ShellCheck found a done
keyword followed by a process substitution, e.g. done <(cmd)
.
The intention was most likely to redirect from this process substitution, in which case you will need one extra <
: done < <(cmd)
.
This is because <(cmd)
expands to a filename (e.g. /dev/fd/63
), and you need a <
to redirect from filenames.
