Julia,
        Add a script to determine if $COCCI is a directory. 
        If $COCCI is undefined, means first if branch success, then first if branch is executed. 
        If $COCCI is defined, means that fails, then elif branch is executed. And then, The elif branch judges whether $COCCI is a directory(based on "-d" option). 
        If it is a directory, the next statement is executed. If it is not a directory or if it is just a file with a a suffix of cocci, the statement after the final else branch is executed.
Thanks for you reply，
zhong.shiqi

Thanks for the contribution.  I'm not that knowledgeable about these
scripts.  What is the relation between the last two if branches?  If the
first one fails, does that mean that $COCCI has no definition?  In that
case, is the final else useful?

thanks,
julia
