批处理，还是shell。不要混淆！

把原文件打包上来看看！

#!/bin/bash
rm -f result.txt result1.txt 2>/dev/null
for a in `ls *.txt`
do
	grep -o -E "\-[0-9]{1,12}.[0-9]{1,12}" $a | awk -v fname=$a '{printf "%s %s\n",fname,$1}' 1>>result1.txt
done 
sort -nr -t ' ' -k 2 result1.txt 1>result.txt
rm -f result1.txt

还有一个难点我没有明白你的意思！

#!/bin/bash
rm -f result.txt result1.txt 2>/dev/null
for a in `ls *.txt`
do
	grep -o -E "[[:space:]]{2}-[0-9]{1,12}.[0-9]{1,12}[[:space:]]{2}" $a | awk -v fname=$a '{printf "%s %s\n",fname,$1}' 1>>result1.txt
done 
sort -nr -t ' ' -k 2 result1.txt 1>result.txt
rm -f result1.txt

我对shell了解不多，你应该多学学linux三剑客
排序文本最后一次匹配到的数据

#!/bin/bash
rm -f result.txt result1.txt 2>/dev/null
for a in `ls *.txt`
do
	for b in `grep -o -E "[[:space:]]{2}-[0-9]{1,12}.[0-9]{1,12}[[:space:]]{2}" $a`
	do
		temp=$b
	done
	echo $temp |awk -v fname=$a '{printf "%s %s\n",fname,$1}' 1>>result1.txt
done 
sort -nr -t ' ' -k 2 result1.txt 1>result.txt
rm -f result1.txt

	#grep -o -E "[[:space:]]{2}-[0-9]{1,12}.[0-9]{1,12}[[:space:]]{2}" $a | tac n 1 |awk -v fname=$a '{printf "%s %s\n",fname,$1}' 1>>result1.txt

在第四行前面第三行下面

sed.exe -i '4i abcd' aaaa.txt

你的方法可以
给你个查找空行的方法，剩下的自己想办法咯！

grep -n -E "^$" aaaa.txt
