<h3>Name</h3>
|
|
<p>
|
|
mv - rename or move files
|
|
</p>
|
|
|
|
<h3>Synopsis</h3>
|
|
<p>
|
|
<tt>/bin/mv</tt> <em>oldname</em> <em>newname</em>
|
|
</p>
|
|
|
|
<h3>Description</h3>
|
|
<p>
|
|
<tt>mv</tt> renames the filesystem object specified by
|
|
<em>oldname</em> so that it is subsequently named <em>newname</em>.
|
|
Both files and directories can be renamed or moved into other parts of
|
|
the filesystem tree. However, devices may not be renamed and
|
|
filesystem objects may not be moved across filesystems.
|
|
</p>
|
|
|
|
<p>
|
|
<tt>mv</tt> accepts no options.
|
|
</p>
|
|
|
|
<p>
|
|
Note that <tt>mv</tt> does <em>not</em> support the Unix idiom
|
|
<tt>mv file1 file2 ... destination-dir</tt> to move a number of files
|
|
at once. In particular, <tt>mv foo bar/</tt> will fail, probably with
|
|
"Is a directory".
|
|
</p>
|
|
|
|
<h3>Requirements</h3>
|
|
<p>
|
|
<tt>mv</tt> uses the following system calls:
|
|
<ul>
|
|
<li> <A HREF=../syscall/rename.html>rename</A>
|
|
<li> <A HREF=../syscall/write.html>write</A>
|
|
<li> <A HREF=../syscall/_exit.html>_exit</A>
|
|
</ul>
|
|
</p>
|
|
|
|
<p>
|
|
As the rename system call is generally not part of the basic system
|
|
calls assignment, <tt>mv</tt> will usually still not function after
|
|
the basic system calls assignment is complete.
|
|
This call is typically part of a later assignment, usually the file
|
|
system assignment.
|
|
Once you implement the system call you should be able to rename
|
|
objects within the same directory.
|
|
To move things between directories you will need to implement
|
|
cross-directory support for rename at the file system layer.
|
|
This may or may not be part of your file system assignment;
|
|
consult your course materials for specific information.
