sorry command is

grep -B 1 ^$ file | egrep 'x|Y|Z'

can u post sample data

grep -B 1 ^$ | egrep 'x|Y|Z' file

^$ for blank line and -B 1 prints blank line and before line

try this it may help you egrep -n '\(|x' list | sort -n

even if files are not sorted my method is efficient u can use this method any no of files

here is my small test time for taking grep method and my method
shell>wc -l file*
28684 file1
4993 file2
shell> time grep -f file1 file2 |wc -l
