my file looks like this:
101928 101943
101928 101944
101929 101943
101929 101943
101929 102044
i want to insert bc to get answer like this:
101928 101943 000015
101928 101944 000016
101929 101943 000013
101929 101943 000014
101929 102044 000115
total 000173
my way:
create two files (col2.txt and col2.txt)
cat col2.txt | while read col2
do
cat col1.txt | while read col1
do
echo $col2 - $col1 | bc > total.txt
done
done
must be a short version of it.

Gtk2::ListStore(3pm) User Contributed Perl Documentation Gtk2::ListStore(3pm)
NAME
Gtk2::ListStore - wrapper for GtkListStore
HIERARCHY
Glib::Object
+----Gtk2::ListStore
INTERFACES
Gtk2::TreeModel
Gtk2::TreeDragSource
Gtk2::TreeDragDest
Gtk2::TreeSortable
Gtk2::Buildable
METHODS
liststore = Gtk2::ListStore->new (...)
o ... (list) of strings
treeiter = $list_store->append
$list_store->clear
$list_store->set_column_types (...)
o ... (list) of strings
$list_store->set ($iter, $col1, $val1, ...)
o $iter (Gtk2::TreeIter)
o $col1 (integer) the first column number
o $val1 (scalar) the first value
o ... (list) pairs of column numbers and values
treeiter = $list_store->insert ($position)
o $position (integer)
treeiter = $list_store->insert_after ($sibling)
o $sibling (Gtk2::TreeIter or undef)
treeiter = $list_store->insert_before ($sibling)
o $sibling (Gtk2::TreeIter or undef)
treeiter = $list_store->insert_with_values ($position, ...)
o $position (integer) position to insert the new row
o ... (list) pairs of column numbers and values
Like doing insert followed by set, except that insert_with_values emits only the row-inserted signal, rather than row-inserted, row-
changed, and, if the store is sorted, rows-reordered as in the multiple-operation case. Since emitting the rows-reordered signal
repeatedly can affect the performance of the program, insert_with_values should generally be preferred when inserting rows in a sorted list
store.
Since: gtk+ 2.6
boolean = $list_store->iter_is_valid ($iter)
o $iter (Gtk2::TreeIter)
Since: gtk+ 2.2
$store->move_after ($iter, $position)
o $iter (Gtk2::TreeIter)
o $position (Gtk2::TreeIter or undef)
Since: gtk+ 2.2
$store->move_before ($iter, $position)
o $iter (Gtk2::TreeIter)
o $position (Gtk2::TreeIter or undef)
Since: gtk+ 2.2
treeiter = $list_store->prepend
boolean = $list_store->remove ($iter)
o $iter (Gtk2::TreeIter)
The return is always a boolean in the style of Gtk 2.2.x and up, even when running on Gtk 2.0.x.
$store->reorder (...)
o ... (list) of integers the reordered posistions
Reorders store to follow the order indicated by new_order. Note that this function only works with unsorted stores.
A list of position should be passed, one for each item in the list.
Since: gtk+ 2.2
$store->swap ($a, $b)
o $a (Gtk2::TreeIter)
o $b (Gtk2::TreeIter)
Since: gtk+ 2.2
$list_store->set_value ($iter, $col, $val)
o $iter (Gtk2::TreeIter)
o $val (scalar)
o $col (integer)
