using test command

Hi all,
I am trying to expirement the test command here:

Code:

ahmed~>echo $LOGNAME
ahmed
ahmed~>test "$LOGNAME"="ahmed"
ahmed~>echo $?
0
ahmed~>test "$LOGNAME"="xyz"
ahmed~>echo $?
0

Why the command retruns zero in both cases ?

You need to separate the operands from the operator:

Code:

if test "$LOGNAME" = "ahmed"

This is usually done that equivalent but more readable way:

Code:

if [ "$LOGNAME" = "ahmed" ]
