.TH CURLOPT_WILDCARDMATCH 3 "May 18, 2018" "libcurl 7.73.0" "curl_easy_setopt options"
|
|
|
|
.SH NAME
|
|
CURLOPT_WILDCARDMATCH \- enable directory wildcard transfers
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_WILDCARDMATCH, long onoff);
|
|
.SH DESCRIPTION
|
|
Set \fIonoff\fP to 1 if you want to transfer multiple files according to a
|
|
file name pattern. The pattern can be specified as part of the
|
|
\fICURLOPT_URL(3)\fP 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
|
|
\fICURLOPT_FNMATCH_FUNCTION(3)\fP option.
|
|
|
|
A brief introduction of its syntax follows:
|
|
.RS
|
|
.IP "* - ASTERISK"
|
|
\&ftp://example.com/some/path/\fB*.txt\fP (for all txt's from the root
|
|
directory). Only two asterisks are allowed within the same pattern string.
|
|
.RE
|
|
.RS
|
|
.IP "? - QUESTION MARK"
|
|
Question mark matches any (exactly one) character.
|
|
|
|
\&ftp://example.com/some/path/\fBphoto?.jpeg\fP
|
|
.RE
|
|
.RS
|
|
.IP "[ - 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:
|
|
|
|
\fB[a-zA-Z0\-9]\fP or \fB[f\-gF\-G]\fP \- character interval
|
|
|
|
\fB[abc]\fP - character enumeration
|
|
|
|
\fB[^abc]\fP or \fB[!abc]\fP - negation
|
|
|
|
\fB[[:\fP\fIname\fP\fB:]]\fP class expression. Supported classes are
|
|
\fBalnum\fP,\fBlower\fP, \fBspace\fP, \fBalpha\fP, \fBdigit\fP, \fBprint\fP,
|
|
\fBupper\fP, \fBblank\fP, \fBgraph\fP, \fBxdigit\fP.
|
|
|
|
\fB[][-!^]\fP - special case \- matches only '\-', ']', '[', '!' or '^'. These
|
|
characters have no special purpose.
|
|
|
|
\fB[\\[\\]\\\\]\fP - escape syntax. Matches '[', ']' or '\\'.
|
|
|
|
Using the rules above, a file name pattern can be constructed:
|
|
|
|
\&ftp://example.com/some/path/\fB[a-z[:upper:]\\\\].jpeg\fP
|
|
.RE
|
|
