tail -f grep 一个段落

tag-icon • tag-icon command-line grep tail
tail -f grep 一个段落

我有一个流动的日志文件，文件间以空行分隔。这很困难tail-grep 'PID'当我这样做时，它只显示一行。

这是示例：

我只想看到这个段落包含PID = 00000144

[project worklight_server]

答案1

显然你的记录分隔符（RS）是[project worklight_server]

因此尝试一下：

... | awk -v RS=".project worklight_server."  '/00000144/'

答案2

如果你知道 X 的值（你想要的行数）或者可以用近似值，那么你可以把它放在tail

| grep -A 25 00000144

这将为您提供任何包含 00000144 的行以及接下来的 25 行。

如果您不知道 X 但可以标记输出应该停止的位置，则可以使用sed例如。要从包含 PID 的行转到包含“project worklight_server”的行：

| sed -n '/00000144/,/project\ worklight_server/p'
