BashBoiler: Safe Script Scaffolder
Generate clean, reliable bash script templates that incorporate essential best practices like error handling, argument parsing, and structured logging. Stop starting from scratch and failing silently.

# Click generate to create your script...Why Use This Boilerplate?
Writing a bash script often starts as a quick task but grows into a maintenance nightmare. Without proper safeguards, bash allows silent failures, uninitialized variables, and unpredictable behavior. BashBoiler solves this by providing a reliable foundation.
The "Strict Mode" Breakdown
The core of our boilerplate relies on "unofficial bash strict mode":
set -e: Instructs bash to immediately exit if any command has a non-zero exit status. This stops a script from continuing in an unknown state after a critical failure.set -u: Treats unset variables as an error. Overlooking variable initialization is a common source of catastrophic script behavior (e.g.,rm -rf /$UNSET_VAR/).set -o pipefail: Sets the exit code of a pipeline to that of the rightmost command to exit with a non-zero status. By default, bash only returns the status of the final command in a pipe, hiding intermediate failures.
Best Practices Included
When you select standard logging, the script sets up color-coded timestamped logs, ensuring output is readable whether executed manually or stored in CI/CD logs.
Proper argument parsing ensures that your script handles inputs predictably rather than relying blindly on positional arguments ($1, $2), which get confusing fast.
Finally, a `trap` for cleanup makes sure that temporary files or locks are removed even if the script crashes midway through execution.
