In a UNIX system I have a directory tree like
dir0/folder1/folder2/file1
dir1/folder1/folder2/file1
dir2/folder1/folder2/file1
dir3/folder1/folder2/file1
dir4/folder1/folder2/file1
...
Now I have got a newer version of file1 in dir0/folder1/folder2 and want to
ust it to replace every file1 above. Is there any command and/or program so
that I can finish my task using just one line (in reality I have more than 20
such directories)?
Thanks in advance!
