Script for extracting data from csv file based on column values.

Hi all,

I am new to shell script.I need your help to write a shell script.
I need to write a shell script to extract data from a .csv file where columns are ',' separated.
The file has 5 columns having values say column 1,column 2.....column 5 as below along with their valuesm.
ref_num,Account Number,Misc, error 1,error 2

Code:

COD  , 121, misc, 0, 0
COD1, 123, misc2,1, 1

Now i want to write a script to first check if the file name.csv exists at /home/home1.
If the file exists i want to display column 1 to column 5 header along with their values only if the column error 1 or error 2 column has any other value than 0 i.e it should not have 0.

Output for above input should be like below:

Code:

ref_num:COD1
Account Number:123
Misc:misc2
error 1:1
error 2:1

colrm

COLRM(1)						    BSD General Commands Manual 						  COLRM(1)

NAME

     colrm -- remove columns from a file

SYNOPSIS

     colrm [start [stop]]

DESCRIPTION

     The colrm utility removes selected columns from the lines of a file.  A column is defined as a single character in a line.  Input is read
     from the standard input.  Output is written to the standard output.

     If only the start column is specified, columns numbered less than the start column will be written.  If both start and stop columns are spec-
     ified, columns numbered less than the start column or greater than the stop column will be written.  Column numbering starts with one, not
     zero.

     Tab characters increment the column count to the next multiple of eight.  Backspace characters decrement the column count by one.

ENVIRONMENT

     The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of colrm as described in environ(7).

EXIT STATUS

     The colrm utility exits 0 on success, and >0 if an error occurs.

SEE ALSO

     awk(1), column(1), cut(1), paste(1)

HISTORY

     The colrm command appeared in 3.0BSD.
