Or sed -rn 's/^### ?//p'

  Doesn't appear anyone has tried addressing before replacement - ie the simplest sed work-a-like - if you don't mind the leading ### is just: sed -n '/^### /p' I believe? (equivalent to grep). Then eg: sed -nr '/^### /s/^.{4}(.*)/\1/p' (or without the redundant addressing, just:) sed -nr 's/^### (.*)/\1/p'

    You can simplify sed -nr 's/^.{4}(.*)/\1/' to sed -nr 's/^.{4}// And if you use a pattern for the address, you can repeat it in the substitution by using an empty pattern, so sed -nr '/^### /s/^.{4}(.*)/\1/p' is the same as sed -nr '/^### /s/^.{4}//p' is the same as sed -nr '/^### /s///p' at which point I prefer just the substitution: sed -nr 's/^### //p'
