How to replace anything before a pattern?

Hi,
I have the following text file:

Code:

facdat=$SPDR_SHARED_SCRIPTS/mdb_facdat.pl -s fnma;
upddte=$AGENCY_SCRIPTS/get_upddte.pl -f $EMBS_DAILY_DIR/$filenm
$SASRUN $AGENCY_SCRIPTS/fnma_daily_factors.sas -sysparm "$facdat $upddte"
$SASRUN $AGENCY_SCRIPTS/fnma_daily_addtn.sas -sysparm "$facdat $upddte"
repret=$SPDR_SHARED_SCRIPTS/mdb_facdat.pl -s $sectyp -r Y

I want to replace anything before '$AGENCY_SCRIPTS' and '$SPDR_SHARED_SCRIPTS' I want my output to look like below

Code:

$SPDR_SHARED_SCRIPTS/mdb_facdat.pl -s fnma;
$AGENCY_SCRIPTS/get_upddte.pl -f $EMBS_DAILY_DIR/$filenm
$AGENCY_SCRIPTS/fnma_daily_factors.sas -sysparm "$facdat $upddte"
$AGENCY_SCRIPTS/fnma_daily_addtn.sas -sysparm "$facdat $upddte"
$SPDR_SHARED_SCRIPTS/mdb_facdat.pl -s $sectyp -r Y

The t saves/prevents looking for B if you find A. While this list is trivial, longer lists can be created with the most likely at the top to save processing, when you do many possible transforms.
