Bash 如果遇到特定单词，请删除awk中的块,bash,sed,awk,Bash,Sed,Awk,我想使用awk只打印出Start和End行之间没有单词complete的块我是根据以前的文章写这部分的，但问题是我的行不是以start和end开头的。我可以交换它们，并把这些记录放在行首，但如果有人知道另一种选择，那将不胜感激。谢谢大家! 下面是如何在awk cat file Hello Start some data more End Data Start Yes Here is more This is incomplete Not my day End 如果不包含不完整一些更具

我想使用

awk

只打印出

Start

和

End

行之间没有单词

complete

的块

我是根据以前的文章写这部分的，但问题是我的行不是以

start

和

end

开头的。我可以交换它们，并把这些记录放在行首，但如果有人知道另一种选择，那将不胜感激。谢谢大家!

下面是如何在

awk

cat file
Hello
Start
some data
more
End
Data
Start
Yes
Here is more
This is incomplete
Not my day
End

如果不包含

不完整

一些更具可读性的：

awk '
    $0~start    {                       # If `Start` is found, do:
                f=1}                    # Set flag `f` to `1`
    f           {                       # If flag `f` is true do:
                s=s?s"\n"$0:$0          # Create block of data. (Take care of start correctly)
                if ($0~/incomplete/)    # If line does contain `incomplete` do:
                    f=s=0}              # Clear block of data `s` and clear flag `f`
    $0~end && f {                       # If `End` is found and flag `f` is true, do:
                print s                 # Print block of data `s`
                f=s=0}                  # Clear block of data `s` and clear flag `f`
    ' start="$start" end="$end"         # Read `start` and `stop` from variable
    file                                # Name of input file

你的输入看起来是什么样子的？告诉我们两个你的块没有开始和结束的单词并不是特别有用。你大概可以猜到什么是有用的。。。

cat file
Hello
Start
some data
more
End
Data
Start
Yes
Here is more
This is incomplete
Not my day
End

awk '/Start/ {f=1} f {s=s?s"\n"$0:$0;if ($0~/incomplete/) f=s=0} /End/ && f {print s;f=s=0}' file
Start
some date
more
End

awk '
    $0~start    {                       # If `Start` is found, do:
                f=1}                    # Set flag `f` to `1`
    f           {                       # If flag `f` is true do:
                s=s?s"\n"$0:$0          # Create block of data. (Take care of start correctly)
                if ($0~/incomplete/)    # If line does contain `incomplete` do:
