循环中BASH中的echo / printf没有换行符

Question

why on executing following script each printf (tried also with echo) is printed on the same line??

function read_dom () {
    local IFS=\>
    read -d \< ENTITY CONTENT
}

cat my_xml_file.xml | \
{   while read_dom; do
        printf "(entity:content %s:%s)" $ENTITY $CONTENT
}

Now, this produces a single line output:

(entity:content member:)(entity:content name:id)(entity:content /name:)

How do I change this to multiline, like:

(entity:content member:)
(entity:content name:id)
(entity:content /name:)

Answer 1

您只需要在printf语句中添加换行符\\n ：

printf "(entity:content %s:%s)\n" $ENTITY $CONTENT

Answer 2

printf不会将换行符附加为标准行为，您需要将其添加到打印字符串中：

printf "(entity:content %s:%s)\n" $ENTITY $CONTENT
