removing certain tabs
I have a tab delimited file with many lines, one for each record.
each line is tab delimited with a tab before the first data field, a tab between each data field, and a tab after the last data field before it moves onto the next line.
I need to remove only the preceeding tab before the first data field and the tab after the last data field.
I'm sure this can be done with sed, but I don't really know the command that well.
Can anyone help?

If I have a crontab that looks like this

What does the 6 mean ? if the * means that everyday it should run then why would the 6th day be signified ? Shouldn't it be a * also?

xmprocesstraversal
XmProcessTraversal(3X) XmProcessTraversal(3X)
NAME
XmProcessTraversal - A function that determines which component receives keyboard events when a widget has the focus
SYNOPSIS
#include <Xm/Xm.h>
Boolean XmProcessTraversal (widget, direction)
Widget widget;
XmTraversalDirection direction;
DESCRIPTION
XmProcessTraversal determines which component of a hierarchy receives keyboard events when the hierarchy that contains the given widget has
keyboard focus. Using XmProcessTraversal to traverse to MenuBars, Pulldown MenuPanes, or Popup MenuPanes is not supported. Specifies the
widget ID of the widget whose hierarchy is to be traversed. The hierarchy is only traversed up to the top of the shell. If that shell does
not currently have the focus, any changes to the element with focus within that shell will not occur until the next time the shell receives
focus. Specifies the direction of traversal
The direction parameter can have the following values, which cause the routine to take the corresponding actions: XmTRAVERSE_CURRENT--Finds
the hierarchy and the tab group that contain widget. If this tab group is not the active tab group, makes it the active tab group. If wid-
get is an item in the active tab group, makes it the active item. If widget is the active tab group, makes the first traversable item in
the tab group the active item. XmTRAVERSE_DOWN--Finds the hierarchy that contains widget. Finds the active item in the active tab group
and makes the item below it the active item. If there is no item below, wraps. XmTRAVERSE_HOME--Finds the hierarchy that contains widget.
Finds the active item in the active tab group and makes the first traversable item in the tab group the active item. XmTRA-
VERSE_LEFT--Finds the hierarchy that contains widget. Finds the active item in the active tab group and makes the item to the left the
active item. If there is no item to the left, wraps. XmTRAVERSE_NEXT--Finds the hierarchy that contains widget. Finds the active item in
the active tab group and makes the next item in child order the active item. XmTRAVERSE_NEXT_TAB_GROUP--Finds the hierarchy that contains
widget. Finds the active tab group (if any) and makes the next tab group the active tab group in the hierarchy. XmTRAVERSE_PREV--Finds the
hierarchy that contains widget. Finds the active item in the active tab group and makes the previous item in child order the active item.
XmTRAVERSE_PREV_TAB_GROUP--Finds the hierarchy that contains widget. Finds the active tab group (if any) and makes the previous tab group
the active tab group in the hierarchy. XmTRAVERSE_RIGHT--Finds the hierarchy that contains widget. Finds the active item in the active tab
group and makes the item to the right the active item. If there is no item to the right, wraps. XmTRAVERSE_UP--Finds the hierarchy that
contains widget. Finds the active item in the active tab group and makes the item above it the active item. If there is no item above,
wraps.
CAUTIONS
XmProcessTraversal will not allow traversal to a widget in a different shell. XmProcessTraversal will only allow traversal to widgets that
are currently mapped. You cannot call XmProcessTraversal from inside a focusCallback routine (or you will get a segmentation fault).
RETURN VALUE
Returns True if the setting succeeded. Returns False if the keyboard focus policy is not XmEXPLICIT, if there are no traversable items, or
if the call to the routine has invalid parameters.
