What you get when you open Shell Terminal.
Interactive REPL
Type commands and press Enter — no separate Run needed
Virtual filesystem
Pipes and paths against mounted sample/local files
Data panel
Upload CSVs and inspect them from the shell
AI + packages

# sales.csv loads automatically from the Data panel
head -5 sales.csv
echo "--- West region ---"
grep West sales.csv
echo "--- Total revenue ---"
awk -F, 'NR>1 { sum += $3 } END { print "Total:", sum }' sales.csv
echo "--- Top regions ---"
tail -n +2 sales.csv | sort -t, -k3 -nr | head -3
