information (<b><a href="intro.html#tag_001_003_003">LEGACY</a></b>)</blockquote><h4><a name = "tag_001_014_1271"> </a>SYNOPSIS</h4><blockquote><pre><code>lpstat <b>[</b>-drst<b>]

[</b><i>ID</i>...<b>]</b></code></pre></blockquote><h4><a name = "tag_001_014_1272"> </a>DESCRIPTION</h4><blockquote>The<i>lpstat</i>utility writes to standard output information about the current statusof the printer system.<p>If noargumentsare given,<i>lpstat</i>writes the status of all requests made to<i><a href="lp.html">lp</a></i>by the user that are still in the output queue.</blockquote><h4><a name = "tag_001_014_1273"> </a>OPTIONS</h4><blockquote>The<i>lpstat</i>utility supports the <b>XBD</b> specification, <a href="../xbd/utilconv.html#usg"><b>Utility Syntax Guidelines</b> </a> ,except the option-arguments are optional and cannot be presented as separatearguments.<p>Some of the options below can be followedby an optional<i>list</i>that can be in one of two forms:a list of items separated from one another by a comma,or a quoted list of itemsseparated from one another by a comma or one or moreblank characters,or combinations of both.See the EXAMPLES section.<p>The omission of a<i>list</i>following such options causes all informationrelevant to the option to be written to standard output; for example:<pre><code>lpstat -u</code></pre><p>writes the status of all output requeststhat are still in the output queue.<dl compact><dt><b>-a[</b><i>list</i><b>]</b><dd>Write the acceptance statusof destinations for output requests.The<i>list</i>argumentis a list of intermixed printer names and class names.<dt><b>-c[</b><i>list</i><b>]</b><dd>Write the class names and their members.The<i>list</i>argument is a list of class names.<dt><b>-d</b><dd>Write the system default destination for output requests.<dt><b>-o[</b><i>list</i><b>]</b><dd>Write the status of output requests.The<i>list</i>argument is a list of intermixed printer names, class namesand<i>request ID</i>s.<dt><b>-p[</b><i>list</i><b>]</b><dd>Write the status of printers.The<i>list</i>argument is a list of printer names.<dt><b>-r</b><dd>Write the status of the printer request scheduler.<dt><b>-s</b><dd>Write a status summary, including the status of the printer scheduler,the system default destination,a list of class names and their membersand a list of printers and their associated devices.<dt><b>-t</b><dd>Write all status information.<dt><b>-u[</b><i>list</i><b>]</b><dd>Write the status of output requests for users.The<i>list</i>argument is a list of login names.<dt><b>-v[</b><i>list</i><b>]</b><dd>Write the names of printers and the pathnames of the devicesassociated with them.The<i>list</i>argument is a list of printer names.</dl></blockquote><h4><a name = "tag_001_014_1274"> </a>OPERANDS</h4><blockquote>The following operand is supported:<dl compact><dt><i>ID</i><dd>A<i>request ID</i>,as returned by<i><a

FILES</h4><blockquote>None.</blockquote><h4><a name = "tag_001_014_1277"> </a>ENVIRONMENT VARIABLES</h4><blockquote>The following environment variables affect the execution of<i>lpstat</i>:<dl compact><dt><i>LANG</i><dd>Provide a default value for the internationalisation variablesthat are unset or null.If<i>LANG</i>is unset or null, the corresponding value from theimplementation-dependent default locale will be used.If any of the internationalisation variables contains an invalid setting, theutility will behave as if none of the variables had been defined.<dt><i>LC_ALL</i><dd>If set to a non-empty string value,override the values of all the other internationalisation variables.<dt><i>LC_CTYPE</i><dd>Determine thelocale for the interpretation of sequences of bytes of text data ascharacters (for example, single- as opposed to multi-byte charactersin arguments).<dt><i>LC_MESSAGES</i><dd>Determine the locale that should be used to affectthe format and contents of diagnosticmessages written to standard error,and informative messages written to standard output.<dt><i>LC_TIME</i><dd>Determine the format of date and time strings outputwhen displaying printer status information with the<b>-a</b>,<b>-o</b>,<b>-p</b>,<b>-t</b>or<b>-u</b>options.<dt><i>NLSPATH</i><dd>Determine the location of message cataloguesfor the processing of<i>LC_MESSAGES .</i><dt><i>TZ</i><dd>Determine the timezone used with date and time strings.</dl></blockquote><h4><a name = "tag_001_014_1278"> </a>ASYNCHRONOUS EVENTS</h4><blockquote>Default.</blockquote><h4><a name = "tag_001_014_1279"> </a>STDOUT</h4><blockquote>The standard output is a text file containing the informationdescribed in the OPTIONS section, in an unspecified format.</blockquote><h4><a name =

compact><dt>0<dd>Successful completion.<dt>>0<dd>An error occurred.</dl></blockquote><h4><a name = "tag_001_014_1284"> </a>CONSEQUENCES OF ERRORS</h4><blockquote>Default.</blockquote><h4><a name = "tag_001_014_1285"> </a>APPLICATION USAGE</h4><blockquote>The<i>lpstat</i>utility cannot reliably determinethe status of print requests in all conceivable circumstances.When the printer is under the control of anotheroperating system or resides on a remote systemacross a network, it need not be possible todetermine the status of the print job after ithas left the control of the local operating system.Even on local printers, spooling hardware in theprinter may make it appear that the print jobhas been completed long before the final page is printed.</blockquote><h4><a name = "tag_001_014_1286"> </a>EXAMPLES</h4><blockquote><ol><p><li>Obtain the status of two printers,the pathnames of two printers, a list of all class namesand the status of the request named<b>HiPri-33</b>:<pre><code>lpstat -plaser1,laser4 -v"laser2 laser3" -c HiPri-33</code></pre><p><li>Obtain user print job status using the obsolescentmixed blank and comma form:<pre><code>lpstat -u"ddg,gmv, maw" </code></pre><p></ol></blockquote><h4><a name = "tag_001_014_1287"> </a>FUTURE DIRECTIONS</h4><blockquote>A version of<i>lpstat</i>that fully supports the <b>XBD</b> specification, <a
