can some one give me a few pointers on elif and bash.

[markp1989]

i want to wite a small script that will use curl to get the rss feed from the bbc site, check the current weather conditions, then change my background using feh.



#!/bin/bash -v
rm .weathertmp
curl http://feeds.bbc.co.uk/weather/feeds/rss/obs/world/0008.xml | tail -n 13 | head -n 1 |cut -f1 -d'.' > .weathertmp
if grep -qw rain .weathertmp ; then
echo Set background to rain
elif grep -qw cloud .weathertmp; then
echo set bacground to cloudy
elif grep -qw sunny; then
echo set background to sunny
else
echo other
fi


currently im just having the script echo what i want the background to be, untill i get the if statements sorted out.

it doesnt run right now, im not sure if it because i have more than one elif, or what.

wound some one be able to point me in the right direction.

edit: just relized what i had done wrong, i hadnt finished the final grep :@

Or you could try:


#!/bin/bash

weather=(rain cloudy sunny other)


for w in ${weather[@]}
do
grep -qw $w .weathertmp > /dev/null

if [ $? -eq 0 ]
then
echo set background to $w
break
fi
done
