Top Forums UNIX for Dummies Questions & Answers How to make each login shell history independent for same account? Post 302939787 by Don Cragun on Sunday 29th of March 2015 01:36:04 AM

I didn't say to look at the HISTORY man page; I said to look at the man page for your shell (ksh in this case) and look for the HIStORY environment variable on that man page.

If you're users are logging in to an environment running csh and they manually invoke ksh, the simple thing to do is something like the following while you are still in csh:
Code:
setenv HISTFILE=$HOME/.ksh_history.username
exec ksh

where username is the real name of the user logging in to this shared environment; not the shared account name everyone is logging into on this machine. That will give each user a separate history file (and keep track of the commands that user has used across logins).

NAME
isympy - interactive shell for SymPy SYNOPSIS
isympy [-c | --console] isympy [ {-h | --help} | {-v | --version} ] DESCRIPTION
isympy is a Python shell for SymPy. It is just a normal python shell (ipython shell if you have the ipython package installed) that exe- cutes the following commands so that you don't have to: >>> from __future__ import division >>> from sympy import * >>> x, y, z = symbols("xyz") >>> k, m, n = symbols("kmn", integer=True) So starting isympy is equivalent to starting python (or ipython) and executing the above commands by hand. It is intended for easy and quick experimentation with SymPy. For more complicated programs, it is recommended to write a script and import things explicitly (using the "from sympy import sin, log, Symbol, ..." idiom). OPTIONS
-c shell, --console=shell Use the specified shell (python or ipython) as console backend instead of the default one (ipython if present or python otherwise). Example: isympy -c python FILES
${HOME}/.sympy-history Saves the history of commands when using the python shell as backend. BUGS
The upstreams BTS can be found at <http://code.google.com/p/sympy/issues/list> Please report all bugs that you find in there, this will help improve the overall quality of SymPy. SEE ALSO
