10.11.2 Inhibiting Keyboard Input
There are two ways you can prevent patch from asking you any
questions. The --force (-f) option assumes that you know
what you are doing. It causes patch to do the following:
- Skip patches that do not contain file names in their headers.
- Patch files even though they have the wrong version for the
‘Prereq:’ line in the patch;
- Assume that patches are not reversed even if they look like they are.
The --batch (-t) option is similar to -f, in that
it suppresses questions, but it makes somewhat different assumptions:
- Skip patches that do not contain file names in their headers
(the same as -f).
- Skip patches for which the file has the wrong version for the
‘Prereq:’ line in the patch;
- Assume that patches are reversed if they look like they are.
