Concat Variable (date) and String in shell unix - bash
<p>I'm trying to concat a var (date) and string to have a file with current date name.</p>

<p>My code.</p>

<pre><code>days="$(date +"%Y%m%d_%H%M")"
echo "SKIP" &gt; ${days}_EMERGENCY.txt
</code></pre>

<p>but when I run, I get a file with a ? in file name, like this:</p>

<p>Am I doing something wrong?</p>

<p>EDIT</p>

<p>Looking at symbol, ? stands for \r - could it be because I'm writing on notepad and then upload via ftp the .sh script?</p>

<p>EDIT 2</p>

<p>Tried with vi on local machine - now it's also worse.
