基於文件的特定列的非字典排序，該列是製表符分隔的

file.txt是製表符分隔：

RollNo  Names    Class  Subject  Position
101     Anna     V      Maths    Average
102     Bob      V      Maths    Good
103     Charles  VI     Science  Good
104     Darwin   VI     Science  Improve
105     Eva      VII    English  Improve

我想對這些行進行排序，以便它們按順序顯示Good，，Average：Improve

RollNo  Names    Class  Subject  Position
102     Bob      V      Maths    Good
103     Charles  VI     Science  Good
101     Anna     V      Maths    Average
104     Darwin   VI     Science  Improve
105     Eva      VII    English  Improve

給定file.txt：

RollNo  Names    Class  Subject  Position
101     Anna     V      Maths    Average
102     Bob      V      Maths    Good
103     Charles  VI     Science  Good
104     Darwin   VI     Science  Improve
105     Eva      VII    English  Improve

用數字替換該行的最後一個單詞。使用這些數字進行排序。然後將這些替換為原始單詞：

$ sed -e 's/Good$/1/' -e 's/Average$/2/' -e 's/Improve$/3/' file.txt | sort -k5n | sed -e 's/1$/Good/' -e 's/2$/Average/' -e 's/3$/Improve/'
RollNo  Names    Class  Subject  Position
102     Bob      V      Maths    Good
103     Charles  VI     Science  Good
101     Anna     V      Maths    Average
104     Darwin   VI     Science  Improve
105     Eva      VII    English  Improve

或者，根據該行的最後一個單詞在每行前面加上一個數字，然後按該數字排序。然後刪除第一列：

$ awk 'NR==1 {n=0} $NF=="Good" {n=1} $NF=="Average" {n=2} $NF=="Improve" {n=3} { print n, $0 }' file.txt | sort -n | cut -d' ' -f2-
RollNo  Names    Class  Subject  Position
102     Bob      V      Maths    Good
103     Charles  VI     Science  Good
101     Anna     V      Maths    Average
104     Darwin   VI     Science  Improve
105     Eva      VII    English  Improve
