This is really bad, but seems to work.
Making the assumption that M or F will only appear once on each line
and separated by white space.

Code:
while read line
	do
	    if [[ $line == *M* ]]; then  
	    echo "$line"
	    ## cat to file	
	    fi
	    if [[ $line == *F* ]]; then
	    echo "$line"
	    ## cat to file
	    fi
	done < file
