bash curl escape & in url
I'm running a curl command in bash, but the & in the middle causes the second half of the line to run in the background, here's what I'm trying to do:
Code:
lat="37.451"
lon="-122.18"
url="http://ws.geonames.org/findNearestAddress?lat=$lat&lng=$lon"
curl -s "$url"

I tried escaping the & with \&, but it doesn't work. I couldn't seem to get the right combination of quotes to work either. If I curl another url from the same site, it works. If I type this url in a browser, it returns the proper xml

wouldn't you want the url string to be wrapped in single-quotes...at the point of declaration...?
Code:
url='http://ws.geonames.org/findNearestAddress?lat=$lat&lng=$lon'
curl -s "$url"

or, better yet...
Code:
url="'http://ws.geonames.org/findNearestAddress?lat='${lat}'&lng='${lon}"
curl -s "$url"

or, actually:
Code:
url="$(echo 'http://ws.geonames.org/findNearestAddress?lat='${lat}'&lng='${lon} )"
curl -s "$url"

there was a typo in my last revision...$usrl is not the same as $url, believe it or not...

Sorry 'bout that...

Code:
-> lat="37.451"
lon="-122.18"

-> lon="-122.18"

-> url="'http://ws.geonames.org/findNearestAddress?lat='${lat}'&lng='${lon}"

-> echo $url                                                                
'http://ws.geonames.org/findNearestAddress?lat='37.451'&lng='-122.18

-> url='http://ws.geonames.org/findNearestAddress?lat='${lat}'&lng='${lon}  

-> echo $url                                                              
http://ws.geonames.org/findNearestAddress?lat=37.451&lng=-122.18

-> echo 'http://ws.geonames.org/findNearestAddress?lat='${lat}'&lng='${lon}
http://ws.geonames.org/findNearestAddress?lat=37.451&lng=-122.18

or
Code:
url="$(echo 'http://ws.geonames.org/findNearestAddress?lat='${lat}'&lng='${lon} )"
