r2e
R2E(1) General Commands Manual R2E(1)NAME
r2e - receive RSS feeds by email
SYNOPSIS
r2e [-d dir] action [options]
DESCRIPTION
r2e is a simple program which you can run in your crontab. It watches RSS feeds and sends you nicely formatted email message for each new
item.
The program is configured by ~/.rss2email/config.py by default. To use a different config file in a different directory, you can specify
the -d option before any actions.
For a quick start with r2e, try these steps:
r2e new your@address
r2e add http://feed.url/somewhere.rss
r2e run
The last command should eventually be put into your crontab, if you
want things be sent you automatically.
It is possible to use authenticated feeds using the following syntax:
r2e add http://user:password@example.com/feed
ACTIONS
new [youremail]
Create a new feedfile. If the second option is specified, it sets the default email address that mails are sent to.
add url [youremail]
Subscribe to a feed. The first option is the URL of the feed. The optional second option is the email address to send new items to.
Repeat for each feed you want to subscribe to.
run [--no-send] [num]
Scan the feeds and send emails for new items. This can be run in a cron job.
The --no-send option stops r2e from sending any email. This can be useful the first time you run it, as otherwise it would send every
available story.
If a number is specified, r2e will only download that feed. The list command lists the feed numbers.
email yournewemail
Change the default email address.
list List all your currently subscribed feeds.
delete n
Delete a feed, using its number from the list command.
pause n
Temporarily ignore a feed. A paused feed won't be updated at all.
unpause n
Re-enable updates from a feed.
opmlimport url
Import feeds from an OPML file.
opmlexport
Export feeds to standard output, as an OPML file.
CONFIGURATION
The program's behavior can be controlled via the ~/.rss2email/config.py config file. The file is a python file, so variables are set using
a syntax like this: VARIABLE = "value"
If the value is a number, the quotes may be omitted. Most configuration variables in the file are boolean values, where a 1 indicates the
option is set, and a 0 disables it.
See the example config.py file for a full list of available configuration variables.
FILES
~/.rss2email/feeds.dat
The database of feeds. Use r2e to add, remove, or modify feeds, do not edit it directly.
~/.rss2email/config.py
If this file exists, it it read to configure the program.
