Why? sed stands for Stream EDitor, it is an editor, and it
derives from ed, the UNIX editor; so sed *IS* an editor.

However, if you mean you want substitute every occurence
but first _in_ _a_ _line_ GNU sed have an easy way doing this:

s/regexp/replaclement/2g

BE AWARE!

POSIX says nothing on mixing 'g' and '$number' flags so
other implementations of sed could think this flag are
incompatible or do fuzzy things.


If you mean you want substitute every occurence but first
_in_ _a_ _file_ then:

sed '0,/a/! s/a/b/' $my_file

.
