从文件中删除带有字符的行(Remove lines with the character from the file)

从文件中删除带有字符的行(Remove lines with the character from the file)

我这样说了

'< Jan 20 Sep> This is the sample out put This is Sample > '< Jan 21 Sep> This is the sample out put This is Known Errors >

所以我需要从文件中删除所有>特殊字符。 只需要删除存在一个特殊字符>的行。 我想在下面说出来

'< Jan 20 Sep> This is the sample out put This is Sample '< Jan 21 Sep> This is the sample out put This is Known Errors

I have out put like this

'< Jan 20 Sep> This is the sample out put This is Sample > '< Jan 21 Sep> This is the sample out put This is Known Errors >

So i need to remove all > special character from the file. Only the line where one special character > is present needs to be removed. I would like to have below out put

'< Jan 20 Sep> This is the sample out put This is Sample '< Jan 21 Sep> This is the sample out put This is Known Errors

最满意答案

你可以使用sed

sed '/^>$/d' myfile

如果输出对你有好处，你可以使用-i标志来覆盖你的文件：

sed -i '/^>$/d' myfile

You can use sed

sed '/^>$/d' myfile

If the output if good for you, you can use the -i flag to override your file:

sed -i '/^>$/d' myfile
