I know I can do this in Bash: wc -l <<< "${string_variable}" Basically, everything I found involved <<< Bash operator. But in POSIX shell, <<< is undefined, and I have been unable to find an alternative approach for hours. I am quite sure there is a simple solution to this, but unfortunately, I didn't find it so far.
