200 def getSynopsis(self):
201 return "Usage: tahoe [options] cp FROM.. TO"
203 Use 'tahoe cp' to copy files between a local filesystem and a Tahoe grid.
204 Any FROM/TO arguments that begin with an alias indicate Tahoe-side
205 files or non-file arguments. Directories will be copied recursively.
206 New Tahoe-side directories will be created when necessary. Assuming that
207 you have previously set up an alias 'home' with 'tahoe create-alias home',
208 here are some examples:
210 tahoe cp ~/foo.txt home: # creates tahoe-side home:foo.txt
212 tahoe cp ~/foo.txt /tmp/bar.txt home: # copies two files to home:
214 tahoe cp ~/Pictures home:stuff/my-pictures # copies directory recursively
216 You can also use a dircap as either FROM or TO target:
218 tahoe cp URI:DIR2-RO:j74uhg25nwdpjpacl6rkat2yhm:kav7ijeft5h7r7rxdp5bgtlt3viv32yabqajkrdykozia5544jqa/wiki.html ./ # copy Zooko's wiki page to a local file
220 This command still has some limitations: symlinks, special files (device
221 nodes, named pipes), and non-ASCII filenames are not handled very well.
222 Arguments should probably not have trailing slashes. 'tahoe cp' does not
223 behave as much like /bin/cp as you would wish, especially with respect to

243 the grid, e.g., 'tahoe mv alias:some_file alias:new_file'.
245 If moving a remote file into a remote directory, you'll need to append a
246 '/' to the name of the remote directory, e.g., 'tahoe mv tahoe:file1
247 tahoe:dir/', not 'tahoe mv tahoe:file1 tahoe:dir'.
249 Note that it is not possible to use this command to move local files to
250 the grid -- use 'tahoe cp' for that.
