it. If you see my output on ">Output..." portion, the new directory still on "source_dir" instead of "dest_dir".

Net::LDAP::FilterMatch(3) User Contributed Perl Documentation Net::LDAP::FilterMatch(3)NAME
Net::LDAP::FilterMatch - LDAP entry matching
SYNOPSIS
use Net::LDAP::Entry;
use Net::LDAP::Filter;
use Net::LDAP::FilterMatch;
my $entry = new Net::LDAP::Entry;
$entry->dn("cn=dummy entry");
$entry->add (
'cn' => 'dummy entry',
'street' => [ '1 some road','nowhere' ] );
my @filters = (qw/(cn=dummy*)
(ou=*)
(&(cn=dummy*)(street=*road))
(&(cn=dummy*)(!(street=nowhere)))/);
for (@filters) {
my $filter = Net::LDAP::Filter->new($_);
print $_,' : ', $filter->match($entry) ? 'match' : 'no match' ,"
";
}
ABSTRACT
This extension of the class Net::LDAP::Filter provides entry matching functionality on the Perl side.
Given an entry it will tell whether the entry matches the filter object.
It can be used on its own or as part of a Net::LDAP::Server based LDAP server.
METHOD
match ( ENTRY [ ,SCHEMA ] )
Return whether ENTRY matches the filter object. If a schema object is provided, the selection of matching algorithms will be derived
from schema.
In case of error undef is returned.
For approximate matching like (cn~=Schmidt) there are several modules that can be used. By default the following modules will be tried in
this order:
String::Approx
Text::Metaphone
Text::Soundex
If none of these modules is found it will fall back on a simple regexp algorithm.
If you want to specifically use one implementation only, simply do
use Net::LDAP::FilterMatch qw(Text::Soundex);
