## CLI Commands
Place scripts in a folder. After writing, run:
- `wmill script generate-metadata` - Generate .script.yaml and .lock files
- `wmill sync push` - Deploy to Windmill
Use `wmill resource-type list --schema` to discover available resource types.
# Bash
## Structure
Do not include `#!/bin/bash`. Arguments are obtained as positional parameters:
```bash
# Get arguments
var1="$1"
var2="$2"
echo "Processing $var1 and $var2"
# Return JSON by echoing to stdout
echo "{\"result\": \"$var1\", \"count\": $var2}"
```
**Important:**
- Do not include shebang (`#!/bin/bash`)
- Arguments are always strings
- Access with `$1`, `$2`, etc.
## Output
The script output is captured as the result. For structured data, output valid JSON:
```bash
name="$1"
count="$2"
# Output JSON result
cat << EOF
{
"name": "$name",
"count": $count,
"timestamp": "$(date -Iseconds)"
}
EOF
```
## Environment Variables
Environment variables set in Windmill are available:
```bash
# Access environment variable
echo "Workspace: $WM_WORKSPACE"
echo "Job ID: $WM_JOB_ID"
```
