checking wget's return value [if]

Question

I\'m writing a script to download a bunch of files, and I want it to inform when a particular file doesn\'t exist.

r=`wget -q www.someurl.com`
if [ $r -ne 0          


        

Answer 1

$r is the text output of wget (which you've captured with backticks). To access the return code, use the $? variable.
