如何使用sed脚本[08/Mar/2011:00:26:35 +0530]从上面的日志中删除日期，这样有很多实例。

Answer 1

您可以使用：

sed -r 's/\[[0-9]{2}\/[A-Z][a-z]{2}\/[0-9]{4}:[0-9]{2}:[0-9]{2}:[0-9]{2} \+[0-9]+\]//g'

See it on Ideone

或者，如果输入中没有其他[..]出现，您可以这样做：

sed  's/\[.*\]//g'

Answer 2

如果你有Ruby（1.9 +）

$ ruby -i.bak -ne 'print $_.gsub(/\[.*?\]/,"")' file

如果你绝对必须使用sed

$ sed -i.bak 's/\[.[^]]*\]//g' file

Answer 3

一般模式是：

sed -e 's/pattern/replacement/' filename

使用：

-e command

    Append the editing commands specified by the command argument 
    to the list of commands.

在你的情况下，这可能是例如：

sed -e 's/\[.*\]//' yourfilename.log

请注意，只要您在一行中没有其他[.*]个字符，]就会正常工作。
