append file content in another file when pattern matches

[ste2703]

Hi,

I have a file, say abc.txt, whit some text lines.
The I have a second file, say 123.txt where at a certain point one can read "WORD".
I would like to append the whole content of abc.txt (as it appears in abc.txt) in the line after "WORD".

I was thinking something like

sed '/WORD/ a\ abc.txt content' 123.txt. Is it silly?!

Thaks for your help.

Regards

try breaking abc.txt apart into 2 files at 'WORD' then use "cat"
to insert 123.txt--like this

sed '/WORD/ q' <abc.txt >first.txt

where first.txt contains all lines from abc.txt up to and including
the line with 'WORD' on it

now make another file "second.txt" with the remainder of abc.txt

comm -3 abc.txt first.txt >second.txt

then:

cat 123.txt >>first.txt
cat second.txt >>first.txt

should leave first.txt with the required result.
