Ubuntu 10.10 MySQL无法安装

一直到安装完都还算好，运行终端
oracle@zlc-laptop:/$ export ORACLE_SID=orcl
oracle@zlc-laptop:/$ $ORACLE_HOME/bin/sqlplus '/as sysdba'

就这样出错了，不知道是什么原因，请大家帮我找找原因吧

我记得在安装oracle中运行/u01/app/oracle/product/11.2.0/dbhome_1/root.sh出了一个错误
root@zlc-laptop:/# /u01/app/oracle/product/11.2.0/dbhome_1/root.sh
/u01/app/oracle/product/11.2.0/dbhome_1/root.sh: line 50: 在未预料的“set”附近出现语法错误
/u01/app/oracle/product/11.2.0/dbhome_1/root.sh: line 50: ` if ("$READ" != '') set ORASID="$READ"'
会不会和这个有关，求解决方案。
