Is there a way to make change in file but only if file exist ?  
For the moment the task stop with errors.

Example : the following task

> - name: “Paramétrages de suhosin pour php”  
> lineinfile:  
> dest=/etc/php5/apache2/conf.d/suhosin.ini  
> backup=yes  
> state=present  
> regexp=^{{ item.key }}  
> line=“{{ item.key }} {{ item.value }}”  
> insertafter=EOF  
> with\_items:
> - { key: ‘suhosin.post.max\_vars’, value: ‘5000’ }
> - { key: ‘suhosin.request.max\_vars’, value: ‘5000’ }
> - { key: ‘suhosin.perdir’, value: ‘pr’ }  
> notify:
> - restart apache

will fail if /etc/php5/apache2/conf.d/suhosin.ini don’t exist ie if php5-suhosin package is not installed

> failed: [127.0.0.1] =\> (item={‘value’: ‘5000’, ‘key’: ‘suhosin.post.max\_vars’}) =\> {“failed”: true, “item”: {“key”: “suhosin.post.max\_vars”, “value”: “5000”}, “rc”: 257}  
> msg: Destination /etc/php5/apache2/conf.d/suhosin.ini does not exist !  
> failed: [127.0.0.1] =\> (item={‘value’: ‘5000’, ‘key’: ‘suhosin.request.max\_vars’}) =\> {“failed”: true, “item”: {“key”: “suhosin.request.max\_vars”, “value”: “5000”}, “rc”: 257}  
> msg: Destination /etc/php5/apache2/conf.d/suhosin.ini does not exist !  
> failed: [127.0.0.1] =\> (item={‘value’: ‘pr’, ‘key’: ‘suhosin.perdir’}) =\> {“failed”: true, “item”: {“key”: “suhosin.perdir”, “value”: “pr”}, “rc”: 257}  
> msg: Destination /etc/php5/apache2/conf.d/suhosin.ini does not exist !

I’me about to use a pretask like this :

> - name: See if suhosin file exist
> 
> shell: “[-f ~/.oh-my-zsh] && echo ‘Found’ || echo ‘’”

> register: suhosin\_installed

Is there an another way ?
