SFEED(1) General Commands Manual SFEED(1)
NAME
sfeed – RSS and Atom parser
SYNOPSIS
sfeed [baseurl]
DESCRIPTION
sfeed reads RSS or Atom feed data (XML) from stdin. It writes the feed
data in a TAB-separated format to stdout. If the baseurl argument is a
valid absolute URL then the relative links or enclosures will be made an
absolute URL.
TAB-SEPARATED FORMAT FIELDS
The items are output per line in a TAB-separated format.
For the fields title, id and author each whitespace character is replaced
by a SPACE character. Control characters are removed.
The content field can contain newlines and these are escaped. TABs,
newlines and '\' are escaped with '\', so it becomes: '\t', '\n' and
'\\'. Other whitespace characters except spaces are removed. Control
characters are removed.
The order and content of the fields are:
1. timestamp UNIX timestamp in UTC+0, empty if missing or on a parse
failure.
2. title Title text, HTML code in titles is ignored and is
treated as plain-text.
3. link Link
4. content Content, can have plain-text or HTML code depending on
the content-type field.
5. content-type "html" or "plain" if it has content.
6. id RSS item GUID or Atom id.
7. author Item, first author.
8. enclosure Item, first enclosure.
9. category Item, categories, multiple values are separated by the
'|' character.
EXIT STATUS
The sfeed utility exits 0 on success, and >0 if an error occurs.
EXAMPLES
curl -s 'https://codemadness.org/atom.xml' | sfeed
To convert the character set from a feed that is not UTF-8 encoded the
iconv(1) tool can be used:
curl -s 'https://codemadness.org/some_iso-8859-1_feed.xml' |
iconv -f iso-8859-1 -t utf-8 |
sfeed
EXAMPLE SETUP
1. Create a directory for the sfeedrc configuration and the feeds:
mkdir -p ~/.sfeed/feeds
2. Copy the example sfeedrc(5) configuration:
cp sfeedrc.example ~/.sfeed/sfeedrc
$EDITOR ~/.sfeed/sfeedrc
Or import existing OPML subscriptions using sfeed_opml_import(1):
sfeed_opml_import < file.opml > ~/.sfeed/sfeedrc
3. To update feeds and merge the new items with existing items:
sfeed_update
4. Format feeds to a plain-text list:
sfeed_plain ~/.sfeed/feeds/*
Or format feeds to a curses interface:
sfeed_curses ~/.sfeed/feeds/*
There are also other formatting programs included. The README file has
more examples.

format it is not supported and the timezone is interpreted as UTC+0.
