using flag inside a for loop to check condition
I have a logic like this
It initializes the flag variable as "T" at the beginning of the loop everytime
Inside each loop it checks for two conditions and updates the flag variable as "A" or "B"
In the end of the loop it checks for the value of the variable flag for "A" or "B" and execute different steps
This is not working as expected.What is the scope of the flag variable??

for filename in `<command will get list of files>`
do
flag="T"
if [ <checks for a condition A> ]
then
echo "Correct"
else
flag="A"
fi
if [ <checks for a condition B> ]
then
echo "Correct"
else
flag="B"
fi

if [[ flag == "A" || flag == "B" ]]
then
echo " Do nothing "
else
echo "Execute steps for flag T"
fi
done

smd-loop

smd-loop(1)						 Sync Mail Dir (smd) documentation					       smd-loop(1)

NAME

       smd-loop - iterates smd-pull and smd-push

SYNOPSIS

       smd-loop [-vt]

DESCRIPTION

       smd-loop  runs  smd-push and smd-pull at regular intervals as defined by the user in the ~/.smd/loop configuration file. On errors that are
       reported to be transient, it retries a second time before failing.

       The configuration file is line-oriented. Each line is composed of three space separated fields:	pull-frequency,  push-frequency  and  end-
       point-name. Frequencies are expressed in minutes, while endpoint name is a valid name for smd-pull(1) and smd-push(1). Lines beginning with
       # are considered as comments. The following example calls the command smd-pull default every 3 minutes,	and  smd-push  default	every  10.
       Example:

	   # pull-frequency push-frequency endpoint-name
	     3		    10		   default

OPTIONS

       -v     Increase program verbosity (printed on stderr)

       -t     Just create a template configuration file if none

FILES

       ~/.smd/loop

SEE ALSO

       mddiff(1), smd-server(1), smd-client(1), smd-push(1), smd-pull(1)
