Question

我想从SVN日志中提取行之间的所有文本。如果是sed，awk或grep那就更好了。

示例： svn.log

这个awk oneliner为您提供所需的输出：

awk -vRS='-+\n' '/Ticket #1000/' svn.log

<强>测试

kent$  awk -vRS='-+\n' '/Ticket #1000/' svn.log

您已经看到行分隔符（-----）未输出。如果你真的需要它可以很容易地添加。

Answer 2

我建议使用svn log的xml输出，并从xml文件中提取信息，而不是......可能更简单......

svn log --xml ...

Answer 3

有趣的运动，所以我去了！

% awk ' 
{
    lines = lines "\n" $0
}

/Ticket #1000/ {
    found = 1
}

/^-+$/ {
    if (found) {
        print lines
    }
    lines = $0
    found = 0
}
' svn.log

我认为这是不言自明的，但如果不是，我会更新答案。

即使多个提交包含搜索字符串，这也能正常工作。

将搜索字符串变量留作练习。

使用：

进行测试

% awk --version
awk version 20070501

我更喜欢避免单行。如果你喜欢那种东西，那么你需要在语句之间使用分号。

这可能对您有用：

 sed '/^-\+$/{h;:a;$d;N;/-\+$/!ba;/Ticket #1000:/p;g;ba};d' svn.log

svn日志检索查找特定单词的行之间
