Sequence expressions in wget and curl #
Given a range of JPGs to batch download:
http://example.com/manga/manga_06p01.jpgone approach using wget would be:
http://example.com/manga/manga_06p02.jpg
...
http://example.com/manga/manga_06p99.jpg
$ wget http://example.com/manga/manga_06p{00..99}.jpgBash 4 is required for brace expansion using a range. Unfortunately, the expression fails to expand at all when read from a file (e.g., $ wget -i urls.txt).
curl, on the other hand, does not depend on Bash for sequencing:
$ curl -O http://example.com/manga/manga_06_p[00-99].jpgso it will correctly parse sequences in a properly-formatted text file (e.g., urls.txt):
url = "http://example.com/manga/manga_06_p[00-99].jpg"like so:
url = "http://example.com/manga/manga_07_p[00-99].jpg"
url = "http://example.com/manga/manga_08_p[00-99].jpg"
$ curl --remote-name-all -K urls.txt
