How to insert an arbitrary string after pattern with sed

问题

It must be really easy, but somehow I don't get it… I want to process an HTML-file via a bash script and insert an HTML-String into a certain node:

org.html: <div id="wrapper"></div>

MYTEXT=$(phantomjs capture.js www.somesite.com)
# MYTEXT will look something like this:
# <div id="test" style="top: -1.9%;">Something</div>

sed -i "s/\<div id=\"wrapper\"\>/\<div id=\"wrapper\"\>$MYTEXT/" org.html

I always get this error: bad flag in substitute command: 'd' which is probably because sed interprets the content of $MYTEXT as a pattern as well – which is not what I want…

By the way: Duplicating \<div id=\"wrapper\"\> is probably also not necessary?

回答1:

It seems the / in $MYTEXT's </div> part is interpreted indeed as the final / in the sed command. You can choose another delimiter, which does not appear in $MYTEXT, for instance:

sed -i "s|\<div id=\"wrapper\"\>|\<div id=\"wrapper\"\>$MYTEXT|" org.html
