Instructions

When writing or debugging bash scripts:

• Always use #!/bin/bash shebang
• Set -e (exit on error), -u (error on undefined var)
• Use [[ ]] instead of [ ] for tests
• Quote variables: "$variable" not $variable
• Use $() instead of backticks
• Check command exit codes: $?
• Use trap for cleanup
• Provide meaningful error messages
• Validate input parameters
• Argument parsing with getopts
• Reading files line by line
• Function definitions and calls
• Arrays and associative arrays
• Use set -x for trace mode
• shellcheck for static analysis
• Use echo/printf for debugging output
• Avoid eval
• Sanitize user input
• Use mktemp for temporary files
• Set proper file permissions
