I think acording to posix 's/a/b/;s/b/c/' and 's/a/b/ s/b/c/' are
supposed to be the same

But now im confused acording to posix is 's/a/b/ g' one command or two ?


Posix says

The script shall consist of editing commands of the following form:

[address[,address]]function

The command can be preceded by <blank>s and/or semicolons. The function
can be preceded by <blank>s. These optional characters shall have no
effect.
