[chuikingman]

Hi,

  I want to lock the file in linux and the file cannot be edit or modify by other .I know in perl, there is function flock , but it is not worked.

The file can be modifed and edit even if it is locked by flock .

Any other way to lock the file and so other cannot edit or modifed it ?

Any similar fucntion in perl ?

ltattr and chattr

I think its somewhat  related to the query what u are asking for.
