Sed Error Unknown option to 's' + Solution

If you are struggling to figure out why your Sed script is failing this could well be the solution.

Every example you see using sed specifies / as a delimiter.

Now what if your pattern actually includes a slash in the body text?

If you are using a variable you might not realise that you are including a slash.

Easy thing to do, just switch the delimiter to something else like #


sed "s/find/$REPLACE/" 


sed "s#find#$REPLACE#"

and hey presto it works!
