I want to sort it according to the first field and then the second. The problem is that I want lexicographical sort for the first field and numerical for the second.
我想根据第一个字段然后第二个字段对其进行排序。问题是我想要第一个字段的字典排序和第二个字段的数字排序。
I have tried the following:
我尝试了以下方法：
cat tmp.txt | sort -k1,2
sorts both fields lexicographically
按字典顺序对两个字段进行排序
cat tmp.txt | sort -k1 | sort -n -k2
the second sort messes the first.
第二种混淆了第一种。
cat tmp.txt | sort -s -k1.2n
supposedly stable sort that does the second field numerically. Does not work, and sorts second field lexicographically...
所谓的稳定排序，在数字上执行第二个字段。不起作用，并按字典顺序对第二个字段进行排序...
Ideas??
想法？？
