使用多字符定界符将字符串拆分为数组 [英] Split string into array using multi-character delimiter

问题描述

我需要将字符串拆分为数组.我的问题是分隔符是一个3个字符的分隔符: _-_
例如:

I need to split a string into an array. My problem is that the delimiter is a 3 character one: _-_
For example:

db2-111_-_oracle12cR1RAC_-_mariadb101

我需要创建以下数组:

db2-111
oracle12cR1RAC
mariadb101

类似的问题也遵循这种方法:

Similar questions followed this approach:

str="db2-111_-_oracle12cR1RAC_-_mariadb101"
arr=(${str//_-_/ })
echo ${arr[@]}

即使创建了数组，也无法正确地对其进行分割:

Even if the array is created, it has been split uncorrectly:

db2 
111 
oracle12cR1RAC 
mariadb101

似乎第一项中的-"字符导致数组的split函数失败.您可以提出解决方案吗?谢谢

It seems that the "-" character in the first item causes the array's split function to fail. Can you suggest a fix for it? Thanks

推荐答案

如果可以，请用另一个单字符替换 _-_ 序列字段拆分.例如，

If you can, replace the _-_ sequences with another single character that you can use for field splitting. For example,

$ str="db2-111_-_oracle12cR1RAC_-_mariadb101"
$ str2=${str//_-_/#}
$ IFS="#" read -ra arr <<< "$str2"
$ printf '%s\n' "${arr[@]}"
db2-111
oracle12cR1RAC
mariadb101
