How to find a match in file and then suffix that match

Question

I have a file "test.xml"
That looks like the below:

CLASS="BAKERS"

GROUP="ABCYYYYY"

TRACK="DASD"

OWNERS="ALPHA"

GROUP="ABCXXXXX"

GROUP="ABCZZZZZ"

I want to use a single SED line command to find all occurrences of

GROUP="ABC

Then within the "" I want add suffix:

_DONE

to all the matches found.

So the result should look like:

CLASS="BAKERS"

GROUP="ABCYYYYY_DONE"

TRACK="DASD"

OWNERS="ALPHA"

GROUP="ABCXXXXX_DONE"

GROUP="ABCZZZZZ_DONE"

This is the command I am using:

`sed -i.bkp '/^GROUP="ABC/ s/$/_DONE"/' test.xml`

but it is appending after the " and not within the ""

Answer 1

It's almost that. But $ means end of line so you have to substitute the last " using "$ instead:

sed -i.bkp '/^GROUP="ABC/ s/"$/_DONE"/' test.xml

you could also specify that there is some blank after the " with for instance "[ \t]*$
