The other plus in the AWK solution is that I can replace /bar/ with /bar|baz|whatever/. In sed that syntax doesn't seem to work.

@jakub.g , I have GNU sed (v4.4 now). Not sure about the others. What I know is that it uses "basic" regular expression syntax by default this is why your example didn't work. To achieve what you want you can either put a backslash in front of each vertical line or you can ask sed to use "extended" regular expressions. More information here: gnu.org/software/sed/manual/html_node/… . Please note that this is applicable to grep as well. Here's my own working example: echo $'0a\n1b\n2c' | sed '/0a\|1b/d'.
