读取nul分隔字段 [英] read nul delimited fields

问题描述

提供此文件

printf 'alpha\0bravo\0charlie' > delta.txt

我想将字段读入单独的变量.我使用的原因空分隔符是因为字段将包含文件路径，该文件路径可以包含除null外的任何字符.我尝试了以下命令:

I would like to read the fields into separate variables. The reason I am using a null separator is because the fields will contain file paths, which can contain any character except null. I tried these commands:

IFS= read mike november oscar < delta.txt
IFS=$'\0' read mike november oscar < delta.txt

但是字段没有正确分割

$ echo $mike
alphabravocharlie

推荐答案

作为一种解决方法，我创建了此函数

As a workaround, I created this function

function read_loop {
  while [ "$#" -gt 0 ]
  do
    read -d '' "$1"
    shift
  done
}

示例用法

read-nul mike november oscar < delta.txt
