| 1245 | idle -est "Baz" foo.py |
| 1246 | Run $IDLESTARTUP or $PYTHONSTARTUP, edit foo.py, and open a shell |
| 1247 | window with the title "Baz". |
| 1248 | |
| 1249 | idle -c "import sys; print sys.argv" "foo" |

| 1251 | and "foo" in sys.argv[1]. |
| 1252 | |
| 1253 | idle -d -s -r foo.py "Hello World" |

| 1255 | run foo.py, passing "foo.py" in sys.argv[0] and "Hello World" in |
| 1256 | sys.argv[1]. |
| 1257 | |
