dave – DAV Explorer

Synopsis

 dave [OPTIONS] URL

E.g.

Description

dave is a powerful command-line program for interacting with WebDAV-enabled webservers. With dave you can:

•

get and put files

•

make directories on a remote webserver

•

remove files and directories from a remote webserver

•

edit a file on the webserver with a single command

•

recursively get a remote directory

•

recursively put a local directory

•

lock and unlock remote files and directories

•

securely transfer over https

•

authenticate using the safer Digest authentication

Dave is a part of the PerlDAV project (http://www.webdav.org/perldav/) and is built on top of the HTTP::DAV perl API.

If you would like to script webdav interactions in Perl checkout the HTTP::DAV API as it’s commands are the basis for dave’s.

Options

"-debug N"

Sets the debug level to N. 0=none. 3=noisy.

"-h"

Prints basic help and options.

"-man"

Prints the full manual (equivalent to perldoc dave).

You will need to use a pager like "more" or "less". e.g.

 dave -man |less

"-p <password>"

Sets the password to be used for the URL. You must also supply a user. See "-u".

"-u <username>"

Sets the username to be used for the URL. You must also supply a pass. See "-p".

"-tmpdir /some/path"

Create temporary files in "/some/path" instead of the default "/tmp".

Commands

cd URL

changes directories

 dave> open host.org/dav_dir/

 dave> cd dir1

 dave> cd ../dir2

cat URL

shows the contents of a remote file

 dave> open host.org/dav_dir/

 dave> cat index.html

Note: you cannot cat a directory (collection).

cp

copy SOURCE_URL DEST_URL

copies one remote resource to another

 dave> open host.org/dav_dir/

Create a copy of dir1/ as dav2/

 dave> cp dir1 dav2

Create a copy of dir1/file.txt as dav2/file.txt

 dave> cd dir1

 dave> copy file.txt ../dav2

Create a copy of file.txt as ../dav2/new_file.txt

 dave> copy file.txt dav2/new_file.txt

Aliases: cp

rmdir URL

rm URL

delete URL

deletes a remote resource

 dave> open host.org/dav_dir/

 dave> delete index.html

 dave> rmdir ./dir1

 dave> delete /dav_dir/dir2/

 dave> delete /dav_dir/*.html

This command recursively deletes directories. BE CAREFUL :)

This command supported wildcards (globbing). See get.

Aliases: rm, rmdir

edit URL

edits the contents of a remote file

 dave> open host.org/dav_dir/

 dave> edit index.html

Edit is equivalent to the following sequence of commands:

 LOCK index.html (if allowed)

 GET index.html /tmp/dave.perldav.421341234124

 sh $EDITOR /tmp/dave.perldav.421341234124

 PUT index.html (if modified)

 UNLOCK index.html (if locked)

Where $EDITOR is determined from the environment variables DAV_EDITOR or EDITOR.

If DAV_EDITOR is set, it will use that, otherwise it will use EDITOR. If neither variables are set, then “vi” will be used.

Notes:

The lock only lasts for 10 hours.

You cannot edit a directory (collection).

The temporary save directory is editable by editing dave and changing TMP_DIR

get URL [FILE]

downloads the file or directory at URL

If FILE is not specified it will be saved to your current working directory using the same name as the remote name.

 dave> open host.org/dav_dir/

Recursively get remote my_dir/ to .

 dave> get my_dir/

Recursively get remote my_dir/ to /tmp/my_dir/

 dave> get my_dir /tmp

Get remote my_dir/index.html to /tmp/index.html

 dave> get /dav_dir/my_dir/index.html /tmp

Get remote index.html to /tmp/index1.html

 dave> get index.html /tmp/index1.html

Use globs and save to /tmp

 dave> get index* /tmp # Gets index*.html, index*.txt, etc.

 dave> get index*.html /tmp/index1.html # Gets index*.html

 dave> get index[12].htm? # Gets file1 and file2, .htm and .html

? [CMD]

h [CMD]

help [CMD]

prints list of commands or help for CMD

 dave> ?

 dave> help get

Aliases: ?, h

lcd [DIR]

changes local directory

 dave> lcd /tmp

lls [DIR]

lists local directory contents

 dave> lcd /tmp

 dave> lls

 dave> lls /home

This command simply execs the local ls command and is equivalent to “!ls”

dir [URL]

ls [URL]

lists remote directory contents or file props

 dave> ls

 Locks supported: write/exclusive write/shared

 Locks:

Use propfind to get a similar printout of a collection (directory).

Aliases: dir

lock [URL [TIMEOUT] [DEPTH]]

locks a resource

Without a URL you will lock the current remote collection.

TIMEOUT can be any of the following formats:
       30s          30 seconds from now
       10m          ten minutes from now
       1h           one hour from now
       1d           tomorrow
       3M           in three months
       10y          in ten years time
       2000-02-31 00:40:33
       2000-02-31

Default is an infinite timeout

See perldoc "HTTP::DAV::Resource" for more information about timeouts.

DEPTH can be either “0” or “infinity” (default)

Seeting the lock Scope and Type is not currently implemented. Let me know if you need it as it shouldn’t be too much effort.

mkdir URL

mkcol URL

make a remote collection (directory)

 dave> open host.org/dav_dir/

 dave> mkcol new_dir

 dave> mkdir /dav_dir/new_dir

Aliases: mkdir

mv

 Locks:

Using ls will get you the same printout if you ls a file. But ls’ing a collection will show you the collections contents.

If URL is an existing collection then the dir/file will be copied INTO that collection.

Getting Help

The perldav mailing list There is a mailing list for PerlDAV and dave for use by Developers and Users. Please see http://mailman.webdav.org/mailman/listinfo/perldav

Installation

dave is installed to /usr/local/bin by default when you install the PerlDAV library. See http://www.webdav.org/perldav/ for installation details of PerlDAV.

What Platforms Will It Work On?

dave is pure perl so only needs Perl5.003 (or later) and the "PerlDAV" library to be installed.

I have not ported dave to Windows but would like somebody to have a shot at it.
