NOHUP Command In Linux - oracle11g

I am issuing a command
$nohup sqlplus "/ as sysdba" #script.sql &
And on executing this nohup.out file contains this error:
Error 45 initializing SQL*Plus
How to resolve it?

Check the command terminators. If you have anonymous plsql blocks, typically they would look like
DECLARE
some stuff
BEGIN
sql statements;
END;
You have to add another line with a lone "/" after it, or you will get this error.

How can I quit sqlite from a command batch file?

I am trying to create a sealed command for my build pipeline which inserts data and quits.
So far I have created my data files
things-to-import-001.sql and 002 etc, which contains all the INSERT statements I'd like to run, with a file per table.
I have created a command file to run them
-- import-all.sql
.read ./things-to-import-001.sql
.read ./things-to-import-002.sql
.quit
However when I run my command
sqlite3 -init ./import-all.sql ./database.sqlite
..the data is inserted, but the program remains running and shows the sqlite> prompt, despite the .quit command. I have also tried using .exit 0.
From the sqlite3 --help
-init FILENAME read/process named file
Docs: https://www.sqlite.org/cli.html#reading_sql_from_a_file
How can I tell sqlite to exit once my inserts have finished?
I have managed to find a dirty workaround for this issue.
I have updated my import file to include a bad command, and executed using -bail to quit on first error.
-- import-all.sql
.read ./things-to-import-001.sql
.read ./things-to-import-002.sql
.fakeErrorToQuitWithBail
Then you can execute with
sqlite3 -init import-all.sql -bail
and it should quit with
Error: unknown command or invalid arguments: "fakeErrorToQuitWithBail". Enter ".help" for help
Try using ".exit" at the place of ".quit". For some reason SQLite dont doccumented this commands.

Why am I getting: database is locked, in an SQLite3 script?

I'm getting an error when running an SQLite script.
--drop use table before replacing it
DROP TABLE IF EXISTS db.use;
--Create the use table in the saved database
CREATE TABLE db.use AS SELECT * FROM use2; -- this is the line that generates the error: Error: near line 145: database is locked
Are these two statements run asynchronously or something? I don't understand what's causing the error, but I'm wondering if it has to do with that.
Might there be a way to run the script in a lock-step manner, i.e. non-asynchronously?
This is how I was running the command: sqlite3 --init script_name.sql dbname.db, and elsewhere in the script I had an ATTACH statement reading the same database dbname.db. Essentially reading the same file twice.
The way I solved this was by executing the script in the sqlite3 shell:
sqlite3> .read script_name.sql
Have you tried to add a commit statement after the drop statement?
I think that would make sure the create table statement run after the drop statement is totally done.

how to include new line in scipt log which is calling sql file and that sql file is giving lot of errors

I have written a shell script which is calling another sql file, which is disabling triggers in oracle.
but this sql file is generating lot of oracle errors and in log file of script, I am getting response like
ORA-21021 -- oracle errros ORA-20111 -- oracle errors
I would like to add a new line getting the oracle errors something like
ORA-21021 --** oracle errors**
ORA-20111 --** oracle errors**
How this can be done?
sql file code:
alter trigger trigger_name1 disable;
alter trigger trigger_name2 disable;
alter trigger trigger_name3 disable;
alter trigger trigger_name4 disable;
alter trigger trigger_name4 disable;
A solution with perl
perl -pe 's/ORA-\d/\n$&/g' <oldfile >newfile
to add a newline before sequences ORA- followed by a number (\d)
I was able to achieve this by below method:
SQL=$(echo "$SQL" | sed -e 's/ERROR/\\n\rERROR/g')
echo $SQL

Error while running a .sh script via QProcess

I have written a QT GUI program where pressing a button will execute a .sh script. The contents of the script is-
echo -e 'attach database 'testdatabase.db' as 'aj';\n.separator ","\n.import ora_exported.csv qt_ora_exported' | sqlite3 testdatabase.db
basically the script will import a .csv to an sqlite database. And when the script file (script.sh) is run manually from linux terminal ($./script.sh) it successfully imports the .csv file into the database table.
But, when I call the script from my QT program
void MainWindow::on_importButton_clicked()
{
QProcess process;
process.startDetached("/bin/sh",QStringList()<<"/home/aj/script.sh");
}
it compiles successfully but gives an error message in console when the button is pressed at runtime.
Error: near line 1: near "-": syntax error
Error: cannot open "ora_exported.csv"
what could be causing this ???
EDITED
I have changed my .sh script now to--
echo -e 'attach database 'testdatabase.db' as 'aj';\n.separator ","\n.import /home/aj/ora_exported.csv qt_ora_exported' | sqlite3 testdatabase.db
Thus providing the path to my ora_exported.csv. As a result the runtime error [Error: cannot open "ora_exported.csv"] has gone but the other message [Error: near line 1: near "-": syntax error] is still coming.
Same as was observed in previous case, using ./script.sh is successfully importing data to sqlite3 db table file but QProcess is unable to.
echo is a built in command of a shell that may behave differently.
E.g. take this test script: echotest.sh
echo -e "123"
Now we can compare different results:
$ bash echotest.sh
123
$ zsh echotest.sh
123
$ dash echotest.sh
-e 123
You are probably on some Ubuntu-like OS, where /bin/sh redirects to dash. That would explain the error around "-". So if you are using echo, set you shell specificially or ensure that your script works on all common shells.
Additionally, you are messing up your quotations
echo -e 'attach database 'testdatabase.db' as 'aj';\n.separator ","\n.import /home/aj/ora_exported.csv qt_ora_exported'
results in (no quotations in the first line)
attach database testdatabase.db as aj;
.separator ","
.import /home/aj/ora_exported.csv qt_ora_exported
but you pobably want
echo -e "attach database 'testdatabase.db' as 'aj';\n.separator ','\n.import /home/aj/ora_exported.csv qt_ora_exported"
It looks strange that you are using external script to update database!
why you don't pass "ora_exported.csv" file name as a script argument? This would help solve the problem.
I was talking (typing) about this solution:
void MainWindow::on_importButton_clicked()
{
QProcess::startDetached("/bin/sh",
QStringList()<<"/home/aj/script.sh",
"<location of: 'ora_exported.csv' file>");
}

Sqlite Mode Error When Running Script with Output Redirection

I have the following shell script
cat <<EOF | sqlite3 /path/to/my/db.sqlite
.mode line;
select item from mytable;
EOF
When running the script with output redirection, I get this error:
Error: mode should be one of: column csv html insert line list tabs tcl
This happens also when I try different modes. When I run the script without output redirection (printing to terminal), it works fine. What's going on?
Figured it out-- actually the same error was being thrown without output redirection, but I was missing it because normal output was being dumped to the screen instead of a file. The problem in my script is that there should be no ; after mode line.
