What ever the result and the error both are always stored in result.txt
err.txt is created every time but remains blank!!!
Hi.

I would not expect it to work, as sqlplus does not write to standard error (2>...). Your best bet is probably to parse the one output file you do get, for errors.

lpq

LPQ(1)							    BSD General Commands Manual 						    LPQ(1)

NAME

     lpq -- spool queue examination program

SYNOPSIS

     lpq [-al] [-P printer] [-w maxwait] [job# ...] [user ...]

DESCRIPTION

     lpq examines the spooling area used by lpd(8) for printing files on the line printer, and reports the status of the specified jobs or all
     jobs associated with a user.  lpq invoked without any arguments reports on any jobs currently in the queue.

     Options:

     -P      Specify a particular printer, otherwise the default line printer is used (or the value of the PRINTER variable in the environment).
	     All other arguments supplied are interpreted as user names or job numbers to filter out only those jobs of interest.

     -l      Information about each of the files comprising the job entry is printed.  Normally, only as much information as will fit on one line
	     is displayed.

     -a      Report on the local queues for all printers, rather than just the specified printer.

     -w maxwait
	     Specify the maximum time to wait in seconds for remote responses.	The default is 300 seconds or 5 minutes.

     For each job submitted (i.e. invocation of lpr(1)) lpq reports the user's name, current rank in the queue, the names of files comprising the
     job, the job identifier (a number which may be supplied to lprm(1) for removing a specific job), and the total size in bytes.  Job ordering
     is dependent on the algorithm used to scan the spooling directory and is supposed to be FIFO (First in First Out).  File names comprising a
     job may be unavailable (when lpr(1) is used as a sink in a pipeline) in which case the file is indicated as ``(standard input)''.

     If lpq warns that there is no daemon present (i.e. due to some malfunction), the lpc(8) command can be used to restart the printer daemon.

ENVIRONMENT

     If the following environment variable exists, it is used by lpq:

     PRINTER  Specifies an alternative default printer.

FILES

     /etc/printcap	       To determine printer characteristics.
     /var/spool/output/*       The spooling directory, as determined from printcap.
     /var/spool/output/*/cf*   Control files specifying jobs.
     /var/spool/output/*/lock  The lock file to obtain the currently active job.

DIAGNOSTICS

     Unable to open various files.  The lock file being malformed.  Garbage files when there is no daemon active, but files in the spooling direc-
     tory.

SEE ALSO

     lpr(1), lprm(1), lpc(8), lpd(8)

HISTORY

     lpq appeared in 3BSD.

BUGS

     Due to the dynamic nature of the information in the spooling directory lpq may report unreliably.	Output formatting is sensitive to the line
     length of the terminal; this can results in widely spaced columns.
