Using Files in Workflows

​

File object

1. identifier, which is the unique identifier of the file.
   • This field is used in various actions including upload file or send file via Slack.
2. size, which is the size of the file in bytes.
3. path, which is the absolute path to the file:
   • This field can be used in Bash/Python steps when you want to perform some action on the file (e.g. if you want to print the file in Bash, you can run the cat command and use the file path as the argument).

​

Expression Language and Variable Picker Support

1. To access the File Identifier, File Path and the File Size, use the variable picker under the files
2. Select WorkingDirectory under the file section of the Variable Picker.

3. Then choose WorkingDirectory|identifier, WorkingDirectory|path or WorkingDirectory|size according to the respective inputs.

4. Blink’s Expression Language supports accessing the file objects using the get_file function.

{{get_file("WorkingDirectory").identifier}}

• It returns an object containing the 3 fields: the files identifier, path and size
