Printing next line with sed

Question

I want to print next line of matching word with sed.

I tried this command but it gives error :

sed -n '/<!\[CDATA\[\]\]>/ { N p}/' test.xml

You need a semicolon between "N" and "p": `{N;p}` – Dennis Williamson Sep 29 '10 at 14:43 — Dennis Williamson, Sep 29 '10 at 14:43

what about grep -e -A 1 regex? It will print line below regex.

With sed, looking for pattern "dd", below works fine as you would:

sed -n '/dd/ {n;p}' file

For file content:

dd
aa
ss
aa

It prints:

aa

awk '/pattern/{getline;print}' file

`/bin/gawk` is about 6 times larger than `/bin/sed` on Linux. On other OSes the ratio is similar, even if the `awk` is not from GNU... – Mikhail T. Jun 27 '18 at 14:29
