【问题描述】：

我需要在 OSX 上使用命令行从文本文件中删除字符串。

字符串将具有一些永久特征，但具有任意数字。

我想删除 :-

的所有变体

            [370.15 Kkey/s][total 2999999][Prob 0.0%][50% in 7.8h]

这个字符串有不同的值，但我想删除它，只留下标签部分中的相关信息：-

 PAttern1 :
 Code :
 CodeHash :
 Result :

下面的 MOCK 过程需要发生

 for each line{
if string contains [%d%d%d.%d%d Kkey/s][total %d%d%d%d%d%d%d][Prob %d.%d%][%d%d% in %d.%dh]  (where "%d" is decimal value){

delete string and line

}
else if !contains {

 move down 1 line.
}
{

对于下面的文本，只有模式和散列应该保存到文本文档中

            [370.15 Kkey/s][total 2999999][Prob 0.0%][50% in 7.8h]

我使用 sed 来删除单个字符，如下所示：-

 sed -i '' 's/%/\ /g' file.txt 
 sed -i '' 's/\[/\ /g' file.txt
 sed -i '' 's/]/\ /g' file.txt
 sed -i '' 's/Kkey\/s/\ /g' file.txt

虽然这适用于符号，但我无法猜测数字或 sed 出数字，以防它们在重要的字符串中，并用 sed 替换它！

考虑到上述例程，您将如何处理？

非常感谢您提供的任何帮助

【问题讨论】：

标签： macos bash perl sed terminal

【解决方案1】：

Perl 命令行解决方案：

perl -ne 'print if /\S/ &&  !m|\[\d+\.\d+ Kkey/s]\[total \d+]\[Prob \d+\.\d+%]\[\d+% in \d+\.\d+h]|' your_input_file > your_output_file

【讨论】：

这个好像没有效果
这似乎不太可能。当我运行它时，我会得到一个包含你想要的行的输出文件。如果它对您不起作用，那么您的环境中可能有一些您没有告诉我们的不寻常之处。

【解决方案2】：

您可以将grep 与-v 一起使用：

grep -v 'Kkey/s.*total.*Prob' < input > output

或者如果你也想删除空行：

egrep '^[ \t]*(PAttern1|Code|CodeHash|Result) : ' < input > output

【讨论】：

egrep 似乎效果最好。我可以使用它内联，所以它不需要创建一个新文件？如果我这样做输出 ~/Desktop/file.txt 它会留下一个空白文件。
不能内联，但是可以写到一个临时文件，然后替换原来的：egrep '^[ \t]*(PAttern1|Code|CodeHash|Result) : ' < ~/Desktop/file.txt > .output.txt ; mv ~/Desktop/file.txt ~/Desktop/file.txt.backup ; mv .output.txt ~/Desktop/file.txt
iv 刚刚注意到在我使用的实际示例中，标题后有一个新行，因此脚本失败
例如。 PAttern1: examplepattern1examplepattern1examplepattern1examplepattern1examplepattern1examplepattern1examplepattern1examplepattern1examplepattern1examplepattern1examplepattern1examplepattern1examplepattern1examplepattern1examplepattern1examplepattern1examplepattern1examplepattern1examplepattern1
grep 和 egrep 具有 -A 和 -B 开关，因此您可以在之后或之前拉线。
