then
if [ 'expr $curr_month - $file_month >= 3 ]
# here are errors, the ' is wrong AND not closed
# according the shell you start, >= is not valid
# did you realized, >=3 and >2 are the same ?
# i suppose should be '-gt 2'
then
mv $FILE /u006/r45647/Izza/xsltOutput/archiveprocess
<move the file to another directory>
# i don't understand this statement

fi

fi

done

can we use sen to pass the variable for $file_year or file month?
or it's easy use the cut only?
