sed - 用单引号替换所有双引号

Question

我正在尝试用单引号替换字符串中的所有双引号。这是我的表达：

echo "<a href=\"#\" id=\"resendActivationMailLink\">here</a>" | sed "s/\"/'/"

不幸的是，只有第一个双引号被替换：S

<a href='#" id="resendActivationMailLink">here</a>

有任何想法吗？

您需要将g标志传递给sed：

sed "s/\"/'/g"

You could use tr here, concise and less of quoting headache:

tr '"' "'"

This might work for you:

sed -i "y/\"/'/" hello.txt

-i option is used to edit in place on the file hello.txt.
