Yestersay ive made a .diff file, and today I planned to apply the diff, but
unfortunately I dont know how to do it properly.

When I tried using the command patch -p0 -i ~/file/to/path it asks me for a “File to patch: “,
but I dont exactly know what he demands, because typing in the index wasnt helping.

Thank you in advance

patch -p0 -i ~/path/to/file
