${parameter#word}
${parameter##word}
The word is expanded to produce a pattern just as in pathname
expansion. If the pattern matches the beginning of the value of
parameter, then the result of the expansion is the expanded
value of parameter with the shortest matching pattern (the ``#''
case) or the longest matching pattern (the ``##'' case) deleted.
If parameter is @ or *, the pattern removal operation is applied
to each positional parameter in turn, and the expansion is the
resultant list. If parameter is an array variable subscripted
with @ or *, the pattern removal operation is applied to each
member of the array in turn, and the expansion is the resultant
list.
${parameter%word}
${parameter%%word}
The word is expanded to produce a pattern just as in pathname
expansion. If the pattern matches a trailing portion of the
expanded value of parameter, then the result of the expansion is
the expanded value of parameter with the shortest matching pat-
tern (the ``%'' case) or the longest matching pattern (the
``%%'' case) deleted. If parameter is @ or *, the pattern
removal operation is applied to each positional parameter in
turn, and the expansion is the resultant list. If parameter is
an array variable subscripted with @ or *, the pattern removal
operation is applied to each member of the array in turn, and
the expansion is the resultant list.
I have a file (status.file) of the form:

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.
