I want to insert something if regex is matched to all matched lines in the /etc/fstab file and print out entire /etc/fstab file with the changes
example
if uncommented line starts with 58. "^58\."
and line doesn't contain FOO
and line doesn't contain BOO
and if the line meets these requirements, insert the word BAR in a certain location
finished line would look like this
one line that comes close is this
This of course is my first attempt which doesn't work but it does kinda show
you what I am looking for
so my question is 2 part
1. how can I change a line like this
to this
2. I don't understand how this is working
I understand that "!s" section is saying don't look at lines with THIS in it
in general this is using a SED command, using a regex to throw out 2 seperate expressions, and include one regex.
close, but no cigar

I am using GnuWin32 sed and am having trouble with the regexp - i.e., they don't behave the same way as in UNIX (POSIX and and all that). I have a stream of data, e.g.:
11111'222?'22'33?'333'44444'55555'
I want to insert a \n after those apostrophes that are *not* preceded by a ?.
