wget ERROR 400: Bad Request

Question

I have a list of URLs to be downloaded through wget. For a single file when I enter following command in shell it downloads and saves file correctly.

wget -O IPSL-CM5A-LR-tasmin-Historical-19500101-19501231.nc https://dataserver.nccs.nasa.gov/thredds/ncss/bypass/NEX-GDDP/bcsd/historical/r1i1p1/tasmin/IPSL-CM5A-LR.ncml?var=tasmin&north=55&west=72&east=136&south=16&horizStride=1&time_start=1950-01-01T12%3A00%3A00Z&time_end=1950-12-31T12%3A00%3A00Z&timeStride=1

However when I put use it in the following script for a list of URLs I get following error.

while read -r line; do wget -O $line; done < one_model.txt

Answer 1

The line in your script should work in a somewhat untidy way. Check that there are two fields in your file of URLs, first the output file and then the URL with a space separating the two.
