Question

I want to display a string in Bash like this:

I m a student

当然,你可以这样做:

echo "I m a student"

但是,我如何在使用插图上的单一引语时做到这一点?

Answer 1

echo  I m a student

不可行。但以下工作:

echo $ I m a student

ash印的手页:

A single quote may not occur between single quotes, even when preceded by a backslash.
....
Words of the form $ string are treated specially. The word expands to string, with backslash-escaped characters replaced as specified by the ANSI C standard.

Answer 2

格伦·杰克曼提到的“简单”解决办法实际上应列为最高一级的答案。在某些局势中,它运作良好,实际上是美丽的。

 I " " m a student

This ends the single quoted string after I then immediately starts a double quoted string containing a single quote and then starts another single quoted string. Bash then concatenates all contiguous strings into one.

美丽!

Answer 3

以下例子有其作用,因为从技术上讲,从两个单一引用的论据之间就出现了“>。



echo  I   m a student

Answer 4

另一种工作方式是使用<条码>f, 取而代之<条码>。

printf  Ix27m a student!
