One-line copy command when source and dest path are the same <p>I want to backup a file in some-other sub-directory different from my current directory like this:</p> <pre><code>cp /aaa/bbb/ccc/ddd/eeee/file.sh /aaa/bbb/ccc/ddd/eeee/file.sh.old </code></pre> <p>As you see both source and dest dir are the same, so common convention would be to change to the common directory, perform the copy im <code>./</code>, then change back to the original directory.</p> <p>Is there a single-line command to accomplish the copy in this situation?</p>
