sed 's/.s/.ss/'


but this also changed the line where it ended with dot and 2 spaces to dot and 3 spaces.

sed 's/.[[:space:]]1,/. /g'


Would replace a dot (matched by . or [.], remember . matches any character) followed by one or more whitespace characters ([[:space:]] being the standard equivalent of s) with . followed by two spaces.



You may want to do that for ! and ? as well:



sed 's/([.!?])[[:space:]]1,/1 /g'


With recent versions of GNU sed, you can shorten it to:



sed -E 's/([.!?])s+/1 /g'


Or with perl:



perl -lne 's/[.!?]Ks+/ /g'


[[:space:]] and s matches any whitespace character (though with perl that's limited to the ASCII ones). That includes CR characters though which occur at the end of the lines in MS-DOS text files but are otherwise generally not used as spacing. So those commands may end up breaking MS-DOS line delimiters if applied on MS-DOS formatted files.



Instead of [[:space:]]/s, you could use [[:blank:]]/h which do not include CR (h is supported by perl, but not GNU sed).

Confectionery

Prepared foods made with a lot of sugar or other cabohydrates "Sweetmeat" redirects here. For the racehorse, see Sweetmeat (horse). Not to be confused with Sweetbread. This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods. Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of
