= Deleting sticky files from clients = Sticky files can be deleted in either of two ways. == Regular expression matching == You can create a file '''file_delete_regex''' in your project directory, containing a list of regular expressions, one per line. If a client has a sticky file whose name matches any of these expressions, it will be instructed to delete the file. == Explicit deletion == To delete a sticky file from a particular host, use the function {{{ delete_file(int host_id, const char* file_name) }}} or the command line program (run from the project root dir) {{{ delete_file -host_id X -file_name Y }}} `delete_file()` creates a message for the specific host and adds it to the `msg_to_host` table. This message instructs the client to delete the file. The message is included in the next scheduler reply to the host. The message XML has the form {{{ file_name }}} For this to work, you need to include {{{}}} in [ProjectOptions#client-control config.xml].
