`open` zurl

  Opens a connection to a server. The syntax for zurl is the same as described above for connecting from the command line.

  Syntax:

  [`(tcp|ssl|unix|http)':'`]host [:port][/base]

`quit`

  Quits YAZ client

`f` query

  Sends a Search Request using the query given.

`delete` setname

  Deletes result set with name setname on the server.

`base` base1 base2 ...

  Sets the name(s) of the database(s) to search. One or more databases may be specified separated by blanks. This commands overrides the database given in zurl.

`show` [start[+number]]

  Fetches records by sending a Present Request from the start position given by start a number of records given by number. If start is not given, then the client will fetch from position of the last retrieved record plus 1. If number is not given, then one record will be fetched at a time.

`scan` term

  Scans database index for a term. The syntax resembles the syntax for `find`. If you want to scan for the word `water` you could write

          scan water

  but if you want to scan only in, say the title field, you would write

          scan @attr 1=4 water

`sort` sortspecs

  Sorts a result set. The sort command takes a sequence of sort specifications. A sort specification holds a field (sort criteria) and is followed by flags. If the sort criteria includes `=` it is assumed that the sort SortKey is of type sortAttributes using Bib-1. The integer before `=` is the attribute type and the integer following `=` is the attribute value. If no `=` is in the SortKey it is treated as a sortfield-type of type InternationalString. Flags observed are: `s` for case sensitive, `i` for case insensitive, `<` for sort ascending and `>` for sort descending.

`sort+`

  Same as `sort` but stores the sorted result set in a new result set.

`authentication` openauth

  Sets up a authentication string if a server requires authentication (v2 OpenStyle). The authentication string is first sent to the server when the `open` command is issued and the Z39.50 Initialize Request is sent, so this command must be used before `open` in order to be effective. A common convention for the authopen string is that the username - and password is separated by a slash, e.g. `myusername/mysecret`.

`lslb` n

  Sets the limit for when no records should be returned together with the search result. See the Z39.50 standard for more details.

`ssub` n

  Sets the limit for when all records should be returned with the search result. See the Z39.50 standard for more details.

`mspn` n

  Sets the number of records should be returned if the number of records in the result set is between the values of `lslb` and `ssub`. See the Z39.50 standard for more details.

`status`

  Displays the values of `lslb`, `ssub` and `mspn`.

`setname`

  Switches named result sets on and off. Default is on.

`cancel`

  Sends a Trigger Resource Control Request to the target.

`format` oid

  Sets the preferred transfer syntax for retrieved records. yaz-client supports all the record syntaxes that currently are registered. See Z39.50 Standard for more details. Commonly used records syntaxes include usmarc, sutrs, grs1 and xml.

`elements` e

  Sets the element set name for the records. Many targets support element sets are B (for brief) and F (for full).

`close`

  Sends a Z39.50 Close APDU and closes connection with the peer

`querytype` type

  Sets the query type as used by command `find`. The following is supported: `prefix` for Prefix Query Notation (Type-1 Query); `ccl` for CCL search (Type-2 Query), `cql` for CQL (Type-104 search with CQL OID), `ccl2rpn` for CCL to RPN conversion (Type-1 Query). `cql2rpn` for CQL to RPN conversion (Type-1 Query).

`attributeset` set

  Sets attribute set OID for prefix queries (RPN, Type-1).

`refid` id

  Sets reference ID for Z39.50 Request(s).

`itemorder` type no

  Sends an Item Order Request using the ILL External. type is either 1 or 2 which corresponds to ILL-Profile 1 and 2 respectively. The no is the Result Set position of the record to be ordered.

`update`

  Sends Item Update Request. This command sends a "minimal" PDU Update to the target supplying the last received record from the target. If no record has been received from the target this command is ignored and nothing is sent to the target.

`.` filename

  Executes list of commands from file filename, just like source on most UNIX shells.

`!` args

  Executes command args in subshell using the `system` call.

`push_commande` command

  The push_command takes another command as its argument. That command is then added to the history information (so you can retrieve it later). The command itself is not executed. This command only works if you have GNU readline/history enabled.

`set_apdufile` filename

  Sets that APDU should be logged to file filename. This command does the thing as option `-a`.

`set_marcdump` filename

  Specifies that all retrieved records should be appended ot file filename. This command does the thing as option `-m`.

`schema` schemaid

  Specifies schema for retrieval. Schema may be specified as an OID for Z39.50. For SRW, schema is a simple string URI.

`charset` negotiationcharset [outputcharset]

  Specifies character set (encoding) for Z39.50 negotiation / SRW encoding and/or character set for output (terminal).

  negotiationcharset is the name of the character set to be negotiated by the server. The special name `-` for negotiationcharset specifies no character set to be negotiated.

  If outputcharset is given, it specifies name of the character set of the output (on the terminal on which YAZ client is running). To disable conversion of characters to the output encoding, the special name `-` (dash) can be used. If the special name `auto` is given, YAZ client will convert strings to the encoding of the terminal as returned by `nl_langinfo` call.

  Since character set negotation takes effect in the Z39.50 Initialize Request you should issue this command before command `open` is used.

  MARC records are not covered by Z39.50 character set negotiation. See `marccharset`.

`marccharset` charset

  Specifies character set for retrieved MARC records so that YAZ client can display them in a character suitable for your display. See `charset` command. If `auto` is given, YAZ will assume that MARC21/USMARC is using MARC8/UTF8 and ISO-8859-1 for all other MARC variants.

`set_cclfields` filename

  Specifies that CCL fields should be read from file file filename. This command does the thing as option `-c`.

`set_cqlfields` filename

  Specifies that CQL fields should be read from file file filename. This command does the thing as option `-q`.

`register_oid` name class OID

  This command allows you to register your own object identifier - so that instead of entering a long dot-notation you can use a short name instead. The name is your name for the OID, class is the class, and OID is the raw OID in dot notation. Class is one `appctx`, `absyn`, `attet`, `transyn`, `diagset`, `recsyn`, `resform`, `accform`, `extserv`, `userinfo`, `elemspec`, `varset`, `schema`, `tagset`, `general`. If you're in doubt use the `general` class.
