GnuWin32 sed 4.1.4 regexp matching

Simerian · #1 (**permalink**) 06-22-2005

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 ?.

Expected output:

11111'
222?'22'
33?'333'
44444'
55555'

I used the substitution:

s/\([^?]\)'/\1'\n/g

this should be OK but it didn't work... it replaced those that *did* have a ? in front - I want the opposite.

Any gurus with a suggestion? (apart from sticking to UNIX)

I can't imagine that that code did what you want in Unix either.

You need to escape your single quotes for them to be recognised as characters in the file and not as quotes around part of the command.

Seems to work fine...

Code:

$ sed --version

$ head file1 sed1
==> file1 <==
11111'222?'22'33?'333'44444'55555'

==> sed1 <==
s/\([^?]\)'/\1'\n/g

$ sed -f sed1 file1
11111'
222?'22'
33?'333'
44444'
55555'
