In shells like the interactive python shell, you can usually use the arrow keys to move around in the current line or get previous commands (with arrow-up) etc.
But after I ssh into another machine and start
python there, I get sessions like:
>>> import os >>> ^[[A
where the last character comes from arrow-up. Or, using arrow-left:
How can I fix this?
In the regular bash, arrow keys work fine. The weird behavior is just in the interactive python (or perl etc.) shell.
Now we will see solution for issue: Seeing escape characters when pressing the arrow keys in python shell
Looks like readline is not enabled. Check if
PYTHONSTARTUP variable is defined, for me it points to
/etc/pythonstart and that file is executed by the python process before going interactive, which setups readline/history handling.
Thanks to @chown here is the docs on this: http://docs.python.org/2/tutorial/interactive.html
