Output Formatters

To allow for piping output to other utilies, the output of any command can be format as either TSV (Tab Seperated Values) or JSON.

JSON Output

# trello board list -o json
[{"name":"board1","id":"123456781234567812345678"},{"name":"board2","id":"876543218765432187654321"}]

This can be used with tools like jq to parse the data:

# trello board list -o json |jq '.[0] | {id}'
{
  "id": "123456781234567812345678"
}

TSV Output

# trello board list -o tsv
123456781234567812345678  board1
876543218765432187654321  board2

For example, you can grep out specific cards and then cut specific fields:

# trello board list -o tsv |grep board1 |cut -d$'\t' -f 1
123456781234567812345678

The default is currently set to output as legacy to match previous versions of the trello CLI. This will be changed to TSV or another human format in a future release.

Examples

List the boards available to the given credentials:

trello board list

List the lists for a given board id and output as a TSV list:

trello list list -b 123 -o tsv

Create a card and output as JSON:

trello card create -b 123 -l 321 -n 'card name' -d 'card description' -o json

Wrapper Script

If you find yourself adding the same arguments, it can be helpful to create a wrapper script. For example see trello.sh.
