Remove Strings from two patterns/characters with sed

debugcn Published at Dev

I want to remove the string inside two patterns/characters, so if I have a file containing "% Blah blah % i want to remove Blah blah as well as the pattern character in this case it will be % %. so after deleting the string all thats left will be "".
Im doing: sed -E '/"%,%"/d' file but that doesn't seem to delete the string.
Any help would be appreciated !

Assuming that % Blah blah % cannot break across a line boundary, and that Blah blah does not itself contain %, then you can use

sed 's/%[^%]*%//' file

Add the g modifier if you need to replace more than one instance of the pattern per line.
