Ron Yorston	ed9aa89269	wget: implement --post-file Add the --post-file option to send form data from a file. As with --post-data it's up to the user to ensure that the data is encoded as appropriate: all wget does is stuff the provided data into the request. The --post-data and --post-file options are mutually exclusive and only one instance of either may be given. Additionally: - update the usage message to include missing details of the --post-data and --header options; - free POST data if FEATURE_CLEAN_UP is enabled. function old new delta packed_usage 34158 34214 +56 wget_main 2762 2805 +43 .rodata 99225 99240 +15 static.wget_longopts 266 278 +12 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 4/0 up/down: 126/0) Total: 126 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>	2021-10-01 14:55:18 +02:00
