Error for "continue" keyword in Linux script.

Hi All

I have a function in a linux script like this

Code:

clean_up()
{
        db2 -x "UPDATE ${DB_SCHEMA_NAME}.ETL_DAILY SET ETL_STATUS = 'SUCCESSFUL' WHERE PROCESS_DATE = '${INT_RUN_DATE}' AND BATCH_NO = ${CM_BATCH} AND APP_ID = ${APP_ID} AND APP_VERSION = '${APP_VERSION}'" > ${TMPOUT}
        [ `grep SQLSTATE ${TMPOUT} | wc -l` -gt 0 ] && echo `date`": Failed:       ${DB_SCHEMA_NAME}.ETL_DAILY: UPDATE failed" && fclean_up "${DB_SCHEMA_NAME}.ETL_DAILY: UPDATE failed" && return 0
        echo `date`": Info:         `basename $0`: Completed Successfully !" && echo `date`": Info:         `basename $0`: Completed Successfully !" >> ${EXECUTION_LOG}
        [ -f $CM_dsload_prog_ind ] && rm $CM_dsload_prog_ind || continue
        [ -f $DIMJOBLST ] && rm $DIMJOBLST || continue
        [ -f $DIMJOBLST_COMMON ] && rm $DIMJOBLST_COMMON || continue
        [ -f $DIMJOBLST_ENABLED ] && rm $DIMJOBLST_ENABLED || continue
}

But at this function its throwing an error like this

Code:

  continue: only meaningful in a `for', `while', or `until' loop

Could you all please help me why this error is occuring and what would be the impact if i remove the continue keywords from this functions.

Thanks

break(1)							   User Commands							  break(1)

NAME

       break, continue - shell built-in functions to escape from or advance within a controlling while, for, foreach, or until	loop

SYNOPSIS

   sh
       break [n]

       continue [n]

   csh
       break

       continue

   ksh
       *break [n]

       *continue [n]

DESCRIPTION

   sh
       The break utility exits from the enclosing for or while loop, if any. If n is specified, break n levels.

       The continue utility resumes the next iteration of the enclosing for or while loop. If n is specified, resume at the n-th enclosing loop.

   csh
       The  break  utility  resumes  execution after the end of the nearest enclosing foreach or while loop. The remaining commands on the current
       line are executed. This allows multilevel breaks to be written as a list of break commands, all on one line.

       The continue utility continues execution of the next iteration of the nearest enclosing while or foreach loop.

   ksh
       The break utility exits from the enclosed for, while, until, or select loop, if any. If n is specified,	then  break  n	levels.  If  n	is
       greater than the number of enclosing loops, the outermost enclosing loop shall be exited.

       The  continue utility resumes the next iteration of the enclosed for, while, until, or select loop. If n is specified then resume at the n-
       th enclosed loop. If n is greater than the number of enclosing loops, the outermost enclosing loop shall be used.

       On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:

       1.  Variable assignment lists preceding the command remain in effect when the command completes.

       2.  I/O redirections are processed after variable assignments.

       3.  Errors cause a script that contains them to abort.

       4.  Words that follow a command preceded by ** that are in the format of a variable assignment are expanded with the same rules as a  vari-
	   able  assignment.  This means that tilde substitution is performed after the = sign, and also that word splitting and file name genera-
	   tion are not performed.
