Hi,
I am using python -i, and I find it hard typing/pasting the commands
from the previous interactive shell. Basically, is there anyway that I
can preserve the history in the shell?
I guess but not sure there should be something like ~/.pyrc for
configuring such but can someone please let me know what is the
effective environment variable to preserve the history?
Thanks,
Nikhil
I figured it out. This below thing works fine for me.
BTW, I got it from http://docs.python.org/tut/node15.html. A little
search would not hurt ;-)
$ echo $PYTHONSTARTUP
/u/me/.pyrc
$ cat .pyrc
import sys
import atexit
import os
import readline
import rlcompleter
myprompt='$ '
myhistoryfile="/u/me/.pyhistory"
#set the prompt
sys.ps1=myprompt
#save the history
historyPath = os.path.expanduser(myhistoryfile)
def save_history(historyPath=historyPath):
import readline
readline.write_history_file(historyPath)
if os.path.exists(historyPath):
readline.read_history_file(historyPath)
atexit.register(save_history)
del os, atexit, readline, rlcompleter, save_history, historyPath
