linux - 如何在 Linux 中用 awk 比较连续的区分大小写的单词？

Question

awk '{
for(i = 1; i <= NF; i++) { 
    j = i + 1;
    if($i == $j) {
        print FNR " | " $0 " | " $i; 
    }
}
}' myfile

如果 myfile 有这些行:

There is a storm storm outside .

My my car is red .

输出将是:

1 | There is a storm storm outside . | storm

如何让命令忽略大小写敏感度并同时显示？

2 | My my car is red . | my

你可以使用 'toupper' 将字符串转换为大写

if(toupper($i) == toupper($j)) {
