Using GREP in IF Statement
Hello All,
I have 2 different pieces of code, I am confused why the Code1 is giving me the correct result where as the Code2 is not giving me correct result. It gives me always result as "Failure" irrespective of the "ERROR" word exists in logfile or not. may I know the reason why? I am using Bash shell in Linux OS.

Code1:
Code:
#!/bin/bash
sqlplus -s FCSDWH_STG/FCSDWH_STG@dwdev <<EOF > /home/infrmtca/bin/logfile
exec today_is;
EOF
        if `grep -q "ERROR" /home/infrmtca/bin/logfile` ;
        then
                echo "Success"
        else
                echo "Failure"
        fi

Code2:
Code:
#!/bin/bash
sqlplus -s FCSDWH_STG/FCSDWH_STG@dwdev <<EOF > /home/infrmtca/bin/logfile
exec today_is;
EOF
        if [ `grep -q "ERROR" /home/infrmtca/bin/logfile` ]
        then
                echo "Success"
        else
                echo "Failure"
        fi

My content of "/home/infrmtca/bin/logfile" is below
Code:
BEGIN today_is; END;

      *
ERROR at line 1:
ORA-06550: line 1, column 7:
PLS-00905: object FCSDWH_STG.TODAY_IS is invalid
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored

Thank you

ppi::statement::null

PPI::Statement::Null(3) 				User Contributed Perl Documentation				   PPI::Statement::Null(3)

NAME

       PPI::Statement::Null - A useless null statement

SYNOPSIS

	 my $foo = 1;

	 ; # <-- Null statement

	 my $bar = 1;

INHERITANCE

	 PPI::Statement::Null
	 isa PPI::Statement
	     isa PPI::Node
		 isa PPI::Element

DESCRIPTION

       "PPI::Statement::Null" is a utility class designed to handle situations where PPI encounters a naked statement separator.

       Although strictly speaking, the semicolon is a statement separator and not a statement terminator, PPI considers a semicolon to be a
       statement terminator under most circumstances.

       In any case, the null statement has no purpose, and can be safely deleted with no ill effect.

METHODS

       "PPI::Statement::Null" has no additional methods beyond the default ones provided by PPI::Statement, PPI::Node and PPI::Element.

SUPPORT

       See the support section in the main module.
