Concatenate two strings together and print in a shell script
<p>I would like to set a command in a bash script (Ubuntu) where I can concatenate two strings together and print them. For example:</p>

<pre><code>Users/Desktop/File_
</code></pre>

<p>and</p>

<pre><code>20_A
</code></pre>

<p>I would like a command that allows me to concatenate them, such as:</p>

<pre><code>Users/Desktop/File_20_A
</code></pre>

<p>In R to do that I use the command <code>paste0</code>. Does that exist also in bash?</p>
