[Uppara venkat]

Hi all,

I'm written a play book to replace a string in multiple lines in a file but it not reflected, It has changed  in last line of a file.

not replace in multiple places.

- name: updating driver letter as in config file
  win_lineinfile:
    path: "{{ item.path }}"
    backrefs: true
    regexp: '-fileOverwrite_D'
     line: '-fileOverwrite_{{  target_disk|upper }}'
    state: present
  with_items:
      - "{{ result.files }}"  

The file of content is as below:

#Install
#-------
-fileOverwrite_D\:\\UCMDB\\UCMDBServer\\UninstallerData\\Uninstall_UCMDBServer.lax=Yes
-fileOverwrite_D\:\\UCMDB\\UCMDBServer\\UninstallerData\\resource\\iawin64_x64.dll=Yes
-fileOverwrite_D\:\\UCMDB\\UCMDBServer\\UninstallerData\\resource\\iawin32.dll=Yes
-fileOverwrite_D\:\\UCMDB\\UCMDBServer\\UninstallerData\\resource\\win64_32_x64.exe=Yes
-fileOverwrite_D\:\\UCMDB\\UCMDBServer\\UninstallerData\\resource\\remove.exe=Yes
-fileOverwrite_D\:\\UCMDB\\UCMDBServer\\UninstallerData\\resource\\invoker.exe=Yes
-fileOverwrite_D\:\\UCMDB\\UCMDBServer\\tools\\server\\custom-install.jar=Yes
-fileOverwrite_D\:\\UCMDB\\UCMDBServer\\content\\probe_patch\\probe-patch-11.4-windows.zip=Yes
-fileOverwrite_E\:\\UCMDB\\UCMDBServer\\content\\probe_installer\\UCMDB_DataFlowProbe_11.4.exe=Yes

I run the playbook it reflecting only last line of a file. 

Can you help me how to resolve this issue?
