</blockquote><h4>SYNOPSIS</h4><blockquote><p>
<pre>void m
    (
    void * adrs, /* address to change */
    int    width /* width of unit to be modified (1, 2, 4, 8) */

</blockquote><h4>DESCRIPTION</h4><blockquote><p>
This command prompts the user for modifications to memory in byte, short
word, or long word specified by <i>width</i>, starting at the specified address.
It prints each address and the current contents of that address, in turn.
If <i>adrs</i> or <i>width</i> is zero or absent, it defaults to the previous value.
The user can respond in one of several ways:
<dl>
<dt>
RETURN
<dd>

Do not change this address, but continue, prompting at the next address.
<p>
<dt>
<i>number</i>
<dd>

Set the content of this address to <i>number</i>.
<p>
<dt>
. (dot)
<dd>

Do not change this address, and quit.
<p>
<dt>
EOF
<dd>
 Do not change this address, and quit. 
</dl>

<p>
All numbers entered and displayed are in hexadecimal.

<p><strong><i>d</i>(&nbsp;)</strong> - display memory</p>

</blockquote><h4>SYNOPSIS</h4><blockquote><p>
<pre>void d
    (
    void * adrs,   /* address to display (if 0, display next block */
    int    nunits, /* number of units to print (if 0, use default) */
    int    width   /* width of displaying unit (1, 2, 4, 8) */
    )</pre>

</blockquote><h4>DESCRIPTION</h4><blockquote><p>
This command displays the contents of memory, starting at <i>adrs</i>.
If <i>adrs</i> is omitted or zero, <b><i><a href="./usrLib.html#d">d</a></i>(&nbsp;)</b> displays the next memory block, starting
from where the last <b><i><a href="./usrLib.html#d">d</a></i>(&nbsp;)</b> command completed.
<p>
Memory is displayed in units specified by <i>width</i>.  If <i>nunits</i> is omitted
or zero, the number of units displayed defaults to last use.  If
<i>nunits</i> is non-zero, that number of units is displayed and that number
then becomes the default.  If <i>width</i> is omitted or zero, it defaults
to the previous value.  If <i>width</i> is an invalid number, it is set to 1.
The valid values for <i>width</i> are 1, 2, 4, and 8.  The number of units <b><i><a href="./usrLib.html#d">d</a></i>(&nbsp;)</b>
displays is rounded up to the nearest number of full lines.

</blockquote><h1><i>cd</i>(&nbsp;)</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote>  
<p><strong><i>cd</i>(&nbsp;)</strong> - change the default directory</p>

</blockquote><h4>SYNOPSIS</h4><blockquote><p>
<pre>STATUS cd
    (
    char * name /* new directory name */
    )</pre>

</blockquote><h4>DESCRIPTION</h4><blockquote><p>
This command sets the default directory to <i>name</i>.  The default directory
is a device name, optionally followed by a directory local to that
device.
<p>
To change to a different directory, specify one of the following:
<ul>
<li>  an entire path name with a device name, possibly followed by a directory
name.  The entire path name will be changed.</li>
<li>  a directory name starting with a <b>~</b> or <b>/</b> or <b>$</b>.  The directory part
of the path, immediately after the device name, will be replaced with the new
directory name.</li>
<li>   a directory name to be appended to the current default directory.
The directory name will be appended to the current default directory. 
</ul>

<p>

<p>
An instance of ".." indicates one level up in the directory tree.
<p>
Note that when accessing a remote file system via RSH or FTP, the
VxWorks network device must already have been created using
<b><i><a href="./netDrv.html#netDevCreate">netDevCreate</a></i>(&nbsp;)</b>.
<p>
</blockquote><h4>WARNING</h4><blockquote><p>
The <b><i><a href="./usrLib.html#cd">cd</a></i>(&nbsp;)</b> command does very little checking that <i>name</i> represents a valid
path.  If the path is invalid, <b><i><a href="./usrLib.html#cd">cd</a></i>(&nbsp;)</b> may return OK, but subsequent
calls that depend on the default path will fail.
<p>
</blockquote><h4>EXAMPLES</h4><blockquote><p>
The following example changes the directory to device <b>/fd0/</b>:
<pre>    -&gt; cd "/fd0/"
</pre>
This example changes the directory to device <b>wrs:</b> with the local
directory <b>~leslie/target</b>:
<pre>    -&gt; cd "wrs:~leslie/target"
</pre>
After the previous command, the following changes the directory to
<b>wrs:~leslie/target/config</b>:
<pre>    -&gt; cd "config"
</pre>
After the previous command, the following changes the directory to
<b>wrs:~leslie/target/demo</b>:
<pre>    -&gt; cd "../demo"
</pre>
After the previous command, the following changes the directory to
<b>wrs:/etc</b>.
<pre>    -&gt; cd "/etc"
</pre>
Note that <b>~</b> can be used only on network devices (RSH or FTP).
