<para>
This command is used to display header information from NitrOS-9 memory
modules. <command>Ident</command> displays the module size, CRC bytes (with verification), and for
program and device driver modules, the execution
offset and the permanent storage requirement bytes. <command>ident</command> will
print and interpret the type/language and attribute/revision bytes.
In addition, <command>ident</command> displays the byte immediately following the
module name since most Microware-supplied modules set this byte to
indicate the module edition.
</para>
<para>
<command>Ident</command> will display all modules contained in a disk file. If the
&quot;-m&quot; option appears, <replaceable>path</replaceable> is assumed to be a module in memory.
</para>
<para>
If the &quot;-v&quot; option is specified, the module CRC is not verified.
</para>
<para>
The &quot;-x&quot; option implies the pathlist begins in the execution
directory.
</para>
<para>
The &quot;-s&quot; option causes <command>ident</command> to display the. following module
information on a single line:
</para>
<simplelist>
<member>
Edition byte (first byte after module name)
</member>
<member>
Type/Language byte
</member>
<member>
Module CRC

A &quot;.&quot; if the CRC verifies correctly, &quot;?&quot; if incorrect.
(<command>Ident</command> will leave this field blank if the &quot;-v&quot; option appears.)
