我正试图将一个小的bash代码片段转换为Ansible，但我发现它很难实现。基本上，它首先检查/etc/redhat-release是否存在。如果是，则它正在查找正则表达式模式*release 6.8*。如果找到该模式，则它正在检查另一个文件/bin/login.ori。如果它存在，那么它将执行几个操作。
#fixed RHEL6.8/CentOS6.8 rlogin issue
if [ -f /etc/redhat-release ]; then
case `cat /etc/redhat-release` in
*'release 6.8'*)
if [ ! -e /bin/login.ori ]; then
cp -f
/bin/login /bin/login.ori
cp -f $MDIR/login.bin.68 /bin/login
restorecon /bin/login
fi
;;
esac
fi
以下是我迄今为止所尝试的：
- name: Fix RHEL6.8/CentOS6.8 rlogin issue
stat:
path: /etc/redhat-release
register: redhat_file
- debug:
msg: "File exists: {{ redhat_file }}"
when: redhat_file.stat.exists
- name: Check whether /etc/redhat-release contains "*release 6.8*"
lineinfile:
path: /etc/redhat-release
line: '*release 7.3*'
# insertafter: [main]
register: checkmyconf
when: redhat_file.stat.exists
- name: Greet the world if /etc/redhat-release contains "*release 6.8*"
debug:
msg: "{{ checkmyconf }}"
when: checkmyconf.stdout | match('*release 7.3.1611*')
但我的错误越来越少。请帮忙。

注意：我已经尝试了此链接中的所有建议，但它不适用于此用例，因为我的用例中的line属性是动态的。
这是等效的
