blocks|key|537099|text|echo命令有多个版本，具有不同的行为。显然，用于脚本的外壳程序使用的版本不能识别-n。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|537100|printf命令的行为更加一致。对于像echo+hello这样简单的事情，echo是可以接受的，但我建议对任何复杂的事情都使用printf。|537101|你使用的是什么系统，你的脚本使用的是什么shell？|537102|entityMap^0|0|4|15|2|0|0|6|J|A|11|4|1R|6|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@$9|M|A|N|B|C]|$9|O|A|P|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|Q|8|@$9|R|A|S|B|C]|$9|T|A|U|B|C]|$9|V|A|W|B|C]|$9|X|A|Y|B|C]]|D|@]|E|$]]|$1|H|3|I|5|6|7|Z|8|@]|D|@]|E|$]]|$1|J|3|-4|5|6|7|10|8|@]|D|@]|E|$]]]|K|$]]

There are multiple versions of the <code>echo</code> command, with different behaviors. Apparently the shell used for your script uses a version that doesn't recognize <code>-n</code>.

The <code>printf</code> command has much more consistent behavior. <code>echo</code> is fine for simple things like <code>echo hello</code>, but I suggest using <code>printf</code> for anything more complicated.

What system are you on, and what shell does your script use?

Try with 

<pre><code>echo -e "Some string...\c"
</code></pre>

It works for me as expected (as I understood from your question). 

Note that I got this information from the <code>man</code> page. The <code>man</code> page also notes the shell may have its own version of <code>echo</code>, and I am not sure if <code>bash</code> has its own version.

blocks|key|320338|text|bash有一个名为“echo”的“内置”命令：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|320339|$+type+echo

<code>bash</code> has a &quot;built-in&quot; command called &quot;echo&quot;:
<pre class="lang-none prettyprint-override"><code>$ type echo
echo is a shell builtin
</code></pre>
Additionally, there is an &quot;echo&quot; command that is a proper executable (that is, the shell forks and execs <code>/bin/echo</code>, as opposed to interpreting <code>echo</code> and executing it):
<pre class="lang-none prettyprint-override"><code>$ ls -l /bin/echo
-rwxr-xr-x 1 root root 22856 Jul 21 2011 /bin/echo
</code></pre>
The behavior of either <code>echo</code>'s with respect to <code>\c</code> and <code>-n</code> varies. Your best bet is to use <code>printf</code>, which is available on four different *NIX flavors that I looked at:
<pre class="lang-none prettyprint-override"><code>$ printf &quot;a line without trailing linefeed&quot;
$ printf &quot;a line with trailing linefeed\n&quot;
</code></pre>

When you go and write your shell script, always use <code>#!/usr/bin/env bash</code> as the first line.
This shell doesn't omit or manipulate escape sequences.
Example:
<pre class="lang-none prettyprint-override"><code>echo &quot;This is first \\n line&quot;
</code></pre>
prints
<pre class="lang-none prettyprint-override"><code>This is first \n line.
</code></pre>

I believe right now your output prints as below
<pre class="lang-sh prettyprint-override"><code>~ echo -e &quot;String1\nString2&quot;
String1
String2

You can use <a href="https://en.wikipedia.org/wiki/Xargs" rel="nofollow noreferrer">xargs</a> to get multiline standard output into same line.

<pre><code>enable -n echo

I have a problem with <code>echo</code> in my script:

<pre><code>echo -n "Some string..."
</code></pre>

prints

<pre class="lang-none prettyprint-override"><code>-n Some string...
</code></pre>

and moves to the next line. In the console it's working correcly without newline:

<pre class="lang-none prettyprint-override"><code>Some string...
</code></pre>

"echo -n" prints "-n"

我的脚本中的echo有一个问题：echo -n "Some string..."打印-n Some string...并移动到下一行。在控制台中，它工作正常，没有换行符：Some string...
