lute pathname of the transferred file.

In case of the chrooted FTP session this field can be

(the default interpretation) or as the one in the real
file system. The second type of interpretation can be
enabled by the command-line options of the ftpd(8).

fer. The set of possible values is:

a An ascii transfer.

is guided by ftpchroot(5) file).

(by convention it is an email address of the user).

able.
