There was a problem initializing the tablespace

[imyouzhen]

I want to initialize a tablespace in the ‘entrypoint.sh’，added in line 84：
su oracle -c 'echo -e "create tablespace sino datafile '/u01/app/oracle/oradata/sino.dbf' size 1000M autoextend on next 100M maxsize unlimited;" | $ORACLE_HOME/bin/sqlplus -S / as sysdba'

Log output error information:
`create tablespace sino datafile /u01/app/oracle/oradata/sino.dbf size 1000M autoextend on next 100M maxsize unlimited
*
ERROR at line 1:
ORA-02236: invalid file name

`
I guess there's a problem with single quotes in the script。
So, what is the correct format?

init_test.zip

should be datafile '/u01/app/oracle/oradata/sino.dbf '
