Welcome to the forum.
You have done a good job of writing the script as a learner.
There are some points you could make a note of.
1) repetitive execution of the same commands should be avoided.
2) redundant code should be avoided.
3) printLogoffs and printLogons functions seems to be no use in your case. those are just printing the difference of the files which you already stored.
4) wc would print newlines, words, and bytes for the files. In your case you are taking words (lines should be more safer I guess)
5) print on screen and redirecting to the file both can be achieved on one command with tee. look for it.

For printing just the differences ( logon and logoff functions) you could just cat the files. Ditto for logon.

By 12pm daily, our system is expecting all input files to be uploaded by the script.

Lets say I wanted to create a script that would show what people are doing on my machine using the w command and refresh in about 6 seconds. What would be the easiest way to do this? I pretty much want the script to loop until I stop it.
I'm using the BASH shell by the way.
Help is appreciated.... (1 Reply)

Hello,
This is basic (i think). I am trying to run a shell script which would go into each folder (folder names defined in the list) and after entering would run some commands, once done, come out of the folder and continue until the list ends.

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.
