prePEND消息rsstail [英] Prepend message to rsstail

问题描述

我试图prePEND一条消息rsstail的输出，这就是我现在：

  rsstail -o -i 15 --initial 0 http://feeds.bbci.co.uk/news/world/europe/rss.xml | AWK -v时间= $（日期+ \\ [％H：％M：％S_％D /％M /％Y \\]）'{打印时间，$ 0}'|三通someFile.txt
 

这应该给我以下内容：

  [23：46：49_23 /二千零十四分之十]标题：someTitle
 

命令后，我有一个 |而读线做...结束永远也不会被调用，因为上面的命令没有输出一个单一的东西。我在做什么错了？

PS：我使用的rsstail的Python版本，因为另外一个劲儿地崩溃（的https：/ /github.com/gvalkov/rsstail.py ）

编辑：

由于在评论中要求的命令：

  rsstail -o -i 15 --initial 0 http://feeds.bbci.co.uk/news/world/europe/rss.xml
 

会给回这样的消息下，当一个新的文章中找到

 标题：瑞典要求关闭搜索子
 

解决方案

看来，我的 rsstail 和你不一样，但我支持选项

  -Z加上x标题X
 

让

  rsstail -Z$（日期+ \\ [％H：％M：％S_％D /％M /％Y \\]）...
 

做工作，而不 AWK ;在另一方面，你确实有一些问题，缓冲，这可能要问 rsstail 标题给定数目后停止？

I am trying to prepend a message to the output of rsstail, this is what I have right now:

rsstail -o -i 15 --initial 0 http://feeds.bbci.co.uk/news/world/europe/rss.xml | awk -v time=$( date +\[%H:%M:%S_%d/%m/%Y\] ) '{print time,$0}' | tee someFile.txt

which should give me the following:

[23:46:49_23/10/2014] Title: someTitle

After the command I have a | while read line do ... end which never gets called because the above command does not output a single thing. What am I doing wrong?

PS: I am using the python version of rsstail, since the other one kept on crashing (https://github.com/gvalkov/rsstail.py)

EDIT:

As requested in the comments the command:

rsstail -o -i 15 --initial 0 http://feeds.bbci.co.uk/news/world/europe/rss.xml

Will give back a message like the following when a new article is found

Title: Sweden calls off search for sub

解决方案

It seems that my rsstail is different from yours, but mine supports the option

-Z x    add heading 'x'

so that

rsstail -Z"$( date +\[%H:%M:%S_%d/%m/%Y\] ) " ...

does the job without awk; on the other hand, you do have some problem with buffering, is it possible to ask rsstail to stop after a given number of titles?
