【bash】行番号を指定しての行の取得

More than 5 years have passed since last update.

自分用のメモ。
行番号を指定しての行の取得方法。sed、awk、bashの3通り。

sed

out.datの2行目取得
#sed -n 行番号P 対象ファイル
sed -n 2P out.dat

awk

out.datの2行目取得
#awk 'NR==行番号' 対象ファイル
awk 'NR==2' out.dat

bash

out.datの2行目取得
#head -n 行番号 対象ファイル | tail -n 1
head -n 2 out.data | tail -n 1
