質問：
5列のCSVファイルがあります（最初の列は文字列で、残りの4列は整数です）。新しいCSVファイルの3番目の列「インポート」に基づいてフィルタリングしたいと思います。最大の列は上部に、最小の列は下部にあります。
次のようなものを使用する必要があるようです。awk -F '","' 'BEGIN {OFS=","} { if (Revenues($5) > ?? print }' Valuation.csv > Ranking.csv
データ：
Company,Nbr employees, Revenues , Revenues per employee , Valuation

この試み、
head -1 Valuation.csv > Ranking.csv && tail -n+2 Valuation.csv | sort -t '"' -nrk4 >> Ranking.csv
head ....タイトルをランクファイルにコピーtail .... | sort ...4番目の列は、区切り文字であるヘッダーを除いてソートされます"。-n+22行目からファイルを印刷します-nrk4"数値を区切り文字として使用して、4番目の列を逆順に並べ替えます。
