쉘 스크립트 - 루프에서 변수 사용

Question

다음의 명령을 grant postgres db에 사용합니다. 그것은 효과가있다.

for tbl in `psql -qAt -c "select sequence_name from information_schema.sequences where sequence_schema = 'public';" performanceeyedev` ; do psql -c "alter table $tbl owner to prodteam" performanceeyedev ; done 

다음 게시물은 grant postgres db에 쓰여 있습니다. 하지만 작동하지 않습니다.

DB = 'performanceeyedev'; 
OWNER = 'prodteam'; 

for tbl in `psql -qAt -c "select sequence_name from information_schema.sequences where sequence_schema = 'public';" $DB` ; 
do psql -c "alter table $tbl owner to $OWNER" $DB ; done 

for tbl in `psql -qAt -c "select table_name from information_schema.views where table_schema = 'public';" $DB` ; 
do psql -c "alter seq $tbl owner to $OWNER" $DB ; done
