Searching inside files in a script

[Khan Smith]

   I am running my script by sourcing it from my .bashrc.  But the
   distribution uses bash version 4.4.20.

   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.
