[NTLUG:Discuss] sed question

[jm]

thanks.  i realized after i sent the email and played around a bit
that i didn't need the g.  also, i had verified earlier the " is the
last character; it's a csv file automatically created, so the chance
of it being malformed is small.

as a last option, i tried the script once i got home with a more
recent version of mandriva and a (presumably) different version of sed
(though it also shows 4.1.4) - and it does as expected, so i'm
assuming the other version is corrupt.  i'm mailing myself the working
copy to see if it works at work.

thanks for the reply and the suggestions.
