Invoking the YAZ client

It can be started by typing

yaz-client [-m fname] [-a fname] [-c fname] [-v level] [-p target] [-u auth] [-k size] [zurl]

in a UNIX shell / WIN32 console. The zurl, specifies a Z39.50 host and, if specified, the client first tries to establish connection with the Z39.50 target on the host. Options are prefixed by - followed by a particular letter.

The following options are supported:

-m fname

All retrieved transfer records are appended to file fname. All records as returned by a target(s) in Search Responses and Present Responses are appended verbatim to the file.

-a fname

Pretty-print log of APDUs sent and received is appended to the file fname. If fname is - (minus) the APDU log is written to stderr.

-c fname

Sets the filename for CCL fields to fname. If this option is not given the YAZ client reads CCL fields from file default.bib.

-v level

Sets the LOG level to level. Level is a sequence of tokens separated by comma. Each token is a integer or a named LOG item - one of fatal, debug, warn, log, malloc, all, none.

-p target

Specifies proxy address. When set YAZ client will connect to a proxy on the address and port given. The actual target will be specified as part of the InitRequest to inform the proxy about actual target.

-u auth

Specifies authentication. Usually the form user/password is used. This option does the same thing as the auth command.

-k size

Specifies the maximum messages size in kilobytes. The default maximum message size for the YAZ client is 1024 (1 MB).

In order to connect to Index Data's test Z39.50 server on bagel.indexdata.dk, port 210 and with the database name marc, one would have to type

    yaz-client bagel.indexdata.dk:210/marc

In order to enable APDU log and connect to localhost, port 210 (default) and database Default (default) you'd write:

    yaz-client -a - localhost

The following command connects to a local server via UNIX socket /tmp/yaz and sets maximum message size to 5 MB.

    yaz-client -k 5120 unix:/tmp/yaz
