So I have a bunch of files that I want to edit at once using sed but the problem is that I need to edit a line and change the text to a file name stored in variable filename. Every time I tried, it changes the text to the literal "filename" and I don't know how to fix it.

The command I've used is:

sed -i 's/$x/'$filename'/g' *.html

    A good idea would be to show how you did it so we can understand it better and help you. Its hard to theoritically solve it. – Mihir Luthra May 22 '20 at 10:06

From your description and the command used I assume that you try to replace a variable text stored in 

X="text2replace"

with a filename stored in 

FILENAME="filename"

According this, a command like 

sed -i "s/${X}/${FILENAME}/g" *.html

should do the job. It will replace all occurrences of text2replace in all HTML files found with the string filename.

This might work for you (GNU parallel and sed):

parallel --header : sed -i 's#{x}#{filename}#' {file} ::: file *.html ::: x pattern ::: filename name
