Shell Script Development

Create shell scripts following consistent conventions.

Template

#!/usr/bin/env bash

set -e -o pipefail

# Colors
green='\033[0;32m'
red='\033[0;31m'
yellow='\033[1;33m'
blue='\033[0;34m'
nc='\033[0m'

# Script logic here

echo -e "${green}✔${nc} completed successfully"

Conventions

Element	Convention
Shebang	`#!/usr/bin/env bash`
Safety	`set -e -o pipefail`
Local variables	Lowercase (`model`, `dir`, `count`)
Environment variables	Uppercase (`PATH`, `HOME`, `USER`)
Color variables	Lowercase (`green`, `red`, `nc`)
Status words	Lowercase (`error`, `warning`, `note`)

Status Output Patterns

echo -e "${green}✔${nc} task completed"           # success
echo -e "${red}error${nc}: something failed"      # error
echo -e "${yellow}warning${nc}: something to note" # warning
echo -e "${blue}info${nc}: informational message"  # info

Important

After creating or modifying shell scripts, inform the user:

Make executable. Run chmod +x script.sh before use.
