Bash 使用sed抓取特定文本并排序+；输入回文件

我想请求一些帮助

我目前正在创建一个脚本，该脚本将有一个充满格式化文本的集合文件作为基础，然后根据用户输入从该文本文件中输入和删除。我会把这个放到bash脚本中

我已经找到了如何使用以下方法从文件中获取所需的文本：

sed -n '/5.1.1"/,/|}/p' textfile.txt

5.1.1是我的服务器的机架位置，我正在抓取文件的文本，直到它找到|}

这将输出以下内容：

|+  description = "5.1.1";
|-
|1: ~servername~ [4U];
|-
|5: servername [2U];
|-
|7: servername [2U];
|-
|9: servername [2U];
|-
|11: servername [2U];
|-
|15: servername [2U];
|-
|17: servername [2U];
|-
|19: servername [2U];
|-
|21: ~servername~ [2U];
|-
|23: servername [2U];
|-
|25: servername [2U];
|-
|29: servername [2U];
|-
|31: servername [2U];
|-
|33: servername [2U];
|-
|35: ~servername~ [2U];
|-
|37: ~servername";
|-
|39: servername;
|-
|41: switch;
|}

以此类推，直到5.1.15

sed只选择我需要更改的文本

我的想法是，使用sed获取文本，插入需要的行，然后根据第二列中的数字对其进行排序，然后将修改后的文本重新插入到相同位置的文件中，但是我不知道如何实现这一点

我将要输入的行与其他行的格式相同，然后我将在它下面输出一个|-

多谢各位

编辑1：

因此，期望的输出是：

我有第16行：servername；我想输入rack 5.1.1中的这个文件

从上面取得基础的最终结果是：

|+  description = "5.1.1";
|-
|1: ~servername~ [4U];
|-
|5: servername [2U];
|-
|7: servername [2U];
|-
|9: servername [2U];
|-
|11: servername [2U];
|-
|15: servername [2U];
|-
|16: servername;
|-
|17: servername [2U];
|-
|19: servername [2U];
|-
|21: ~servername~ [2U];
|-
|23: servername [2U];
|-
|25: servername [2U];
|-
|29: servername [2U];
|-
|31: servername [2U];
|-
|33: servername [2U];
|-
|35: ~servername~ [2U];
|-
|37: ~servername";
|-
|39: servername;
|-
|41: switch;
|}

我想我应该包括我写的用来格式化的脚本。它是不完整的，而且非常简陋，但是除了$location变量的if之外，它还起到了作用。为此，我需要修改正则表达式

#! /bin/bash


function serverread {

#Enter the location
function locationread { 
echo 'Enter the location of the server in the data center in format (x.x.x) ex. 5.1.15'
read location

if [[ "$location" =~ [0-9]{1,2}.[0-9]{1,2}.[0-9]{1,2} ]]
then
          echo "Success"
  else
            echo "You have entered an incorrect format for the rack, please try again."
            locationread
            exit
fi
}
locationread

echo Please enter the rack space at which the server was placed
read rp

if (( $rp < 1 || $rp > 42));
then
        echo You have entered an incorrect size for the server. Please enter a number between 1 and 42.
        read rp
else
{
        echo You entered: $rp as the server placement in the rack.
}
fi
#Enter the server name
echo Now please enter the server name "(Use ~ around the name if it is disconnected/unplugged)":
read name

if [[ $name == ~* ]] && [[ $name == *~ ]];
then
        echo "You entered: $name as the server name and it is currently disconnected in some way."
else
        echo "You entered: $name as the server name."
fi

#Enter the physical height of the server
echo Now please enter the size in height of the server:

function readsize {
read size
if [ $size -eq $size 2>/dev/null ]
then
        if (( $size < 1 || $size > 42));
        then
                echo You have entered an incorrect size for the server. Please enter a number between 1 and 42.
                readsize
        else
                echo "You entered: $size as the physical height of the server"
        fi
fi
}
readsize

#if (( $size == 1))
#
#  else
#                echo "$size is not an integer"
#        fi
#       
#if (( $size < 1 || $size > 42));
#then
#        echo You have entered an incorrect size for the server. Please enter a number between 1 and 42.
#        read size
#else
#        echo "You entered: $size as the physical height of the server"
#fi

if (( $size == 1));
then
        echo Currently this is the line that will be entered: $rp": "$name";"
else
        echo Currently this is the line that will be entered: $rp": "$name" ["$size"U];"
fi
echo Is this correct? '[yes/no]'
read matrix
echo Would you like to add another server? '[yes/no]'
read matrix2

if (( $matrix == "yes" ));
then
        if (( $matrix2 == "yes" ));
                then
                        serverread
        else
                        echo This is complete
                exit
        fi
else
        echo Please run this command again
        exit
fi
}
serverread

这就是我将如何完成你在另一个文件中向我展示的脚本：

#! /bin/bash

export $(cat rackformat | grep -v ^# | xargs)
echo $finale

while IFS= read -r l; do 
        if [[ "$l" =~ description ]]; then            
                msg="$l"$'\n';                 
        elif [[ "$l" =~ "}" ]]; then                    
                { 
                        echo -n "$msg" | grep -v '|-'; 
                        echo "\|$finale"; 
                } | sed 's/^|//' | sort -n | sed 's/^/|/' | while IFS= read -r l; do 
                echo "$l"; 
                echo '|-'; 
        done | head -n-1; 
        echo '|}'; 
else 
        msg+="$l"$'\n'; 
fi; 
done

对于以下输入：

|+  description = "5.1.1";
|-
|1: ~servername~ [4U];
|-
|5: servername [2U];
|-
|7: servername [2U];
|-
|9: servername [2U];
|-
|11: servername [2U];
|-
|15: servername [2U];
|-
|17: servername [2U];
|-
|19: servername [2U];
|-
|21: ~servername~ [2U];
|-
|23: servername [2U];
|-
|25: servername [2U];
|-
|29: servername [2U];
|-
|31: servername [2U];
|-
|33: servername [2U];
|-
|35: ~servername~ [2U];
|-
|37: ~servername";
|-
|39: servername;
|-
|41: switch;
|}

它的输出如下：

|+  description = "5.1.1";
|-
|1: ~servername~ [4U];
|-
|5: servername [2U];
|-
|7: servername [2U];
|-
|9: servername [2U];
|-
|11: servername [2U];
|-
|15: servername [2U];
|-
|16: servername;
|-
|17: servername [2U];
|-
|19: servername [2U];
|-
|21: ~servername~ [2U];
|-
|23: servername [2U];
|-
|25: servername [2U];
|-
|29: servername [2U];
|-
|31: servername [2U];
|-
|33: servername [2U];
|-
|35: ~servername~ [2U];
|-
|37: ~servername";
|-
|39: servername;
|-
|41: switch;
|}

由于您没有提供此文件格式的任何说明或其他示例，我假设：

  可以忽略和删除，并且永远不会更改（起初我以为这些是空的碎布，但后来它们介于15到16和17之间，所以不是）
• 本节以描述开头，以
