  Further Globus Options

Installing Globus

• You can install the Globus CLI by following the instructions found here.

• Or you can use the RIS developed Dockerimage for Globus CLI. Globus CLI Dockerimage

Login Into Globus CLI

• Once you have installed the Globus CLI or are using the Dockerimage, you will need to login. When using the dockerimage you will need to include the --no-local-server option and follow the directions it gives.

globus login

globus login --no-local-server

Globus CLI options

• Below is a list of some of the options available when using the Globus CLI.

Globus endpoint Command

• The endpoint command has many options, but the one that is most useful is the search option as you can use this option to search for the ID of an endpoint via name.

...

• The ID is the information that will be utilized in the other options.

Globus ls Command

• Once you have the ID of the endpoint you wish to use, you can use globus ls just like you use ls in linux/unix to display the files and directories in a directory.

• The Wash U RIS storage1 dtn1/dtn2 endpoints are the storage1 endpoints and will display what is in your storage1 directory. The following command demonstrates how to do that.

globus ls 01f0ac4c-9570-11ea-b3c4-0ae144191ee3:/storage1/fs1/wustlkey/Active/

Globus transfer Command

• Once you have determined the endpoints that you wish to use to transfer data, you can utilize the transfer command. You can transfer between the WashU endpoints to move data that way.

• There are three ways you can transfer data.

  • Transfer individual files.

  • Transfer a directory, using the recursive -r option.

  • Transfer files in bulk using the --batch option.

• Transfering an invdividual file.

...

• Transfering using the --batch option

  • You need to provide the directories that you are transferring between like with the transfer of a directory.

  • You need a space separated text file with the location of the files in the source endpoint followed by the location in the destination endpoint. Each file must have it’s own line.

  Code Block
  language python linenumbers false
  Sample1.txt Group1/Sample1.txt Sample2.txt Group1/Sample2.txt Sample3.txt Group1/Sample3.txt Sample4.txt Group2/Sample4.txt Sample5.txt Group2/Sample5.txt

  • With the batch method, you can sort files from the source into separate directories in the destination or pull files from separate directories in the source into one directory in the destination.

  Code Block
  language python linenumbers false
  Group1/Sample1.txt Sample1.txt Group1/Sample2.txt Sample2.txt Group2/Sample3.txt Sample3.txt Group2/Sample4.txt Sample4.txt Group2/Sample5.txt Sample5.txt

  • You can provide the file of the files you wish to transfer to the command with the < option.

  Code Block
  language python linenumbers false
  globus transfer --batch 01f0ac4c-9570-11ea-b3c4-0ae144191ee3:/path/to/source/location/my_directory 7e5cf228-8b33-11ea-bf85-0e6cccbb0103:/path/to/destination/location/my_directory < files_to_transfer.txt

Viewing Transfer and Task Information

Transfer Status

Given a transfer task ID, information about the status of the task can be retrieved with task show:

[user@host cwd]$ globus task show 543e219c-01c1-11eb-81a3-0e2f230cc907

Transferred Filenames

The task info command can also produce a list of successfully transferred files when the -t/--successful-transfers option is used:

...

Event and Failure Logs

Timing and activity information (including errors) can be obtained with task event-list:
