Avoiding patch command to ask for 'File to patch:'

I am trying to patch a file.

The patch file is in the directory in which the list of files to be patched.

When I run commend

patch < file.patch

It prompts me

File to patch:

How to avoid this? What should I add in the patch file to automatically detect the filename that it should patch

GNU version of patch includes a --batch or -t option, which prevents all prompting.

-t or --batch
   Suppress  questions  like  -f, but make some different assumptions: skip patches
   whose headers do not contain file names (the same as -f); skip patches for which
   the file has the wrong version for the  Prereq: line in the patch; and assume
   that patches are reversed if they look like they are.

When creating the patch with diff, the output format, by default, does not includes the filename of the original filename. You can change this with the -u option like this...

$ diff -u OriginalFile NewFile >NewFile.patch

Then, you can simply...

$ patch -u <NewFile.patch

For further information, read about the unified GNU diff format.
