If I read his question right, he asked about just the simple matchers: //. Perl solves this problem with the optional m in front (m//), so you can do m:/foo: or m+/foo+, but I don't know of a similar toggle for sed (well, I'm a sed newbie, so there might still be one). I don't even think substituting the string with itself (s+/foo+/foo+) would work as I think s/// will succeed every time, even when it doesn't actually substitute anything, so maybe it cannot be used for an "if-then" in sed either? -- Arttu V.
