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!)
