python - Installing pythonstartup file -

question: how install pythonstartup file runs on command? tried install /home directory ubuntu, said had insufficient permissions. furthermore, different places alternately should in caps or in lower case period before it. python command line guide not seem explain put file, or how change environment variable 'point' it.

thank in advance.

knowledge:

system: ubuntu

python experience: limited

ubuntu experience: more limited.

in ~/.bashrc:

export pythonstartup=$home/.pythonstartup 

and put python code in $home/.pythonstartup, like:

import rlcompleter import readline  readline.parse_and_bind("tab: complete") 

for more information pythonstartup variable, read python man page:

$ man python
