see below this might help

Code:
ok.. this is an excerpt from man ksh
           ${parameter#pattern}
           ${parameter##pattern}
                               If the shell pattern matches the beginning of
                               the value of parameter, the value of this
                               substitution is the value of the parameter
                               with the matched portion deleted; otherwise
                               the value of this parameter substituted.  In
                               the former case, the smallest matching
                               pattern is deleted; in the latter case, the
                               largest matching pattern is deleted


basically FILE_LOC is a location and d is also a location and if ur pattern of location matches with each other. then only the portion (directory in the last that is not being matched is shown)

EvmEventNameMatch(3)					     Library Functions Manual					      EvmEventNameMatch(3)

NAME
EvmEventNameMatch, EvmEventNameMatchStr - Match event name LIBRARY
EVM Support Library (libevm.so, libevm.a) SYNOPSIS
#include <evm/evm.h> EvmStatus_t EvmEventNameMatch( const char *pattern, EvmEvent_t event, EvmBoolean_t *match); EvmStatus_t EvmEventNameMatchStr( const char *pattern, const char *candidate, EvmBoolean_t *match); OPERANDS
The event name pattern sought. The pattern may be any valid event name string. It may include wildcard characters in place of any compo- nent. The event containing the event name to be compared against the pattern. The result of the match. This parameter is set to EvmTRUE if the name matches the pattern, and to EvmFALSE if it does not. A character string to be matched against the pattern DESCRIPTION
Because special matching rules apply when deciding whether a candidate event name matches a known name, the EVM name matching functions should be used for matching purposes, rather than the C string comparison functions (memcpm(), strcmp()) . The EVM functions match an event name against a supplied pattern, ignoring any trailing appended components in the candidate name, and correctly matching wildcard characters. The EvmEventNameMatch function takes an event and an event name pattern as input, and returns an indication of whether the event contains a name which matches the pattern in the match output argument. The pattern may be any valid event name string, and may also include wildcard characters in place of any component. A wildcard * in the pattern matches zero or more name components. A ? matches exactly one compo- nent. A match occurs if the event name matches all components indicated by the pattern, even if the name has additional trailing elements. The EvmEventNameMatchStr function performs the same check as EvmEventNameMatch, but takes a character string as the candidate event name, rather than extracting it from a supplied event. Both functions set the match output argument to EvmTRUE if the name matches the pattern, and to EvmFALSE if it does not. RETURN VALUES
The comparison was successful. The value of the match parameter indicates whether the name matches the pattern. The supplied pattern con- tains invalid characters. The supplied event does not contain a name. ERRORS
