| idle [-dns] [-t title] (-c cmd | -r file) [arg]* |
| idle [-dns] [-t title] - [arg]* |
| |
| -h print this help message and exit |
| -n run IDLE without a subprocess (see Help/IDLE Help for details) |
| |
| The following options will override the IDLE 'settings' configuration: |
| |
| -e open an edit window |
| -i open a shell window |
| |
| The following options imply -i and will open a shell: |
| |
| -c cmd run the command in a shell, or |
| -r file run script from file |
| |
| -d enable the debugger |
| -s run $IDLESTARTUP or $PYTHONSTARTUP before anything else |
| -t title set title of shell window |
| |
| A default edit window will be bypassed when -c, -r, or - are used. |
| |
| [arg]* are passed to the command (-c) or script (-r) in sys.argv[1:]. |
| |
| Examples: |
| |
| idle |
| Open an edit window or shell depending on IDLE's configuration. |
| |
| idle foo.py foobar.py |
| Edit the files, also open a shell if configured to start with shell. |
| |
| idle -est "Baz" foo.py |
| Run $IDLESTARTUP or $PYTHONSTARTUP, edit foo.py, and open a shell |
| window with the title "Baz". |
| |
| idle -c "import sys; print(sys.argv)" "foo" |
| Open a shell window and run the command, passing "-c" in sys.argv[0] |
| and "foo" in sys.argv[1]. |
| |
| idle -d -s -r foo.py "Hello World" |
| Open a shell window, run a startup script, enable the debugger, and |
| run foo.py, passing "foo.py" in sys.argv[0] and "Hello World" in |
| sys.argv[1]. |
| |
| echo "import sys; print(sys.argv)" | idle - "foobar" |
| Open a shell window, run the script piped in, passing '' in sys.argv[0] |
