On the off chance that someone finds themselves beating their head against the wall trying to figure out why a coworker's script won't print newlines, look out for this:
<pre><code>#!/bin/bash
function GET_RECORDS()
{
 echo -e &quot;starting\n the process&quot;;
}

echo $(GET_RECORDS);

As in the above, the actual running of the method may itself be wrapped in an echo which supersedes any echos that may be in the method itself. Obviously, I watered this down for brevity. It was not so easy to spot!
You can then inform your comrades that a better way to execute functions would be like so:

POSIX 7 on echo

<a href="http://pubs.opengroup.org/onlinepubs/9699919799/utilities/echo.html" rel="noreferrer">http://pubs.opengroup.org/onlinepubs/9699919799/utilities/echo.html</a>

<code>-e</code> is not defined and backslashes are implementation defined:

<blockquote>
 If the first operand is -n, or if any of the operands contain a &lt;backslash> character, the results are implementation-defined. 
</blockquote>

unless you have an optional XSI extension.

So I recommend that you should use <a href="http://pubs.opengroup.org/onlinepubs/9699919799/utilities/printf.html" rel="noreferrer"><code>printf</code></a> instead, which is well specified:

<blockquote>
 format operand shall be used as the format string described in XBD File Format Notation [...]
</blockquote>

the <a href="http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap05.html#tag_05" rel="noreferrer">File Format Notation</a>:

<blockquote>
 \n &lt;newline> Move the printing position to the start of the next line.
</blockquote>

Also keep in mind that Ubuntu 15.10 and most distros implement <code>echo</code> both as:

<ul>
<li>a Bash built-in: <code>help echo</code></li>
<li>a standalone executable: <code>which echo</code></li>
</ul>

which can lead to some confusion.

This could better be done as

<pre><code>x="\n"
echo -ne $x
</code></pre>

-e option will interpret backslahes for the escape sequence 
-n option will remove the trailing newline in the output

PS: the command echo has an effect of always including a trailing newline in the output so -n is required to turn that thing off (and make it less confusing)

blocks|key|219733|text|有时，您可以传递由一个空格分隔的多个字符串，它将被解释为\n。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|219734|例如，当使用shell脚本进行多行通知时：|219735|#!/bin/bash

Additional solution:
In cases, you have to echo a multiline of the long contents (such as code/ configurations)
For example:
<ul>
<li>A Bash script to generate codes/ configurations</li>
</ul>
<code>echo -e</code>,
<code>printf</code> might have some limitation
You can use some special char as a placeholder as a line break (such as <code>~</code>) and replace it after the file was created using <code>tr</code>:
<pre><code>echo ${content} | tr '~' '\n' &gt; $targetFile
</code></pre>
It needs to invoke another program (<code>tr</code>) which should be fine, IMO.

With <a href="https://stedolan.github.io/jq/manual/v1.6" rel="nofollow noreferrer">jq</a>:
<pre><code>$ jq -nr '&quot;Hello,\nWorld&quot;'
Hello,
World
</code></pre>

How do I print a newline? This merely prints <code>\n</code>:
<pre><code>$ echo -e &quot;Hello,\nWorld!&quot;
Hello,\nWorld!
</code></pre>

Echo newline in Bash prints literal \n
