zoomsh - ZOOM shell SYNOPSIS
zoomsh [-e] [-v loglevel] [commands...] DESCRIPTION
zoomsh is a ZOOM client with a simple command line interface. The client demonstrates the ZOOM API and is useful for testing targets. You may pass one or more commands to zoomsh. These commands are invoked first. OPTIONS
-e Makes zoomsh stop processing commands as soon as an error occur. The exit code of zoomsh is 1 if error occurs; 0 otherwise. -v loglevel Sets YAZ log level. EXAMPLES
If you start the yaz-ztest in one console you can use the ZOOM shell as follows: $ zoomsh ZOOM>connect localhost:9999 ZOOM>search computer localhost:9999: 7 hits ZOOM>show 0 1 1 Default USmarc 001 11224466 003 DLC 005 00000000000000.0 008 910710c19910701nju 00010 eng 010 $a 11224466 040 $a DLC $c DLC 050 00 $a 123-xyz 100 10 $a Jack Collins 245 10 $a How to program a computer 260 1 $a Penguin 263 $a 8710 300 $a p. cm.
