Build Status

drive is a tiny program to pull or push Google Drive files.

drive was originally developed by Burcu Dogan while working on the Google Drive team. This repository contains the latest version of the code, as she is no longer able to maintain it.

Table of Contents

Requirements

go 1.3.X or higher is required. See here for installation instructions and platform installers.

  • Make sure to set your GOPATH in your env, .bashrc or .bash_profile file. If you have not yet set it, you can do so like this:
$ cat << ! >> ~/.bashrc
> export GOPATH=\$HOME/gopath
> export PATH=\$GOPATH:\$GOPATH/bin:\$PATH
> !
$ source ~/.bashrc # To reload the settings and get the newly set ones # Or open a fresh terminal

The above setup will ensure that the drive binary after compilation can be invoked from your current path.

Installation

To install from the latest source, run:

$ go get -u github.com/odeke-em/drive/cmd/drive

Otherwise:

  • In order to address issue #138, where debug information should be bundled with the binary, you'll need to run:
$ go get github.com/odeke-em/drive/drive-gen && drive-gen

In case you need a specific binary e.g for Debian folks issue #271 and issue 277

$ go get -u github.com/odeke-em/drive/drive-google

That should produce a binary drive-google

OR

To bundle debug information with the binary, you can run:

$ go get -u github.com/odeke-em/drive/drive-gen && drive-gen drive-google

Godep

  • Using godep
$ cd $GOPATH/src/github.com/odeke-em/drive/drive-gen && godep save
  • Unravelling/Restoring dependencies
$ cd $GOPATH/src/github.com/odeke-em/drive/drive-gen && godep restore

Please see file drive-gen/README.md for more information.

Platform Packages

For curated packages on your favorite platform, please see file Platform Packages.md.

Is your platform missing a package? Feel free to prepare / contribute an installation package and then submit a PR to add it in.

Configuration

Optionally set the GOOGLE_API_CLIENT_ID and GOOGLE_API_CLIENT_SECRET environment variables to use your own API keys.

Usage

Initializing

Before you can use drive, you'll need to mount your Google Drive directory on your local file system:

$ drive init ~/gdrive
$ cd ~/gdrive

De Initializing

The opposite of drive init, it will remove your credentials locally as well as configuration associated files.

$ drive deinit [--no-prompt]

For a complete deinit-ialization, don't forget to revoke account access, please see revoking account access

Pulling

The pull command downloads data that does not exist locally but does remotely on Google drive, and may delete local data that is not present on Google Drive. Run it without any arguments to pull all of the files from the current path:

$ drive pull

Pulling by matches is also supported

$ cd ~/myDrive/content/2015
$ drive pull --matches vines docx

To force download from paths that otherwise would be marked with no-changes

$ drive pull -force

To pull specific files or directories, pass in one or more paths:

$ drive pull photos/img001.png docs

Pulling by id is also supported

$ drive pull --id 0fM9rt0Yc9RTPaDdsNzg1dXVjM0E 0fM9rt0Yc9RTPaTVGc1pzODN1NjQ 0fM9rt0Yc9RTPV1NaNFp5WlV3dlU

Note: Checksum verification:

  • By default checksum-ing is turned off because it was deemed to be quite vigorous and unnecessary for most cases.

  • Due to popular demand to cover the common case in which size + modTime differences are sufficient to detect file changes. The discussion stemmed from issue #117.

    To turn checksum verification back on:

$ drive pull -ignore-checksum=false

drive also supports piping pulled content to stdout which can be accomplished by:

$ drive pull -piped path1 path2

Exporting Docs

By default, the pull command will export Google Docs documents as PDF files. To specify other formats, use the -export option:

$ drive pull -export pdf,rtf,docx,txt

To explicitly export instead of using --force

$ drive pull --export pdf,rtf,docx,txt --explicitly-export

By default, the exported files will be placed in a new directory suffixed by \_exports in the same path. To export the files to a different directory, use the -export-dir option:

$ drive pull -export pdf,rtf,docx,txt -export-dir ~/Desktop/exports

Supported formats:

  • doc, docx
  • jpeg, jpg
  • gif
  • html
  • odt
  • rtf
  • pdf
  • png
  • ppt, pptx
  • svg
  • txt, text
  • xls, xlsx

Pushing

The push command uploads data to Google Drive to mirror data stored locally.

Like pull, you can run it without any arguments to push all of the files from the current path, or you can pass in one or more paths to push specific files or directories.

Note: To ignore checksum verification during a push:

$ drive push -ignore-checksum

drive also supports pushing content piped from stdin which can be accomplished by:

$ drive push -piped path

  • Note:

    • In relation to #107 and numerous other issues related to confusion about clashing paths, drive will abort on trying to deal with clashing names. To turn off this safety, pass in flag --ignore-name-clash.

    • In relation to #57 and @rakyll's #49. A couple of scenarios in which data was getting totally clobbered and unrecoverable, drive now tries to play it safe and warn you if your data could potentially be lost e.g during a to-disk clobber for which you have no backup. At least with a push you have the luxury of untrashing content. To disable this safety, run drive with flag -ignore-conflict e.g:

      $ drive pull -ignore-conflict collaboration_documents

      Playing the safety card even more, if you want to get changes that are non clobberable ie only additions run drive with flag -no-clobber e.g:

      $ drive pull -no-clobber Makefile

    • Ordinarily your system will not traverse nested symlinks e.g:

      $ mkdir -p a/b
  $ mkdir -p ~/Desktop/z1/z2 && ls ~ > ~/Desktop/z1/z2/listing.txt
  $ ln -s ~/Desktop/z1/z2 a/b
  $ ls -R a # Should print only z2 and nothing inside it.

    However in relation to #80, for purposes of consistency with your Drive, traversing symlinks has been added.

For safety with non clobberable changes i.e only additions:

$ drive push -no-clobber
  • Due to the reasons above, drive should be able to warn you in case of total clobbers on data. To turn off this behaviour/safety, pass in the -ignore-conflict flag i.e:
$ drive push -force sure_of_content

To pull without user input (i.e. without prompt)

$ drive push -quiet

or

$ drive push -no-prompt

To get Google Drive to convert a file to its native Google Docs format

$ drive push -convert

Extra features: to make Google Drive attempt Optical Character Recognition (OCR) for png, gif, pdf and jpg files.

$ drive push -ocr

Note: To use OCR, your account should have this feature. You can find out if your account has OCR allowed.

$ drive features

Note:

  • MimeType inference is from the file's extension.

    If you would like to coerce a certain mimeType that you'd prefer to assert with Google Drive pushes, use flag -coerce-mime <short-key> See List of MIME type short keys for the full list of short keys.

$ drive push -coerce-mime docx my_test_doc
  • Excluding certain operations can be done both for pull and push by passing in flag --exclude-ops <csv_crud_values>

e.g

$ drive pull --exclude-ops "delete,update" vines
$ drive push --exclude-ops "create" sensitive_files
  • To show more information during pushes or pulls e.g show the current operation, pass in option --verbose e.g:
$ drive pull --verbose 2015/Photos content
$ drive push --verbose Music Fall2014

Publishing

The pub command publishes a file or directory globally so that anyone can view it on the web using the link returned.

$ drive pub photos
  • Publishing by fileId is also supported
$ drive pub --id 0fM9rt0Yc9RTPV1NaNFp5WlV3dlU 0fM9rt0Yc9RTPSTZEanBsamZjUXM

Unpublishing

The unpub command is the opposite of pub. It unpublishes a previously published file or directory.

$ drive unpub photos
  • Publishing by fileId is also supported
$ drive unpub --id 0fM9rt0Yc9RTPV1NaNFp5WlV3dlU 0fM9rt0Yc9RTPSTZEanBsamZjUXM

Sharing and Emailing

The share command enables you to share a set of files with specific users and assign them specific roles as well as specific generic access to the files. It also allows for email notifications on share.

$ drive share -emails odeke@ualberta.ca,odeke.ex@gmail.com -message "This is the substring file I told you about" -role writer -type group mnt/substringfinder.c projects/kmp.c

For example to share a file with users of a mailing list and a custom message

$ drive share -emails drive-mailing-list@gmail.com -message "Here is the drive code" -role group mnt/drive
  • Also supports sharing by fileId
$ drive share --emails developers@developers.devs --message "Developers, developers developers" --id 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 0fM9rt0Yc9kJRPSTFNk9kSTVvb0U

Unsharing

The unshare command revokes access of a specific accountType to a set of files.

$ drive unshare -type group mnt/drive
  • Also supports unsharing by fileId
$ drive unshare --type group --id 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 0fM9rt0Yc9kJRPSTFNk9kSTVvb0U

Touching

Files that exist remotely can be touched i.e their modification time updated to that on the remote server using the touch command:

$ drive touch Photos/img001.png logs/log9907.txt

For example to touch all files that begin with digits 0 to 9:

$ drive touch -matches $(seq 0 9)
  • Also supports touching of files by fileId
$ drive touch --id 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 0fM9rt0Yc9kJRPSTFNk9kSTVvb0U

Trashing and Untrashing

Files can be trashed using the trash command:

$ drive trash Demo

To trash files that contain a prefix match e.g all files that begin with Untitled, or Make

Note: This option uses the current working directory as the parent that the paths belong to.

$ drive trash -matches Untitled Make

Files that have been trashed can be restored using the untrash command:

$ drive untrash Demo

To untrash files that match a certain prefix pattern

$ drive untrash -matches pQueue photos Untitled
  • Also supports trashing/untrashing by fileId
$ drive trash --id 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 0fM9rt0Yc9kJRPSTFNk9kSTVvb0U
$ drive untrash --id 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 0fM9rt0Yc9kJRPSTFNk9kSTVvb0U

Emptying the Trash

Emptying the trash will permanently delete all trashed files. Caution: They cannot be recovered after running this command.

$ drive emptytrash

Deleting

Deleting items will PERMANENTLY remove the items from your drive. This operation is irreversible.

$ drive delete flux.mp4
$ drive delete --matches onyx swp
  • Also supports deletion by fileIds
$ drive delete --id 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 0fM9rt0Yc9kJRPSTFNk9kSTVvb0U

Listing Files

The list command shows a paginated list of files present remotely.

Run it without arguments to list all files in the current directory's remote equivalent:

$ drive list

Pass in a directory path to list files in that directory:

$ drive list photos

To list matches

$ drive list --matches mp4 go

The -trashed option can be specified to show trashed files in the listing:

$ drive list -trashed photos

To get detailed information about the listings e.g owner information and the version number of all listed files:

$ drive list -owners -l -version
  • Also supports listing by fileIds
$ drive list -depth 3 --id 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 0fM9rt0Yc9kJRPSTFNk9kSTVvb0U
  • Listing allows for sorting by fields e.g name, version, size, modtime, lastModifiedByMeTime lvt, md5. To do this in reverse order, suffix _ror-` to the selected key

e.g to first sort by modTime, then largest-to-smallest and finally most number of saves:

$ drive list --sort modtime,size_r,version_r Photos
  • For advanced listing
$ drive list --skip-mime mp4,doc,txt
$ drive list --match-mime xls,docx
$ drive list --exact-title url_test,Photos

Stating Files

The stat commands show detailed file information for example people with whom it is shared, their roles and accountTypes, and fileId etc. It is useful to help determine whom and what you want to be set when performing share/unshare

$ drive stat mnt

By default stat won't recursively stat a directory, to enable recursive stating:

$ drive stat -r mnt
  • Also supports stat-ing by fileIds
$ drive stat -r --id 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 0fM9rt0Yc9kJRPSTFNk9kSTVvb0U

OR

$ drive stat -depth 4 --id 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 0fM9rt0Yc9kJRPSTFNk9kSTVvb0U

Retrieving md5 Checksums

The md5sum command quickly retrieves the md5 checksums of the files on your drive. The result can be fed into the "md5sum -c" shell command to validate the integrity of the files on Drive versus the local copies.

Check that files on Drive are present and match local files:

~/MyDrive/folder$ drive md5sum | md5sum -c

Do a two-way diff (will also locate files missing on either side)

~/MyDrive/folder$ diff <(drive md5sum) <(md5sum *)

Same as above, but include subfolders

~/MyDrive/folder$ diff <(drive md5sum -r) <(find * -type f | sort | xargs md5sum)

Compare across two different Drive accounts, including subfolders

~$ diff <(drive md5sum -r MyDrive/folder) <(drive md5sum -r OtherDrive/otherfolder)

Note: Running the 'drive md5sum' command retrieves pre-computed md5 sums from Drive; its speed is proportional to the number of files on Drive. Running the shell 'md5sum' command on local files requires reading through the files; its speed is proportional to the size of the files.

New File

drive allows you to create an empty file or folder remotely Sample usage:

$ drive new --folder flux
$ drive new --mime-key doc bofx
$ drive new --mime-key folder content
$ drive new --mime-key presentation ProjectsPresentation
$ drive new --mime-key sheet Hours2015Sept
$ drive new --mime-key form taxForm2016 taxFormCounty
$ drive new flux.txt oxen.pdf # Allow auto type resolution from the extension

Quota

The quota command prints information about your drive, such as the account type, bytes used/free, and the total amount of storage available.

$ drive quota

Features

The features command provides information about the features present on the drive being queried and the request limit in queries per second

$ drive features

About

The about command provides information about the program as well as that about your Google Drive. Think of it as a hybrid between the features and quota commands.

$ drive about

OR for detailed information

$ drive about -features -quota

Help

Run the help command without any arguments to see information about the commands that are available:

$ drive help

Pass in the name of a command to get information about that specific command and the options that can be passed to it.

$ drive help push

To get help for all the commands

$ drive help all

Copying

drive allows you to copy content remotely without having to explicitly download and then reupload.

$ drive copy -r blobStore.py mnt flagging
$ drive copy blobStore.py blobStoreDuplicated.py
  • Also supports copying by fileIds
$ drive copy -r --id 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 0fM9rt0Yc9kJRPSTFNk9kSTVvb0U ../content

Rename

drive allows you to rename a file/folder remotely. To do so:

$ drive rename url_test url_test_results
$ drive rename openSrc/2015 2015-Contributions
  • Also supports renaming by fileId
$ drive rename 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 fluxing

Move

drive allows you to move content remotely between folders. To do so:

$ drive move photos/2015 angles library archives/storage
  • Also supports moving by fileId
$ drive move --id 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 0fM9rt0Yc9kJRPSTFNk9kSTVvb0U ../../new_location

DriveIgnore

drive allows you to specify a '.driveignore' file similar to your .gitignore, in the root directory of the mounted drive. Blank lines and those prefixed by '#' are considered as comments and skipped.

For example:

$ cat << $ >> .driveignore
> # My drive ignore file
> \.gd$
> \.so$
> \.swp$
> $

Note: Pattern matching and suffixes are done by regular expression matching so make sure to use a valid regular expression suffix.

DesktopEntry

As previously mentioned, Google Docs, Drawings, Presentations, Sheets etc and all files affiliated with docs.google.com cannot be downloaded raw but only exported. Due to popular demand, Linux users desire the ability to have *.desktop files that enable the file to be opened appropriately by an external opener. Thus by default on Linux, drive will create *.desktop files for files that fall into this category.

Command Aliases

drive supports a few aliases to make usage familiar to the utilities in your shell e.g:

  • cp : copy
  • ls : list
  • mv : move
  • rm : delete

Index Prune

  • index

If you would like to fetch missing index files for files that would otherwise not need any modifications, run:

$ drive index path1 path2 path3/path3.1 # To fetch any missing indices in those paths
$ drive index --id 0CLu4lbUI9RTRM80k8EMoe5JQY2z

You can also fetch specific files by prefix matches

$ drive index --matches mp3 jpg
  • prune

In case you might have deleted files remotely but never using drive, and feel like you have stale indices, running drive index --prune will search your entire indices dir for index files that do not exist remotely and remove those ones

$ drive index --prune
  • prune-and-index To combine both operations (prune and then fetch) for indices:
$ drive index --all-ops

Url

The url command prints out the url of a file. It allows you to specify multiple paths relative to root or even by id

$ drive url Photos/2015/07/Releases intros/flux
$ drive url --id  0Bz5qQkvRAeVEV0JtZl4zVUZFWWx  1Pwu8lzYc9RTPTEpwYjhRMnlSbDQ 0Cz5qUrvDBeX4RUFFbFZ5UXhKZm8

Open

The open command allows for files to be opened by the default file browser, default web browser, either by path or by id for paths that exist atleast remotely

$ drive open --file-browser=false --web-browser f1/f2/f3 jamaican.mp4
$ drive open --file-browser --id 0Bz8qQkpZAeV9T1PObvs2Y3BMQEj 0Y9jtQkpXAeV9M1PObvs4Y3BNRFk

Revoking Account Access

To revoke OAuth Access of drive to your account, when logged in with your Google account, go to https://security.google.com/settings/security/permissions and revoke the desired permissions

Uninstalling

To remove drive from your computer, you'll need to take out:

  • $GOPATH/bin/drive
  • $GOPATH/src/github.com/odeke-em/drive
  • $GOPATH/pkg/github.com/odeke-em/drive
  • $GOPATH/pkg/github.com/odeke-em/drive.a
  • Also do not forget to revoke drive's access in case you need to uninstall it.

Applying patches

To apply patches of code e.g in the midst of bug fixes, you'll just need a little bit of git fiddling.

For example to patch your code with that on remote branch patch-1, you'll need to go into the source code directory, fetch all content from the git remote, checkout the patch branch then run the go installation: something like this.

$ cd $GOPATH/src/github.com/odeke-em/drive
$ git fetch --all
$ git checkout patch-1
$ git pull origin patch-1
$ go get github.com/odeke-em/drive/cmd/drive

Why another Google Drive client?

Background sync is not just hard, it is stupid. Here are my technical and philosophical rants about why it is not worth to implement:

  • Too racy. Data is shared between your remote resource, local disk and sometimes in your sync daemon's in-memory structs. Any party could touch a file at any time. It is hard to lock these actions. You end up working with multiple isolated copies of the same file and trying to determine which is the latest version that should be synced across different contexts.

  • It requires great scheduling to perform best with your existing environmental constraints. On the other hand, file attribute have an impact on the sync strategy. Large files block -- you wouldn't like to sit on and wait for a VM image to get synced before you can start working on a tiny text file.

  • It needs to read your mind to understand your priorities. Which file do you need most? It needs to read your mind to foresee your future actions. I'm editing a file, and saving the changes time to time. Why not to wait until I feel confident enough to commit the changes remotely?

drive is not a sync daemon, it provides:

  • Upstreaming and downstreaming. Unlike a sync command, we provide pull and push actions. The user has the opportunity to decide what to do with their local copy and when they decide to. Make some changes, either push the file remotely or revert it to the remote version. You can perform these actions with user prompt:

      $ echo "hello" > hello.txt
  $ drive push # pushes hello.txt to Google Drive
  $ echo "more text" >> hello.txt
  $ drive pull # overwrites the local changes with the remote version

  • Allowing to work with a specific file or directory, optionally not recursively. If you recently uploaded a large VM image to Google Drive, yet only a few text files are required for you to work, simply only push/pull the exact files you'd like to worth with:

      $ echo "hello" > hello.txt
  $ drive push hello.txt # pushes only the specified file
  $ drive pull path/to/a/b path2/to/c/d/e # pulls the remote directory recursively

  • Better I/O scheduling. One of the major goals is to provide better scheduling to improve upload/download times.

  • Possibility to support multiple accounts. Pull from or push to multiple Google Drive remotes. Possibility to support multiple backends. Why not to push to Dropbox or Box as well?

Known issues

  • It probably doesn't work on Windows.
  • Google Drive allows a directory to contain files/directories with the same name. Client doesn't handle these cases yet. We don't recommend you to use drive if you have such files/directories to avoid data loss.
  • Racing conditions occur if remote is being modified while we're trying to update the file. Google Drive provides resource versioning with ETags, use Etags to avoid racy cases.
  • drive rejects reading from namedPipes because they could infinitely hang. See issue #208.
