path 文件路径
block/content 添加的文本内容
state 删除absent ，默认present
insertbefore 在匹配的行前插入，=BOF，在文本前插入，默认是文本末尾
insertafter 在匹配的行后插入，=EOF，在文本后插入，默认是文本末尾
create =yes文件不存在就创建
marker 默认标记：# BEGIN ANSIBLE MANAGED BLOCK # END ANSIBLE MANAGED BLOCK
marker="#{mark}test（自定义）" 可以自定义标记名称

如果两次mark的标记相同，默认就是替换标记的内容
ansible jack6-2 -m blockinfile -a ‘path=/testdir/rc.local block="systemctl start mariadb\nsystemctl start httpd" insertafter=EOF‘

ansible jack6-2 -m blockinfile a ‘path=/testdir/rc.local block="systemctl stop mariadb\nsystemctl stop httpd" insertbefore=BOF marker=#{mark}service to start‘

ansible jack6-2 -m blockinfile -a ‘path=/testdir/test block="This is a test for add content" insertbefore="^This"‘

ansible jack6-2 -m blockinfile -a ‘path=/tmp/test block="Hello ansible,hi\nlineinfile\nEnsure a particular line is in a file,\nlineinfile -\nor replace an existing line using a back-referenced regular expression. " marker="#{mark} TEST FOR LINEINFILE" create=yes‘

lineinfile

path 文件路径
line 文本内容，替换或添加或删除的指定内容
regexp 正则匹配-------只处理最后一个匹配到的内容
insertbefore 和上个模块用法一样
insertafter 和上个模块用法一样
create=yes创建文件
state 和上个模块用法一样
backrefs 启用后向引用，就是类似sed的分组替换法

ansible jack6-2 -m lineinfile -a ‘path=/tmp/test line="test text"‘
ansible jack6-2 -m lineinfile -a ‘path=/tmp/test regexp="^line" line="I am a engine for IT"‘
ansible jack6-2 -m lineinfile -a ‘path=/tmp/test line="I am a engine for IT" state=absent‘
ansible jack6-2 -m lineinfile -a ‘path=/tmp/test line="I am Mr.wang" insertbefore="^Hello"‘
ansible jack6-2 -m lineinfile -a ‘path=/tmp/test regexp="(H.{4}).*(a.{4})" line="\2" backrefs=yes‘
