Shell Script Formatting (shfmt) FAQs

Question 1

How do I enforce formatting in my team?

Accepted Answer

The recommended approach is to commit a .shfmt.toml file to your repository and add a formatting check step (shfmt -d) to your CI/CD pipeline or a pre-commit hook.

Question 2

How does shfmt determine which configuration file to use?

Accepted Answer

shfmt follows a specific precedence: command-line flags override everything, followed by EditorConfig settings in the file's directory, and finally the .shfmt.toml file in the project root.

Question 3

Does shfmt support indentation with tabs?

Accepted Answer

Yes, to use tabs for indentation, set the indent value to 0 in your .shfmt.toml file or use the '-i 0' flag when running the command.

Question 4

Can I use this for shell scripts other than Bash?

Accepted Answer

Yes, shfmt supports POSIX Shell, Bash, mksh, and Bats. You can specify the dialect using the 'shell' key in your configuration or the '-ln' flag on the command line.

Question 5

What is the purpose of the binary-next-line option?

Accepted Answer

The binary-next-line option controls whether binary operators (like && or ||) appear at the end of a line or are moved to the start of the next line when a command is wrapped.
