我正在尝试 GREP 使用 Ubuntu 赢得超过 50 场比赛的车手。
这是我正在使用的命令：
cat f1.txt | grep -E " ([5-9][1-9]|[1-9][0-9][0-9])*" | sort -n -k5 | uniq -c | tail -n 5

答案1
使用 awk，这将返回第 5 个字段（获胜）大于 50 或不是数字的所有条目。
awk '$5 > 50' f1.txt
你明白了
Rank Country Driver Races Wins
1 [United_Kingdom] Lewis_Hamilton 264 94
2 [Germany] Sebastian_Vettel 254 53
6 [Germany] Michael_Schumacher 307 91
13 [France] Alain_Prost 199 51
68 [Italy] Alberto_Ascari 36 132
因为在这种情况下，这是行中的最后一个字段，您也可以使用
awk '$NF > 50' f1.txt
如果你真的想使用 grep ，你可以使用类似这样的东西，来自 Greg Fenton 的答案，但你需要更改-E为-P使用 Perl 正则表达式，添加\b以指示数字位于单词边界之后，因此没有数字或字母就在它之前，并将\d三位数部分中的第一个更改为[1-9], 以不存在带前导 0 的三位数
grep -P '\b([5-9][1-9]|60|[1-9]\d\d)$' f1.txt
这是假设只有两位数或三位数的胜利。
\b表示单词边界，表示第一个数字之前不能有数字或字母
()意味着在单词边界之后你需要有括号内定义的内容。
[5-9][1-9]表示应该有两位数，其中第一个数字是 5-9，其他数字是 1-9，这意味着它将捕获数字 51-99，排除 60。
|意味着 or 运算符，并且由于 60 被排除在之前的正则表达式中，[5-9][1-9]我们说 or 60。
|[1-9]\d\d表示或三位数字，其中第一位数字是 1-9 后跟任何两位数字，[1-9]\d\d也可以是[1-9][0-9][0-9]
$表示行尾，在最后一个数字之后应该有行尾，这样您就不会捕获不在最后一个字段中、后面没有行尾的数字。
所以基本上 grep 表示查找单词边界，然后是大于 50 的两位或三位数字，然后是行尾。
这部分[5-9][1-9]|60查找两位数字 51-99，这部分[1-9]\d\d查找三位数字，其中第一位数字是 1-9，如果您想使用多于三位数字，请添加另一个数字或使用|like进行操作
grep -P '\b([5-9][1-9]|60|[1-9]\d\d|[1-9]\d\d\d)$' f1.txt
以上是四位数字。
如果您想使用任意数量的数字，请使用类似的内容
grep -P '\b([5-9][1-9]|60|[1-9]\d\d)\d*$' f1.txt
如果由于某种原因 Perl 正则表达式在你的 grep 中不起作用，你可以尝试扩展正则表达式
grep -E '\b([5-9][1-9]|60|[1-9][0-9][0-9])[0-9]*$' f1.txt
答案2
坚持使用的需要grep，怎么样：
grep -E '([5-9]\d|\d\d\d)$' f1.txt
产生：
$ grep -E '([5-9]\d|\d\d\d)$' f1.txt
1 [United_Kingdom] Lewis_Hamilton 264 94
2 [Germany] Sebastian_Vettel 254 53
6 [Germany] Michael_Schumacher 307 91
13 [France] Alain_Prost 199 51
68 [Italy] Alberto_Ascari 36 132
答案3
对于grep（如果你真的需要它awk）那就是：
grep -E '[[:blank:]]0*(5[1-9]|[6-9][0-9]|[1-9][0-9][0-9])[0-9]*$' infile
