[--host-intranet] |
| 157 |
|

=item B<--host=http://default.tld> |
| 169 |
|
| 170 |
Server host used when URL doesn't have one, ie doesn't begin with 'http:'. |
| 171 |
For example, if --host=http://www.mylib.com, then when 856$u contains |
| 172 |
'img/image.jpg', the url checked is: http://www.mylib.com/image.jpg'. |
| 173 |
|
| 174 |
=item B<--tags> |
| 175 |
|
| 176 |
Tags containing URLs in $u subfields. If not provided, 856 tag is checked. Multiple tags can be specified, for example: |
| 177 |
|
| 178 |
check-url-quick.pl --tags 310 410 856 |
| 179 |
|

| 191 |
|
| 192 |
