This is straight forward and should work in both Kshell and bash. After the loop executes two arrays (indexed 0 to n-1) will exist:

Code:
i=0
sed 's/.*=//; s/,/ /' your-file  >/tmp/tfile.$$
while read a b
do
    names[$i]="$a"
    locs[$i]="$b"
    (( i++ ))
done </tmp/tfile.$$
rm /tmp/tfile.$$


The code above can be done in Kshell without using a tmp file; pipe the output from the sed directly into the while. Unfortunately that won't work in bash which is why I presented it the way I did.

This code below is more cryptic, but doesn't require the use of a tmp file to work in bash:
Code:
eval $(awk -F "[=,]" '
    {
        names = names " " $2;
        locs = locs " " $3;
    }
    END { printf( "names=( %s ); locs=( %s )", names, locs ); }
' your-input-file )

CPANPLUS::Shell(3perl)					 Perl Programmers Reference Guide				    CPANPLUS::Shell(3perl)

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 $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.
