Can't we use "grep -w" ? as per my experience 10 examples of grep command in UNIX and Linux it matches whole word , so my understanding is that it should match exact word like "77" and not "777" , also we can use wc -l to count lines , this is what I did as quick test
$ cat abc
77
7777
777
77777


$ grep -w 77 abc | wc -l
1


$ grep -w 777 abc | wc -l
1
