私たちは次の行を追加したいと思います:
export KAFKA_HEAP_OPTS="-Xmx8g -Xms8g"
そして:
export KAFKA_JVM_PERFORMANCE_OPTS=" -XX:MetaspaceSize=96m -XX:+UseG1GC-XX:MaxGCPauseMillis=20 - XX:InitiatingHeapOccupancyPercent=35 -XX:G1HeapRegionSize=16M-XX:MinMetaspaceFreeRatio=50 - XX:MaxMetaspaceFreeRatio=80"

awk、sed、Perl onelinerなどを使ってファイルを編集する方法についてのアドバイスを得ることはできますか?

答え3
content
これは、JSONドキュメントを解析せずにPerlを使用して行(各行)を追加する簡単な修正です。以下はコード行です(コマンドラインにコピーして貼り付けます)。私はあなたがこれをしたいと思います:
<in perl -nple'$_.="\\nexport KAFKA_HEAP_OPTS=\"-Xmx8g -Xms8g\"\\nexport KAFKA_JVM_PERFORMANCE_OPTS=\" -XX:MetaspaceSize=96m -XX:+UseG1GC -XX:MaxGCPauseMillis=20 -XX:InitiatingHeapOccupancyPercent=35 -XX:G1HeapRegionSize=16M -XX:MinMetaspaceFreeRatio=50 -XX:MaxMetaspaceFreeRatio=80\"\\n\""
if/^\s+"content"/ '
ここで開始in
は入力ファイルです。画面に出力が表示され、簡単に調整できます。このスイッチを使用して、Perlにファイルを変更させることもできます-i
。 (まずそれについて調べてみましょう。)
出力は次のとおりです。
{

}

ご覧のとおり、ここで修正しました。
export KAFKA_HEAP_OPTS="-Xmx8g -Xms8g"\nexport KAFKA_JVM_PERFORMANCE_OPTS=" -XX:MetaspaceSize=96m -XX:+UseG1GC -XX:MaxGCPauseMillis=20 -XX:InitiatingHeapOccupancyPercent=35 -XX:G1HeapRegionSize=16M -XX:MinMetaspaceFreeRatio=50 -XX:MaxMetaspaceFreeRatio=80"\n
-XX
オプションレイアウトを変更しましたが、エンディングが要求したものでは-XX:MaxMetaspaceFreeRatio=80"\n
ありません。- XX:MaxMetaspaceFreeRatio=80\n"
したがって、これが本当に必要な場合は、この設定を変更してください。さらに、shebangの前の改行文字も削除したいものです。しかし、これはあなたに任せます。
