Scripting questions

[Abdussamad Abdurrazzaq <abdussamad hotpop com>]

Hello

Please help me with these basic scripting questions. How do you tell the path 
of the current directory? Is there an equivalent to the Left$ & Right$ 
functions found in BASIC in Linux scripting? What I mean is how do you 
extract a given number of characters from the left or right of a string?

TIA
