Yup.

And to find the number of lines in a file requires reading the entire file.
So pick the tool and code you think applies. In UNIX there are usually several ways to do one thing.

simple way would be "cat file1.txt | wc -l "

Because it would prevent the file name from appearing in the output, which is what the original poster wanted.

Code:
$ wc -l file.txt
$ 42 file.txt

Code:
$ cat file.txt | wc -l
$ 42
