Running post GIS script

Dear All, I am very new to postGIS. I have installed the postGIS and dcmms database on windows. I have loaded one shape file into the database. I have a script to be run on that database but i am not able to run it. Can some one please help me on how to do it. I have pasted that script here below. if test $# -lt 4 then echo "Usage: $0 dbname plss_shapefile inpath outpath " echo 'Where dbname=name of the PostGIS database' echo 'plss_shapefile = name of the PLSS shapefile' echo 'inpath = the path where the shapefile resides' echo 'outpath = the path where your quad plss should reside' else echo "drop table plss;"|psql -d $1 echo "delete from geometry_columns where f_table_name='plss';"|psql -d $1 echo "drop table plss_quad;"|psql -d $1 echo "delete from geometry_columns where f_table_name='plss_quad';"|psql -d $1 cd $3 # Import the parcel shapefile into PostGIS database and in AEA projection ogr2ogr -f "PostgreSQL" PG:dbname=$1 $2 -nln plss -lco 'PRECISION=NO' -lco 'OVERWRITE=YES' -nlt GEOMETRY # Build an index echo 'Create Index plss_index on plss using gist (wkb_geometry GIST_GEOMETRY_OPS);'|psql -d $1 # Vacuum Analyze echo 'vacuum analyze plss;'|psql -d $1 # add column quadrant to the table echo 'alter table plss add column region varchar(40);'|psql -d $1 echo "update plss set region='Northeast' where sec in (1,2,3,10,11,12,13,14,15);"|psql -d $1 echo "update plss set region='Northwest' where sec in (4,5,6,7,8,9,16,17,18);"|psql -d $1 echo "update plss set region='Southeast' where sec in (22,23,24,25,26,27,34,35,36);"|psql -d $1 echo "update plss set region='Southwest' where sec in (19,20,21,28,29,30,31,32,33);"|psql -d $1 echo "alter table plss add column quadrant varchar(50);"|psql -d $1 echo "update plss set quadrant='TWP.
