击分割多行字符串由多字符定界符成阵列

Question

我已经寻找这里类似的话题，但大多数问题包括单字符分隔符。

我有文字的这个示例：

Some text here,
continuing on next lineDELIMITERSecond chunk of text
which may as well continue on next lineDELIMITERFinal chunk

和期望的输出是包含列表（extracted=()）：

1. Some text here,
   continuing on next line

2. Second chunk of text
   which may as well continue on next line

3. Final chunk

正如可以从样品中可以看出，“分隔符”作为分割符。

我曾尝试在SO含AWK众多样品，更换等。

Answer 1

如果你不想更改默认RS值，那么你可以请尝试以下。

awk '{gsub("DELIMITER",ORS)} 1' Input_file

Answer 2

您可以尝试使用数组。

#!/bin/bash
str="continuing on next lineDELIMITERSecond chunk of text
which may as well continue on next lineDELIMITERFinal chunk";


delimiter=DELIMITER
s=$str$delimiter

array=();
while [[ $s ]]; do
array+=( "${s%%"$delimiter"*}" );
s=${s#*"$delimiter"};
done;
declare -p array

这将文本分成根据您的分隔符阵的结果将是你的文字的数组。

阵列=（[0] =“继续上下一行” [1] = $“的文本\第二块nwhich不妨继续下一行” [2] =“最终块”）

可以使用阵列索引访问每一行或者可以打印用printf“％S \ N”中的所有行“$ {阵列[@]}”

其结果将是

继续对文本的下一行第二块可能还有继续下一行最后一块

该解决方案为您提供了一个机会，做了很多与你的文字。

Answer 3

你可以尝试这样的：

awk 'BEGIN {RS="DELIMITER";} {print}' input_file

然后将其分配给变量，等等。

Answer 4

随着AWK请尝试以下方法：

awk -v RS='^$' -v FS='DELIMITER' '{
    n = split($0, extracted)
    for (i=1; i<=n; i++) {
        print i". "extracted[i]
    }
}' sample.txt

其中收益率：

1. Some text here,
continuing on next line
2. Second chunk of text
which may as well continue on next line
3. Final chunk

如果你需要对AWK阵列转移到bash的阵列，将根据阵列上的后续工序需要进一步的步骤。

我认为在这个问题面临的最大挑战是要正确处理空间，换行，分隔符，然后把所有的东西在数组中。它是只拆分文件，那么这将是太容易了。这个怎么样模板：

#!/bin/bash
gencode(){
  echo -e "extracted=(); read -r -d '' item <<-DELIMITER"
  sed 's:DELIMITER:\n&\nextracted+=("$item"); read -r -d "" item <<-&\n:' Input_file;
  echo -e "DELIMITER\n"'extracted+=("$item")'
}
gencode|cat -n                                 # for explaination purpose only
eval "`gencode`"                               # do not remove "eval"
for (( i=0; i < ${#extracted[@]}; i++ )); do   # print results
  echo "$i: ${extracted[i]}"
done

输出

     1  extracted=(); read -r -d '' item <<-DELIMITER
     2  Some text here,
     3  continuing on next line
     4  DELIMITER
     5  extracted+=("$item"); read -r -d "" item <<-DELIMITER
     6  Second chunk of text
     7  which may as well continue on next line
     8  DELIMITER
     9  extracted+=("$item"); read -r -d "" item <<-DELIMITER
    10  Final chunk
    11  DELIMITER
    12  extracted+=("$item")
0: Some text here,
continuing on next line
1: Second chunk of text
which may as well continue on next line
2: Final chunk

Answer 6

您可以尝试的Perl。随着-0777选，PERL吸食整个文件到$ _变量。然后，您可以分割使用的分隔符的内容。看一下这个。

$ perl -0777 -ne '@x=split("DELIMITER");print join("\n\n",@x) ' hubbs.txt
Some text here,
continuing on next line

Second chunk of text
which may as well continue on next line

Final chunk

$

添加阵列位置在打印时

$ perl -0777 -ne '@x=split("DELIMITER"); for(@x) { print ++$i,". $_\n"  } ' hubbs.txt
1. Some text here,
continuing on next line
2. Second chunk of text
which may as well continue on next line
3. Final chunk
