这是我拥有的文件的示例:

C; S; tous; PMJ100; 1; 40; 1

C; S; tous; PMJ100; 1; 40; 11

C; S; tous; PMJ100; 1; 40; 2

C; S; tous; PMJ100; 1; 60; 1

C; S; tous; PMJ200; 1; 40; 1

(其他一些文件有数千行!)

我想要的是最后一列要进行数字排序,例如1 2 ... 9 10 11 etcetc但它必须在6首列中保存原始的“古典”排序!所以结果应该是:

C; S; tous; PMJ100; 1; 40; 1

C; S; tous; PMJ100; 1; 40; 2

C; S; tous; PMJ100; 1; 40; 11

C; S; tous; PMJ100; 1; 60; 1

C; S; tous; PMJ200; 1; 40; 1

尽我所能,并没有在Google上找到任何有用的东西:(

(nb:空行仅用于在stackoverflow上正确显示)

提前感谢帮助的人!

最佳答案

因此,您可以使用以下脚本:

例如,将“结束”添加到您的数据文件以使用:

#!/bin/bash

# Attention!
if [ -f tosort.tmp ]
then
    rm tosort.tmp
fi


if [ -f tosort_done.tmp ]
then
    rm tosort_done.tmp
fi


if [ -f result.out ]
then
    rm result.out
fi


# And a data file must contain a last "end" line.



nosort_previous_symb=""

while read line_data
do

    tosort_symb=`echo $line_data | rev | cut -d";" -f1-1 | rev`
    nosort_symb=`echo $line_data | rev | cut -d";" -f2- | rev`


    if [[ "$nosort_previous_symb" == "" || "$nosort_previous_symb" == "$nosort_symb"  ]]
    then

        echo $tosort_symb >> tosort.tmp

        #refresh nosort_symb
        nosort_previous_symb="$nosort_symb"


    else


        #old nosort_symb to out
        cat tosort.tmp | sort -nk 1 >  tosort_done.tmp

        while read tosort_symb_done
        do

            echo ""$nosort_previous_symb";"$tosort_symb_done"" >> result.out

        done < tosort_done.tmp


        # new nosort
        echo $tosort_symb > tosort.tmp


        #refresh no sort
        nosort_previous_symb="$nosort_symb"

    fi


done < data


# Attention!
rm -f *.tmp


exit

结果:
C;S;tous;PMJ100;1;40;1
C;S;tous;PMJ100;1;40;11
C;S;tous;PMJ100;1;40;2
C;S;tous;PMJ100;1;60;1
C;S;tous;PMJ200;1;40;1
end
