I'm stuck with a problem trying to output some sections of a rss feed to my conky program using curl and sed.
The rss feed is for tide times and I wish to output the times but not the rest to the conky desktop. To do this I need to pull out the four instances of times that are in the format of '00:00'. Since the digits will vary I have to match the sequence of two digits followed by a colon followed by two digits. This is what I tried so far:
Code:
#RSS Setup
URI=http://www.tidetimes.org.uk/southampton-tide-times.rss #URI of RSS Feed
LINES=1 #Number of headlines
#Environment Setup
EXEC="/usr/local/bin/curl -s" #Path to curl
TODAY=`date +%Y%m%d`
#Work Start
$EXEC $URI | grep description |\
sed -e 's/\([0-9]{2}:[0-9]{2}\)*/(&)/'
I have to admit my knowledge of sed is a bit shaky and the above has outputted a lot of gibberish. Any suggestions as to how I might pull out the four instances of the tide times in the format '00:00'?
