I have the following command : sed -i -e '/match1/,+2d' filex, which deletes 2 lines after finding the match "match1" in the file "file x". I want to add several matches to it, like match1, match 2 ....
So it will delete 2 lines after finding any of the matches, how can I achieve this ?

To begin with, if you want to delete a line containing the keyword, you would run sed as shown below. Similarly, you could run the sed command with option -n and negated p , (! p) command. To delete lines containing multiple keywords, for example to delete lines with the keyword green or lines with keyword violet.
To delete a line, we'll use the sed “d” command. Note that you have to declare which line to delete. Otherwise, sed will delete all the lines.
Two ways, depending upon the sed version and platform:
sed -e '/match1/,+2d' -e '/match2/,+2d' < oldfile > newfile or
sed -e '/match1\|match2/,+2d' < oldfile > newfile Not a sed user but it seems to me you could use :
sed -i -e '/(match1|match2)/,+2d' filex Otherwise you could, if that's possible for you to do, do :
sed -i -e '/match1/,+2d' filex && sed -i -e '/match2/,+2d' filex EDIT: Looks like I had the right idea but ziu got it.
