deleting file

RouterOS Scripting
1

Hi,

How can I check if file exists before deleting it?

If I issue:

/file remove [/file find name=conf_ok_if_alias.rsc]

and the file doesnt exist, I got an error which exits my script.

Thank you.

:local check [/file find name=conf_ok_if_alias.rsc]
:if ( $check != "" ) do= {
     /file remove $check;
}
