Command Line Tool

perl client for the Swift API. a command-line script (swift.pl).

setup openstack environments

    $ export OS_AUTH_VERSION='1.0' # default 2.0
    $ export OS_AUTH_URL='https://*******'
    $ export OS_TENANT_NAME='*******'
    $ export OS_USERNAME='*******'
    $ export OS_PASSWORD='************'

cli examples

    $ swift.pl put container1
    $ swift.pl put container1 hello.txt (upload file)
    $ swift.pl list
    $ swift.pl list container1
    $ swift.pl list container1/hello.txt
    $ swift.pl get container1/hello.txt > hello.txt (download file)
    $ swift.pl delete container1/hello.txt
    $ swift.pl delete container1
    $ swift.pl delete 'container1/*'  (require quoting!)
    $ swift.pl post static '{"X-Container-Read":".r:*"}'

multi cpu support (parallel downloads and uploads)

    $ swift.pl donwload 'container1/*' (require quoting!)
    $ swift.pl upload 'container1/*' (require quoting!)

creating a .swift.pl.conf file in the user's home directory

    $ cat .swift.pl.conf 
    timeout=200
    user_agent=perl Net::OpenStack::Swift
    workers=8
    os_auth_url=
    os_tenant_name=
    os_username=
    os_password=

Debug

To print request/response Debug messages, $ENV{LM_DEBUG} must be true.

example

    $ LM_DEBUG=1 carton exec perl test.pl
