sed problem - replacement string should be same length as matching string.
Hi guys, I hope you can help me with my problem.
I have a text file that contains lines like this:
78 ANGELO -809.05
79 ANGELO2 -5,000.06
I need to find all occurences of amounts that are negative and replace them with x's
78 ANGELO xxxxxxx
79 ANGELO2 xxxxxxxxx
Note that the number of x's should match the number of characters replaced, that is, since -809.05 is 7 chars long, it should be replaced by 7x's. The x's should also be in the same position as where the original negative sign was to preserve the line spacing of the file.
Any idea how to do this? Thanks for your help.

xmlistreplaceitemsposunselected
XmListReplaceItemsPosUnselected(3X) XmListReplaceItemsPosUnselected(3X)
NAME
XmListReplaceItemsPosUnselected - A List function that replaces items in a list without selecting the replacement items
SYNOPSIS
#include <Xm/List.h>
void XmListReplaceItemsPosUnselected (widget, new_items, item_count, position)
Widget widget;
XmString *new_items;
int item_count;
int position;
DESCRIPTION
XmListReplaceItemsPosUnselected replaces the specified number of items in the list with new items, starting at the given position. The
replacement items remain unselected, even if they currently appear in the XmNselectedItems list. Specifies the ID of the List widget to
replace items in. Specifies a pointer to the replacement items. Specifies the number of elements in new_items and the number of items in
the list to replace. This number must be non-negative. Specifies the position of the first item in the list to be replaced. A value of 1
indicates that the first item replaced is the first item in the list; a value of 2 indicates that it is the second item; and so on.
Beginning with the item specified in position, item_count items in the list are replaced with the corresponding elements from
new_items. That is, the item at position is replaced with the first element of new_items; the item after position is replaced with
the second element of new_items; and so on, until item_count is reached.
For a complete definition of List and its associated resources, see XmList(3X).
