| git ls-files | egrep '\.erl|\.ex[s]$' | xargs cat | sed '/^$/d' | wc -l |
The sed command can be changed to sed '/^$\|^\s*#/d' to ignore comment only lines
@minhajuddin for some reason I get more lines with your regex ; I've also tried this one sed '/(?:^$)|(?:^\s*#)/d' which yields the same results as yours.
by piping twice, though, I get the comment lines removed, as in:
git ls-files | egrep '\.erl|\.exs?$' | xargs cat | sed '/^$/d' | sed '/^\s*#/d' | wc -l
Same command show following line counts for different Elixir releases:

- v1.10.4 152321

Command that worked for me on MacOS to count all LoC (including ex and exs files), ignoring blank lines and comments:
git ls-files | egrep '\.erl|\.exs?$' | xargs cat | sed '/^\s*$/d' | sed '/^\s*#/d' | less
