Empty file check
Hi gurus ,


I have two files and i want to perform different action based on the condition if both or either is empty

HTML Code:
If [ File 1 is not empty && File two is not empty ]
 then 
 Do something 
 elif [ file 1 is empty && file 2 is not empty ]
 then 
 do something 
 elif [ file 1 is not empty && file 2 is empty ]
 then 
 do something 
 else 
 do something
 fi
I have tried the below bt its not working. only the first condition is getting evaluated
Code:
 if [[  -s "$f1"  && -s "$f2" ]]
 then
 echo " Both not empty"
 elif [[ ! -s "$f1"  && -s "$f2" ]]
 echo "First file empty and second not empty"
 elif [[  -s "$f1"  && ! -s "$f2" ]]
 echo "Fist file not empty and second file empty"
 else
 echo " Both Files empty"

LEARN ABOUT SUSE

glloadname

GLLOADNAME(3G)															    GLLOADNAME(3G)

NAME

       glLoadName - load a name onto the name stack

C SPECIFICATION

       void glLoadName( GLuint name )

PARAMETERS

       name  Specifies a name that will replace the top value on the name stack.

DESCRIPTION

       The  name stack is used during selection mode to allow sets of rendering commands to be uniquely identified.  It consists of an ordered set
       of unsigned integers.  glLoadName causes name to replace the value on the top of the name stack, which is initially empty.

       The name stack is always empty while the render mode is not GL_SELECT.  Calls to glLoadName while the render  mode  is  not  GL_SELECT  are
       ignored.

ERRORS

       GL_INVALID_OPERATION is generated if glLoadName is called while the name stack is empty.

       GL_INVALID_OPERATION is generated if glLoadName is executed between the execution of glBegin and the corresponding execution of glEnd.

ASSOCIATED GETS

       glGet with argument GL_NAME_STACK_DEPTH
       glGet with argument GL_MAX_NAME_STACK_DEPTH

SEE ALSO
