awk '/FIRST/ && !/SECOND/ {print FILENAME}' file_file_file*
 
Here I have names of files like file_file_file1, file_file_file2 and file_file_file3.

file_file_file1

find . -type f |awk '/FIRST/ && !/SECOND/ {print FILENAME}'

grep  FIRST File[0-9].txt | grep -v SECOND

grep  FIRST File[0-9].txt|grep -v SECOND|sed s/\:/' '/g|awk '{print $1}'

awk '/FIRST/ && !/SECOND/{print FILENAME}' $(find /<path/to/files> -name 'File*.txt' -type f 2>/dev/null)

for F in F*txt;do  if grep -q FIRST $F; then grep -qv SECOND $F && echo $F; fi; done

[sea@P50 ~]$ ll F*
-rw-rw-r--. 1 sea sea 15 15. Apr 16:46 File1.txt

-rw-rw-r--. 1 sea sea 10 15. Apr 16:46 File3.txt
