syntax help on ksh if

For some reasons, my if test is not working, even though I could echo the right flag value.

Anyway, the cp line always got executed no matter if the variable MOVE_FILE returns Y or N.

What is wrong?

Thanks!
MOVE_FILE=grep...
if [ "${MOVE_FILE}"  = 'Y' ];
then
echo "flag: ${MOVE_FILE}"
cp....
fi

first you don't need the ; after the if line
2nd use == rather = since I think some versions use it as the assign operator

I have tried those two variations, as well as Y, 'Y', and "Y". But it's still not working.

how the value is assigned to the variable? Can you share the code so I can look at it?

MOVE_FILE=""`grep '^eMvfl>' $LOG_FILE | head -n 1 | cut -d'>' -f2 | cut -d'<' -f1`

can you show the out put of

grep '^eMvfl>' $LOG_FILE | head -n 1 | cut -d'>' -f2 | cut -d'<' -f1

Also, why do you have "" before `grep '^eMvfl>' $LOG_FILE | head -n 1 | cut -d'>' -f2 | cut -d'<' -f1`

The output as it echo:
flag: Y

But I just found out when I gave N as input, the log file did not get to the echo line. Huh...

Also, the "" before grep is from my co-worker. I am still learning, and have no idea why they are in. And I will try to go wihtout them in a minute.

It turned out that error was from the grep line.
