How can I download multiple files stored in a text file with curl and xargs?

Solution 1:

Using GNU Parallel http://www.gnu.org/software/parallel/ you can do:

cat listfile.txt | parallel curl -O

Not only does GNU Parallel deal nicely with special chars like ' " and space, you will also get the added benefit of downloading in parallel.

Solution 2:

I found solution:

cat ./../c | xargs -n1 curl -O

xargs splits stdin by spaces and newlines, and passes to curl at once. So curl called only once with long arguments.

n1 option limits this passing argument count as 1, so curl will be called multiple times.
