次のBashスクリプトを使用して、最初の関連行をすでに抽出できます。
grep SCN* LOG.TXT > JUNCTIONS.txt
以下のように、すべての接続ポイントのリストが作成されます。
SCN DD1251 At Glasgow Road - Kilbowie Road
SCN DD1271 At Glasgow Road - Hume Street
SCN DD1301 At Glasgow Road - Argyll Road - Cart Street
SCN DD1351 At Kilbowie Road - Chalmers Street
...
ただし、各リンクヘッダの直後に多くのスペースが発生する前に、ノードの最後のリンクまで行を抽出し、次のリンクまでステップサフィックスから始めて何もキャプチャしないようにします。
一致する各インスタンスが見つかった後に追加の行数を含めるようにBASHスクリプトを変更する方法はありますか？
ベストアンサー1
これはあなたが望むものですか？
sed -n '/^SCN/,/^\s*$/p' LOG.TXT
2つのパターン間の行（およびそれを含む行）を印刷します。
- 行の先頭に「SCN」が表示されます（
^SCN）。 - ゼロ個以上の空白文字を含む空行(
^\s*$)
そして以下を出力します。
