Answer 1

你的文件“结构”在结构部门中有点缺乏，所以你必须在这个过程中处理一些错误。

假设您拥有名为input的文件中的所有内容，请尝试：

tr '[A-Z]' '[a-z]' < input | \
     egrep -v "^ *(join date|age|posts|location|re):" | \
     sort | \
     uniq -c

第一行缩小所有内容，第二行删除样本中看起来像电子邮件标题的内容，然后对唯一项进行排序和计数。

Answer 2

此命令列出行和重复次数

sort nameFile | uniq -c

Answer 3

如何使用awk -

awk '
/:/||/^$/{next}{a[toupper($0)]++}
END{for(i in a) print i,a[i]}' INPUT_FILE

说明：

首先，我们确定其中包含:或blank的行并忽略它们。存储的所有其他行都转换为大写并存储在数组中。在我们的END statement中，我们打印出数组中的所有内容及其找到的次数。

测试：

awk '
/:/||/^$/{next}{a[toupper($0)]++}
END{for(i in a) print i,a[i]}' file1
