Just check the field number in the for lop and print out the lines you want.
I removed 1 and now i want to check for leading and trailing space or tab on each field.
The below code returns nothing.
Code:
nawk -F"|" '{for(i=1;i<=NF;i++) {if ($i ~ "^[ \t]+" || $i ~ "[ \t]+$")}}' file

Help appreciated

NAME
XmTabListRemoveTabs -- A convenience function that removes noncontiguous tabs SYNOPSIS
#include <Xm/Xm.h> XmTabList XmTabListRemoveTabs( XmTabList oldlist, Cardinal *position_list, Cardinal position_count); DESCRIPTION
XmTabListRemoveTabs removes noncontiguous tabs from a tab list. The function creates a new tab list by copying the contents of oldlist and removing all tabs whose corresponding positions appear in the position_list array. A warning message is displayed if a specified position is invalid; for example, if the value is a number greater than the number of tabs in the tab list. tablist Specifies the tab list. The function deallocates oldlist and the tabs it contains after extracting the required information. position_list Specifies an array of the tab positions to be removed. The position of the first tab in the list is 0 (zero), the position of the second tab is 1, and so on. position_count Specifies the number of elements in the position_list. RETURN
If oldlist or position_list is NULL, or position_count is 0 (zero), returns oldlist. Otherwise, this function returns the new tab list. The function allocates space to hold the returned tab list. The application is responsible for managing the allocated space. The applica- tion can recover the allocated space by calling XmTabListFree. RELATED
