Shell Programming and Scripting

hi all,
i have to read a file using shell script for example my csv file is
like this

Code:

Tid   Inputfille                  Inputfilepath
1    ABC_20141218.idr      /export/home/him60t1/input
2    ABC_20141219.idr     /export/home/him60t1/input1

what i have to do is if on my command line i type program.sh 1
then input file

Code:

ABC_20141218.idr

should be copied in filepath

Code:

/export/home/him60t1/input

and similarly if on my command line
i have 2 then the file on Tid 2 should be copied to corresponding
file path. and tid can go increasing

how should i read the csv.
can any one please help

what have you tried so far? To start with look for loops like for or while.. Once you get your head around those you can do this via awk as well..
