title: How can I revert all open files in perforce?
body: <p>I know how to revert a single opened file. However sometimes I hit some issues where I have to revert all files attached in a single changelist or revert all open pending files (default CL or assigned CL) in a client. Is there any way to do that? I tried <code>p4 revert -c &lt;changelist&gt;</code> where  has multiple pending files. It didn't work for me. It works if I mention ALL the file names. </p>
