lftp.conf - the global configuration file for lftp
the /etc/lftp.conf configuration file changes the default behavior of lftp and
affects the settings for all users. User-specific options should be set in
either the ~/.lftprc or ~/.lftp/rc file. These configuration files are read
when lftp starts up and the parameters defined therein take affect at that
time.
In addition to lftp's configuration options, aliases and 'set'
commands can be defined in any of these configuration files. Refer to the
Command and Settings sections of the lftp man page for more details.
