问题描述
什么是名称和的功能\\ Bash中ç转义字符？什么是它的数值？我已经看到了 \\ CX 是一个控制字符，但对于普通的 \\ C ？似乎
What is the name and function of the \c escape character in Bash? What is its numeric value? I have seen that \cx is a control character, but what about plain \c? It seems that:
echo -e "Hello World\c"
和
echo -en "Hello World"
是等效的。然而，Python不使用它作为转义字符，它是所有我发现的转义字符名单的丢失。这是一个特定的Bash的行为？
are equivalent. However, Python doesn't use it as an escape character, and it is missing from all of the lists of escape characters I found. Is this a Bash-specific behavior?
推荐答案
这实际上是特定于某些版本的回声（我pretty确保 \\ C 从SysV的来到而 -n 版本是一个BSD-ISM）。
That's actually specific to some versions of echo (I'm pretty sure that \c came from SysV while the -n version was a BSD-ism).
这仅仅意味着不输出其后的换行符。
It simply means don't output the trailing newline.
