Thanks
Hi Pamu/All,
Your code works perfectly.
I am sorry for little confusion here.
My actual input data looks like this
Code:
Type,Data1,Data2,Data3 
A,2,3,4 
B,3,4,SOME STRING 
C,4,Inf,5 
D,5,4,4

Where column header Type is a string which says case of each row. Some times there will be many like Type1,Type2 etc columns and I want to preserve them
and make your code work on the rest of the columns like 4 to last column.
Basically I want to offset column number from where I need to remove columns that have strings.

If possible modify your code to account for my request.

Thanks
Sidda

column

COLUMN(1)						    BSD General Commands Manual 						 COLUMN(1)

NAME

     column -- columnate lists

SYNOPSIS

     column [-tx] [-c columns] [-s sep] [file ...]

DESCRIPTION

     The column utility formats its input into multiple columns.  Rows are filled before columns.  Input is taken from file operands, or, by
     default, from the standard input.	Empty lines are ignored.

     The options are as follows:

     -c      Output is formatted for a display columns wide.

     -s      Specify a set of characters to be used to delimit columns for the -t option.

     -t      Determine the number of columns the input contains and create a table.  Columns are delimited with whitespace, by default, or with
	     the characters supplied using the -s option.  Useful for pretty-printing displays.

     -x      Fill columns before filling rows.

DIAGNOSTICS

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

ENVIRONMENT

     COLUMNS  The environment variable COLUMNS is used to determine the size of the screen if no other information is available.

EXAMPLES

	   (printf "PERM LINKS OWNER GROUP SIZE MONTH DAY " ; 
	   printf "HH:MM/YEAR NAME
" ; 
	   ls -l | sed 1d) | column -t

SEE ALSO

     colrm(1), ls(1), paste(1), sort(1)

HISTORY

     The column command appeared in 4.3BSD-Reno.
