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.shbefore use.
