Here's my attempt.
I would avoid all those pipelines and try to do all transformations in awk or sed or Perl etc.

Code:

$
$ echo $LSB_MCPU_HOSTS
t70c7n120 16 t70c7n121 16 t70c7n122 16 t70c7n123 16 t70c7n124 16 t70c7n125 16 t70c7n126 16 t70c7n127 16 t70c7n128 16 t70c7n129 16 t70c7n130 16 t70c7n131 16 t70c7n132 16 t70c7n117 16 t70c7n118 16 t70c7n119 16
$
$ echo $LSB_MCPU_HOSTS | awk '{ $2 = "15";
                                for(i=1; i<=NF; i+=2) {
                                    n = i+1;
                                    print $n, $i;
                                    if (i == 1){print "cp", $1}
                                }
                              }'
15 t70c7n120
cp t70c7n120
16 t70c7n121
16 t70c7n122
16 t70c7n123
16 t70c7n124
16 t70c7n125
16 t70c7n126
16 t70c7n127
16 t70c7n128
16 t70c7n129
16 t70c7n130
16 t70c7n131

feed2imap-cleaner(1)					      General Commands Manual					      feed2imap-cleaner(1)

NAME

       feed2imap-cleaner - Removes old items from IMAP folders

SYNOPSIS

       feed2imap-cleaner [OPTIONS]

DESCRIPTION

       feed2imap-cleaner  deletes  old	items  from  IMAP  folders  specified in the configuration file. The actual query string used to determine
       whether an item is old is : "SEEN NOT FLAGGED BEFORE (3 days ago)". Which means that an item WON'T be deleted if it satisfies  one  of  the
       following conditions :

       o It isn't 3 days old ;

       o It hasn't been read yet ;

       o It is flagged (marked as Important, for example).

       -d, --dry-run
	 Don't remove anything, but show what would be removed if run without this option.

       -f, --config file
	 Use another config file (~/.feed2imaprc is the default).

BUGS

       Deletion criterias should probably be more configurable.
