Re: Critic my module

Hi,

lets uses the ls example:
the way you do it now implies, that you search your PATH variable until 
it finds a
program called 'ls'. So if we are able to change the PATH variable, and 
put out own
'ls' somewhere in the (new) paths, calling you ls() will execute 
whatever we want our
own  ls' to do.

Second remark: if the behavior of some tools is changed (for examples 
with using aliases)
we cannot expect the called tool (in the example: 'ls') to give the same 
output on
every system.

this can be avoided (mostly) by ensuring that the right program (in the 
example /bin/ls) is called, and not only ls.

bg,
Johannes
