<h1 class="topictitle1">Home directory</h1>
|
||
|
|
<div><p>The <dfn class="term">home directory</dfn> is used
|
||
|
|
as the current directory when you sign on the system. The name of the home
|
||
|
|
directory is specified in your user profile.</p>
|
||
|
|
<p>When your job is started, the system looks in your user profile for the
|
||
|
|
name of your home directory. If a directory by that name does not exist on
|
||
|
|
the system, the home directory is changed to the <span class="q">"root"</span> (/) directory.</p>
|
||
|
|
<p>Typically, the system administrator who creates the user profile for a
|
||
|
|
user would also create the user's home directory. Creating individual home
|
||
|
|
directories for each user under the <samp class="codeph">/home</samp> directory is preferable.
|
||
|
|
The <samp class="codeph">/home</samp> directory is a subdirectory under the <span class="q">"root"</span> (/)
|
||
|
|
directory. The system default expects the name of the home directory of a
|
||
|
|
user to be the same name as the user profile.</p>
|
||
|
|
<p>For example, the command <samp class="codeph">CRTUSRPRF USRPRF(John) HOMEDIR(*USRPRF)</samp> will
|
||
|
|
assign the home directory for John to <samp class="codeph">/home/JOHN</samp>. If the
|
||
|
|
directory <samp class="codeph">/home/JOHN</samp> does not exist, the "root" (/) directory
|
||
|
|
becomes the home directory for John.</p>
|
||
|
|
<p>You can specify a directory other than the home directory as your current
|
||
|
|
directory at any time after you sign on by using the Change Current Directory
|
||
|
|
(CHGCURDIR) CL command, the chdir( ) API, or the fchdir() API.</p>
|
||
|
|
<p>The home directory chosen during process initiation will remain each thread's
|
||
|
|
home directory by default. This is regardless of whether your active user
|
||
|
|
profile for the thread has changed after initiation. However, there is support
|
||
|
|
provided by the <span class="apiname">Change Job (QWTCHGJB)</span> API that can be used
|
||
|
|
to change the home directory being used for a thread to that thread's current
|
||
|
|
user profile's home directory (or the "root" (/) directory if that home directory
|
||
|
|
does not exist). Secondary threads will always inherit the home directory
|
||
|
|
of the thread that created it. Note that the process' current directory does
|
||
|
|
not change when you use <span class="apiname">QWTCHGJB</span> to change the thread's
|
||
|
|
home directory. The current directory is scoped to the process level, and
|
||
|
|
the home directory is scoped to the thread level. Changing the current working
|
||
|
|
directory in any thread changes it for the whole process. Changing the home
|
||
|
|
directory for a thread does not change its current working directory.</p>
