Perl Write to file

This guide applies to servers running a standard setup (note, for shared hosting using "suexec" methods, see below). Typically, all files should be owned by your user (ftp) account on your web server, and should be writable by that account. On shared hosts, files should never be owned by the webserver process itself (sometimes this is www, or apache, or nobody user). Any file that needs write access from WordPress should be owned or group-owned by the user account used by wordPress (which may be different than the server account). For example, you may have a user account that lets you ftp files back and forth to your server, but your server itself may run using a separate user, in a separate usergroup, such as dhapache or nobody. If WordPress is running as the ftp account, that account needs to have write access,.

File position business pointers Both istream and ostream provide member functions for repositioning the file-position pointer. These member functions are seekg seek get for istream and seekp seek put for ostream. The argument to seekg and seekp normally is a long integer. A second argument can be specified to indicate the seek direction. The seek direction can be ios:beg (the default) for positioning relative to the beginning of a stream, ios:cur for positioning relative to the current position in a stream or ios:end for positioning relative to the end of a stream. The file-position pointer is an integer value that specifies the location in the file as a number of bytes from the file's starting location. Some examples of positioning the "get" file-position pointer are / position to the nth byte of fileObject (assumes ios:beg) ekg( n / position n bytes forward in fileObject ekg( n, ios:cur / position n bytes back from end of fileObject ekg( n, ios:end / position.
