假设一个3Kb文件，如下所示：
PdId1 Unit 1

Advanced Status OK

No errors found

PdId2 Unit 1

PdId3 Unit 1

No errors found
因此我们可以确定PdIdn可以可靠地用作分隔符，它始终位于一行的开头，并且它总是落后于数字。我想在“没有找到错误”的分隔符之间解析文本，如果字符串丢失，请抓住分隔符和接下来的四行（grep -A4），粘贴错误消息并回显结果。
我一直在讨论如何解决这个问题。我最喜欢Bash和grep，但我不认为grep会在这里削减它。我已经看过使用split来将文件分成几部分，但这看起来很麻烦，并且在处理完成后很难清理。我开始尝试在awk / sed中编写一些内容，但我不明白如何拆分分隔符，然后返回并解析每个结果，然后中断 next 并解析它。
我为这个问题的一般性质道歉，但我很难过，可以使用一些指导。
编辑：从技术上讲，PdId不是分隔符，而是下一条记录的开头。记录数是任意的。
编辑：我们现在可以使用真实世界数据：

逐行读取，将所需的行收集到累加器中，当看到触发消息时打印累积的行（否则只需重新开始并在看到下一条记录的开头时覆盖累加器）。
我们使用a作为累加器，使用辅助变量n来跟踪要累积的行数：
awk '/^PdId: [1-9][0-9]*/ { a=$0; n=4; next }
n { --n; a=a "\n" $ 0; next }
/No Errors Logged/ { print a }' file
答案 1 :(得分：0)
将以下内容放入可执行的awk文件中：
#!/usr/bin/awk -f
BEGIN {no_errs=1}
c > 0 {a[c++]=$0}
/^----------/ {
logAnyErrors()
ata_err=""
no_errs=0
c=1
delete a
}
/^No Errors Logged/ {no_errs=1}
/^ATA Error Count:/ {ata_err=$0}
function logAnyErrors() {
if( ata_err!="" || !no_errs) {
for(i=1;i<=5;i++) print a[i]
if( ata_err!="" ) print ata_err
print "--" # separator
}
}
END { logAnyErrors() }
您的数据实际上在每个PdId之前都有＆＃34; ^ ------------------＆＃34; ...的分隔符。
细分：
a的数组中，并使用行计数器c logAnyErrors()并重置计数器logAnyErrors()中，如果存在ATA或其他错误，请打印记录的前5行和分隔符，类似于我认为grep -A4的输出。当我将其放入名为awko的可执行文件并运行awko data时，我得到以下输出：
PdId: 4
Model Number: WD 1000
Drive Type: SATA
SMART Status: Enable
SMART Health Status: OK
ATA Error Count: 165 (device log contains only the most recent five errors)
----------------
对于某些问题，delete a行可能不符合要求。适用于我的Mac。除非您希望在发生错误时在每个块中打印出更多信息（因为前5行将始终被覆盖），所以没有必要。
