मैं इस पैच को लागू करना चाहूंगा, इसलिए मैंने "इंडेक्स: src / options.h" पर कोड की शुरुआत की और "+ @ आइटम" के साथ समाप्त किया और इसे wget's स्रोत कोड फ़ोल्डर में बनाई गई एक नई फ़ाइल में डाल दिया । फिर मैंने किया:
$ patch -p0 < name_of_patch
(Patch is indented 1 space.)
patching file src/options.h
patch: **** malformed patch at line 6: char **excludes; /* List of excluded FTP directories. */
मुझे यह कैसे लागू करना चाहिए?
यह मेरे द्वारा बनाई गई फ़ाइल की सामग्री है:
