如何处理从动态命令到创建目录的 For 循环中的白色 Space

Question

所以我有一个 for 循环，可以输出我想要的信息（OpenStack 项目列表），我希望它为我创建目录。然而，有时，人们用空格命名他们的项目，我需要考虑到这一点。这是我的命令的输出示例：

openstack project list

+----------------------------------+-----------------------------------------+

我的命令允许我实际仅为此指定名称：

openstack project list -c Name -f value

看起来像这样：

testing_grounds
Michaud
Ansible Automation
Sustaining Development
Data Center Services
MF-DevStack
Kubernetes Labs
mso-ems
Network Development
Data Engineering
Data Center Operations Service Scanning
admin
service
OpenStack-Example
Petes-place
Image Factory
Network Automation
Fault and Performance Management
Microseg
Development
Docker Enterprise
Application Architecture
casa-de-pedro

所以我考虑制作一个脚本来收集每个项目的所有资源，并将资源存储在以项目名称标记的目录中。所以我考虑包装一个 for 循环以创建以项目名称命名的目录。我尝试了以下方法，但没有奏效：

for i in $(openstack project list -c Name -f value); do mkdir -p -- 'echo $i'; done
for i in $(openstack project list -c Name -f value); do mkdir -p -- "$i"; done
for i in $(openstack project list -c Name -f value); do mkdir -p -- $i; done

none 似乎真的有效，而不是将它封装在一个字符串中，它不起作用，而是仍然将名称分开，如 Network Development 变成 Network 和 Development。我怎样才能让它工作，以便它能解释项目名称中可能存在的任何空格。

很遗憾，我无法使用常规的 for 循环语法来实现此目的。相反，我不得不使用 while 循环（非常感谢 Jetchisel 帮助我实现了这个结果）。以下方法对我有用：

[openstack_backup]$ while IFS= read -r name; do mkdir -p "$name"; done < <(openstack project list -c Name -f value)
[openstack_backup]$ ls
admin                     Data Center Operations Service Scanning  Docker Enterprise                 MF-DevStack  Network Automation   service
Ansible Automation        Data Center Services                     Fault and Performance Management  Michaud      Network Development  Sustaining Development
Application Architecture  Data Engineering                         Image Factory                     Microseg     OpenStack-Example    testing_grounds
casa-de-pedro             Development                              Kubernetes Labs                   mso-ems      Petes-place

你最好以 JSON 格式输出并用 jq

解析它

openstack project list --long -f json

或者使用更合适的语言，例如 python。
