<strong>Synopsis</strong>

<p><strong>cp [-r | -R [-H | -L | -P] ] [-fhipt]</strong> <em>

<p><strong>cp [-r | -R [-H | -L | -P] ] [-fhipt]</strong> <em>

|
|
||
|
|
<p><strong>Description</strong></p>
|
||
|
|
|
||
|
|
<p>In the first synopsis form, the <strong>cp</strong> utility
|
||
|
|
copies the contents of the <em>source_file</em> to the <em>
|
||
|
|
target_file</em>.</p>
|
||
|
|
|
||
|
|
<p>In the second synopsis form, the <strong>cp</strong> utility
|
||
|
|
copies the contents of each named <em>source_file</em> to a file in
|
||
|
|
the destination <em>target_directory</em>. The names of the files
|
||
|
|
themselves are not changed. The <em>target_directory</em> must
|
||
|
|
exist unless there is only one named <em>source_file</em> which is
|
||
|
|
a directory and the <strong>-R</strong> flag is specified.</p>
|
||
|
|
|
||
|
|
<p>If <strong>cp</strong> detects an attempt to copy a file to
|
||
|
|
itself, the copy will fail.</p>
|
||
|
|
|
||
|
|
<p>If <em>target_file</em> does not exist, the mode of the <em>
|
||
|
|
source_file</em> is used, as modified by the file creation mask,
|
||
|
|
when creating <em>target_file</em>. The S_ISUID and S_ISGID file
|
||
|
|
permission bits are never set when creating a new file.</p>
|
||
|
|
|
||
|
|
<p>If <em>target_file</em> already exists and the <strong>
|
||
|
|
-t</strong> option is not specified, its contents are overwritten
|
||
|
|
as binary data and the CCSID attribute is changed to match the
|
||
|
|
CCSID attribute of <em>source_file</em>. The file permission bits,
|
||
|
|
owner, and group of <em>target_file</em> are unchanged. You can
|
||
|
|
force the data to be copied as text data by using the <strong>
|
||
|
|
-t</strong> option. You can force the file permission bits, owner,
|
||
|
|
and group to be copied using the <strong>-p</strong> option.</p>
|
||
|
|
|
||
|
|
<p>Note that when copying to members in the QSYS.LIB file system,
|
||
|
|
many attributes of <em>source_file</em> cannot be preserved because
|
||
|
|
they are associated with the file object and not the member.</p>
|
||
|
|
|
||
|
|
<p>Symbolic links are always followed unless the <strong>
|
||
|
|
-h</strong> option is specified or the <strong>-R</strong> option
|
||
|
|
is specified with the <strong>-H</strong> or the <strong>
|
||
|
|
-L</strong> options. The <strong>-H</strong>, <strong>-L</strong>
|
||
|
|
and <strong>-P</strong> options are ignored unless the <strong>
|
||
|
|
-R</strong> option is specified. In addition, these options
|
||
|
|
override each other and the command's actions are determined by the
|
||
|
|
last one specified.</p>

<dd>If the <strong>-R</strong> option is specified, symbolic links
|
||
|
|
on the command line are followed. Symbolic links encountered in the
|
||
|
|
tree traversal are not followed and the symbolic link is copied
|
||
|
|
instead of the file pointed to by the symbolic link.</dd>

<dt><strong>-L</strong></dt>
|

links on the command line and symbolic links encountered in the

tree traversal are followed.</dd>

<dt><strong>-P</strong></dt>

link.</dd>

|

<dd>If <em>source_file</em> designates a directory, <strong>
|
||
|
|
cp</strong> copies the directory and the entire subtree connected
|
||
|
|
at that point. This option causes <strong>cp</strong> to create
|
||
|
|
special files rather than copying them as normal files. Created
|
||
|
|
directories have the same mode as the corresponding source
|
||
|
|
directory, unmodified by the file creation mask.</dd>

<dt><strong>-f</strong></dt>
|

operations. A new file is created before the data is copied.</dd>

<dt><strong>-h</strong></dt>

symbolic link.</dd>

<dt><strong>-i</strong></dt>
|

<dd>Write a prompt to standard error before copying a file that
|

|
|
would overwrite an existing file. If the response from the standard
|

input begins with the first character for the YES response in the
|
||
|
|
current locale, the file copy is attempted.</dd>
|

<dt><strong>-p</strong></dt>
|

|
|

|
<dd>Preserve in the copy as many of the modification time, access

time, file permission bits, owner, and group as allowed by
|
||
|
|
permissions.
|
||
|
|
|
||
|
|
<p>If the owner and group cannot be preserved, no error message is
|
||
|
|
displayed and the exit value is not altered.</p>
|

|

<p>The S_ISUID and S_ISGID file permission bits are only copied
|

when both the owner and group of the file are successfully

copied.</p>
