        I am running my script by sourcing it from my .bashrc.  But the

        Have installed bash version 5.1.8 which gets installed in
        /usr/local/bin/
        Can one install bash version 5.1.8 so it is the dafaulh or do I
     run the
        risk of having the OS apply an
        update to its own built-in Bash package?

        Try this:



        TIMEFORMAT='%R'

        tim=$( { time grep -r "${isufx[@]}" -e "$ptrn" -- "${fdir[@]}"
        >/dev/null; } 2>&1)



        TIMEFORMAT can also contain %U for user time or %S for system
     time
        (and some other stuff as well, see bash man page for details).
        If you wish to save the grep output, redirect it to a file rather
     than
        /dev/null.



   Wonderful, many you.
