If you do not want to install sqlplus on your server machine then the following command-line tool can be your friend  It is a simple Java application  only Java 8 that you need in order to you can execute this tool  The tool can be used to run any SQL from the Linux bash or Windows command line  Example  java -jar sql-runner-0 2 0-with-dependencies jar        -j jdbc oracle thin    oracle-db 1521 ORCLPDB1 localdomain        -U  quot SYS as SYSDBA quot         -P Oradoc db1          quot select 1 from dual quot   Documentation is here  You can download the binary file from here

I ve used the jdbcsql project on Sourceforge   On  nix systems  this will create a csv stream of results to standard out   java -Djava security egd file   dev urandom -jar jdbcsql jar -d oracledb SID -h  host -p 1521 -U some username -m oracle -P   PW  -f excel -s       1    Note that adding the -Djava security egd file   dev urandom increases performance greatly  Windows commands are similar  see http   jdbcsql sourceforge net

I m slightly confused   You should be able to call sqlplus from within the bash script   This may be what you were doing with your first statement  Try Executing the following within your bash script      bin bash           echo Start Executing SQL commands sqlplus  lt user gt   lt password gt   file-with-sql-1 sql sqlplus  lt user gt   lt password gt   file-with-sql-2 sql   If you want to be able to pass data into your scripts you can do it via SQLPlus by passing arguments into the script   Contents of file-with-sql-1 sql   select   from users where username   amp 1     Then change the bash script to call sqlplus passing in the value     bin bash  MY USER bob sqlplus  lt user gt   lt password gt   file-with-sql-1 sql  MY USER
