counter=0

for p in $pid
do
c=${ch[$counter]}
echo "$c ..$counter"
counter=$((counter+1))
done

The filed 10 has 3 values: 14,19,6 in tmp.txt file. When I execute, I am getting:

14
19
6 ..0
..1
..2

but I would like to have:

14 ..0
19 ..1
6 ..2

Could you please help me to fix this?

Thanks in advance,
Ezhil
Code:
# cat justdoit
#!/bin/bash
ch=($(cut -d" " -f10 tmp.txt|tr -s "," " "))
counter=0
for((i=0;i<=${#ch};i++)); do
c=${ch[$counter]}
echo "$c ..$counter"
((counter++))
done

Code:
# ./justdoit
14 ..0
19 ..1
6 ..2

CPANPLUS::Shell(3)					User Contributed Perl Documentation					CPANPLUS::Shell(3)

NAME

       CPANPLUS::Shell - base class for CPANPLUS shells

SYNOPSIS

	   use CPANPLUS::Shell; 	    # load the shell indicated by your
					    # config -- defaults to
					    # CPANPLUS::Shell::Default

	   use CPANPLUS::Shell qw[Classic]  # load CPANPLUS::Shell::Classic;

	   my $ui      = CPANPLUS::Shell->new();
	   my $name    = $ui->which;	    # Find out what shell you loaded

	   $ui->shell;			    # run the ui shell

DESCRIPTION

       This module is the generic loading (and base class) for all "CPANPLUS" shells. Through this module you can load any installed "CPANPLUS"
       shell.

       Just about all the functionality is provided by the shell that you have loaded, and not by this class (which merely functions as a generic
       loading class), so please consult the documentation of your shell of choice.

       Please report bugs or other issues to <bug-cpanplus@rt.cpan.org<gt>.
