NAME

       Liferea - GTK desktop news aggregator

SYNOPSIS

       liferea [OPTIONS]

DESCRIPTION

       Liferea (Linux Feed Reader) is an aggregator for online news feeds.  It can be used to maintain a list of
       subscribed  feeds,  browse  and  search  through  their  items and displays their contents.  Additionally
       Liferea allows one to sync subscriptions and read headlines  with  online  accounts  of  TinyTinyRSS  and
       TheOldReader.

OPTIONS

       Liferea options:

       -v, --version
              Print version information and exit.

       -h, --help
              Display a option overview and exit.

       -a, --add-feed=URI
              Add a new subscription URI which can be a feed or website URL.

       -w, --mainwindow-state=STATE
              Start Liferea with its mainwindow in STATE: shown, hidden.

       -p, --disable-plugins
              Start with all plugins disabled.

       --debug-all
              Print debugging messages of all types.

DBUS INTERFACE

       To allow integration with other programs Liferea provides a DBUS interface for automatic creation of  new
       subscriptions.  The  script liferea-add-feed is a convenient way to use this interface. Just pass a valid
       feed URL as parameter and the feed will be added to the feed list. You can also pass non-feed URLs to use
       feed auto discovery.  See the EXAMPLES section.

ENVIRONMENT

       http_proxy (for HTTP connections)
       https_proxy (for HTTPS connections)
              If defined and a proxy is not specified in the Liferea preferences (which uses the proxy  settings
              provided  by  dconf),  their  value  will  be used as proxy URIs. Both are used by many common CLI
              tools, so make sure to export them in a dedicated subshell.

       LIFEREA_FEED_CMD_TIMEOUT
              If defined, overrides the default timeout for feed generating commands with the number of  seconds
              given  in  this  variable.  It  must be an integer value greater than zero; invalid values will be
              ignored.

       LIFEREA_UA_ANONYMOUS
              If defined, randomizes and anonymizes the default HTTP/S User-Agent string.

       LIFEREA_UA
              If defined, its value replaces the default HTTP/S User-Agent string.

       LIFEREA_UA has always precedence over LIFEREA_UA_ANONYMOUS, so the latter can be safely defined in global
       shell initialization files.

EXAMPLES

       $ http_proxy="http://proxy.example.com:3128" liferea
       $ http_proxy="http://username:password@proxy.example.com:3128" liferea
              Will alter each outgoing request to use proxy.example.com on port 3128 as proxy. If DNS resolution
              does not work, an IP address can be used instead.

       $ LIFEREA_UA_ANONYMOUS=1 liferea --debug-net
              Will alter each outgoing HTTP/S request to randomize Liferea's  version  and  hide  the  operative
              system in use.  In addition, prints the HTTP/S User-Agent and all outgoing network requests.

       $ LIFEREA_UA="Mozilla/5.0 (X11; Linux x86_64; rv:10.0) Gecko/20100101 Firefox/10.0" liferea
              Will alter each outgoing HTTP/S request to pose as Firefox on Linux.

       $ liferea-add-feed "feed:https://www.example.com/feed.rss"
       $ liferea --add-feed "https://www.example.com/feed.rss"
              Subscribe  to "example.com/feed.rss". Remember to supply a valid and correctly escaped feed URL as
              parameter. Please note that Liferea needs to be running for liferea-add-feed to work.
