Bash Boilerplate Generator

Generate a production-ready bash script template with error handling, logging, and argument parsing.

How to use the Bash Boilerplate Generator

  1. 1Toggle the features you need: strict error handling (set -euo pipefail), logging, argument parsing, or --help output.
  2. 2Enter your script name and a one-line description — these appear in comments and the --help text.
  3. 3Click "Generate Script" to get the complete .sh template in the output panel.
  4. 4Copy the script, save as yourscript.sh, run `chmod +x yourscript.sh`, and replace the placeholder logic with your own.

Frequently Asked Questions

What does `set -euo pipefail` do in bash?

`set -e` exits the script immediately on any command error. `set -u` treats references to undefined variables as errors instead of silently using an empty string. `set -o pipefail` makes a pipeline fail if any command in the pipe fails, not just the last one. Together they prevent scripts from silently continuing after a failure.

Why do bash scripts need a boilerplate?

Without proper error handling, a bash script will keep running after a failure and leave your system in a broken or partial state. A boilerplate enforces safe defaults upfront so you only need to write the logic for your actual task, not the error handling scaffolding.

How do I add argument parsing to a bash script?

Use `getopts` for single-character flags like `-v` and `-f filename`. For long flags like `--verbose` or `--file`, use a `while` loop with a `case` statement on `$1` and `shift`. The generator outputs both patterns ready to customize.

Are the generated scripts safe to use in production?

Yes. The templates follow the same conventions used in production Linux scripts: `set -euo pipefail`, cleanup traps on EXIT, explicit non-zero exit codes on failure, and named variables instead of positional magic numbers. Review and test any generated script before running it in your environment.
