$ ~/go/bin/skicka help                                                                                                             [45/2151]
skicka is a tool for working with files and folders on Google Drive.
See http://github.com/google/skicka/README.md for information about getting started.

usage: skicka [common options] <command> [command options]

Commands and their options are:
  cat        Print the contents of the Google Drive file to standard output.
             Arguments: drive_path ...

  download   Recursively download either a single file, or all files from a
             Google Drive folder to a local directory. If the corresponding
             local file already exists and has the same contents as the its
             Google Drive file, the download is skipped.
             Arguments: [-ignore-times] [-download-google-apps-files]
                        drive_path local_path

  df         Prints the total space used and amount of available space on
             Google Drive.

  du         Print the space used by the Google Drive folder and its children.
             Arguments: [drive_path ...]

  fsck       [EXPERIMENTAL/NEW] Use at your own risk.
             Perform a number of consistency checks on files stored in Google
             Drive, including verifying metadata and removing duplicate files
             with the same name.
             Arguments: [--trash-duplicates] [drive_path]

  help       Print this help text.

  genkey     Generate a new key for encrypting files.

  init       Create an initial ~/.skicka.config configuration file. (You
             will need to edit it before using skicka; see comments in the
             configuration file for details.)

  ls         List the files and directories in the given Google Drive folder.                                                                          [8/2151]
             Arguments: [-d, -l, -ll, -r] [drive_path ...],
             where -l and -ll specify long (including sizes and update
             times) and really long output (also including MD5 checksums),
             respectively.  The -r argument causes ls to recursively list
             all files in the hierarchy rooted at the base directory, and
             -d causes directories specified on the command line to be
             listed as files (i.e., their contents aren't listed.)

  mkdir      Create a new directory (folder) at the given Google Drive path.
             Arguments: [-p] drive_path ...,
             where intermediate directories in the path are created if -p is
             specified.

  rm         Remove a file or directory at the given Google Drive path.
             Arguments: [-r, -s] drive_path ...,
             where files and directories are recursively removed if -r is
             specified and the google drive trash is skipped if -s is
             specified. The default behavior is to fail if the drive path
             specified is a directory and -r is not specified, and to send
             files to the trash instead of permanently deleting them.

  upload     Uploads all files in the local directory and its children to the
             given Google Drive path. Skips files that have already been
             uploaded.
             Arguments: [-ignore-times] [-encrypt] [-follow-symlinks <maxdepth>]
                        local_path drive_path

Options valid for both "upload" and "download":
  -dry-run         Don't actually upload or download, but print the paths of
                   all files that would be transferred.
  -ignore-times    Normally, skicka assumes that if the timestamp of a local
                   file matches the timestamp of the file on Drive and the
                   files have the same size, then it isn't necessary to
                   confirm that the file contents match. The -ignore-times
                   flag can be used to force checking file contents in this
                   case.

General options valid for all commands:
  -config <filename>     General skicka configuration file. Default: ~/.skicka.config.
  -debug                 Enable debugging output.
  -dump-http             Dump http traffic.
  -metadata-cache-file <filename>
                         File to store metadata about Google Drive contents.
                         Default: ~/.skicka.metadata.cache
  -no-browser-auth       Disables attempting to open the authorization URL in a web
                         browser when initially authorizing skicka to access Google Drive.
  -quiet                 Suppress non-error messages.
  -tokencache <filename> OAuth2 token cache file. Default: ~/.skicka.tokencache.json.
  -verbose               Enable verbose output.
