There are two different ways to run shell commands in GitHub actions: the Literal Block Scalar (
run: |) and the Folded Block Scalar (
run: >). Here’s the difference.
literal block scalar
This one being
run: | where each line is treated as a separate command in the shell. For instance:
- name: Literal Block Scalar step run: | echo "first line" echo "second line" echo "third line"
Readable, maintainable, cleaner (IMO) and preserves formatting.
folded block scalar
Basically the lines are concatenated into a single one before being executed. Example:
- name: Folded Block Scalar step run: > echo "first command"; echo "second command"; echo "third command"
