How to get file size in byte using wc -c

Question

when I use the command to get the file size in bye using wc -c the command return two values, the size in byte and the file name, ex: the output for wc -c my_file is 322 my_file I need to get only the first value to use it if condition, and I need to use this specific command not any other one.. Any help please, thank you.

`ls -s my_file | cut -d ' ' -f 1` could be faster especially for large files. — Abelisto, May 30 '20 at 16:03

Redirect stdin and wc wont know or echo the file name

wc -c < my_file

This can also be done without redirection or wastefully reading the whole file using stat:

stat -c %s my_file
