Example pysh.py not functioning properly

[GoogleCodeExporter]

The pysh.py does not work well for me unless I change data types to string. As 
is, the code currently gives the following output after a caput command.

caput MTEST:COMMAND 'whoami'

caget command gives similar results. After changing the Command and Output 
types to string the program behaves as expected. 

I'm not sure why my system behaves this way. Ive tried Python 2.7 and 3.2. I'm 
using Linux Mint linux-x86_64 and EPICS base 3.14.12.1

Sorry for the late reply since googlecode didn't notice me.

This is because COMMAND and OUTPUT has been changed from 'string' to 'char' 
type. And I forgot to change the Wiki document. By 'char' type, one needs to 
pass the '-S' switch to treat char array as string.
{{{
caput -S MTEST:COMMAND 'whoami'
caget -S MTEST:OUTPUT
}}}
I have corrected the Wiki page.
