Hi,
I am not sure whether I should ask this quesiton here. I am trying
'diff' and 'patch', and have encounter a problem.
I have create two directories as follows:
old
|-- musician
| `-- name
`-- writer
new
|-- musician
| `-- name
`-- writer
`-- name
Then, 'diff' is used to compare the two directories and generated a diff.
diff -Nru old new > patch.diff
Then, 'patch' is used to make 'old' identical to 'new'.
patch -p1 --dir old < patch.diff
In the following, I want to 'old' revert to its origin:
patch -p1 -R --dir old < patch.diff
The structruct of 'old' has turn to the following:
old
`-- musician
`-- name
It obvious that a subdirectory 'writer' has disappeared. I wonder some way
to keep 'writer' from being deleted. Thx.
