CURLOPT_WILDCARDMATCH man page

CURLOPT_WILDCARDMATCH — enable directory wildcard transfers

Synopsis

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_WILDCARDMATCH, long onoff);

Description

Set onoff to 1 if you want to transfer multiple files according to a file name pattern. The pattern can be specified as part of the CURLOPT_URL(3) option, using an fnmatch-like pattern (Shell Pattern Matching) in the last part of URL (file name).

By default, libcurl uses its internal wildcard matching implementation. You can provide your own matching function by the CURLOPT_FNMATCH_FUNCTION(3) option.

A brief introduction of its syntax follows:

* - ASTERISK
ftp://example.com/some/path/*.txt (for all txt's from the root directory)
? - QUESTION MARK

Question mark matches any (exactly one) character.

ftp://example.com/some/path/photo?.jpeg

[ - BRACKET EXPRESSION

The left bracket opens a bracket expression. The question mark and asterisk have no special meaning in a bracket expression. Each bracket expression ends by the right bracket and matches exactly one character. Some examples follow:

[a-zA-Z0-9] or [f-gF-G] - character interval

[abc] - character enumeration

[^abc] or [!abc] - negation

[[:name:]] class expression. Supported classes are alnum,lower, space, alpha, digit, print, upper, blank, graph, xdigit.

[][-!^] - special case - matches only '-', ']', '[', '!' or '^'. These characters have no special purpose.

[\[\]\\] - escape syntax. Matches '[', ']' or '\'.

Using the rules above, a file name pattern can be constructed:

ftp://example.com/some/path/[a-z[:upper:]\\].jpeg
