[文本处理] 【已解决】BAT：如何在指定位置插入字符

思想之翼

D:\DATA\1.txt记录格式为：
123=000 001=124=003 005 006=125=007
123=000 001=124=003 005 006=125=007
...
123=000=124=003 006=125=007

如何在所有行的第2 4 6 8...个“=”右侧，插入“=”？

结果为：
123=000 001==124=003 005 006==125=007
123=000 001==124=003 005 006==125=007
...
123=000==124=003 006==125=007

不知行否，记录内容最好不要有特殊字符
会在当前目录生成新文件2.txt
