root@hadoop-senior hive-0.13.1]$ bin/hive -help

-d, --define <key=value> Variable subsitution to apply to hive
commands. e.g. -d A=B or --define A=B
--database <databasename> Specify the database to use
-e <quoted-query-string> SQL from command line
-f <filename> SQL from files
-H,--help Print help information
-h <hostname> connecting to Hive Server on remote host
--hiveconf <property=value> Use value for given property
--hivevar <key=value> Variable subsitution to apply to hive

-i <filename> Initialization SQL file
-p <port> connecting to Hive Server on port number
-S,--silent Silent mode in interactive shell

1.* bin/hive -e <quoted-query-string>
eg:
bin/hive -e "select * from db_hive.student ;"
2.* bin/hive -f <filename>
eg:
$ touch hivef.sql
select * from db_hive.student ;
$ bin/hive -f /opt/datas/hivef.sql
$ bin/hive -f /opt/datas/hivef.sql > /opt/datas/hivef-res.txt
3.* bin/hive -i <filename>
