   set +x turns tracing off.

   I am sourcing a number of scripts. Would "set -x" apply to the current
   file or to
   everything?  Where is best to set the command?  In the topmost srcipt?




   The setting will apply to any commands after it's set. Sourced files
   are executed as if the lines appeared directly in the file sourcing
   them. Place set -x and set + around any lines you want traced. You can
   use those settings wherever and as many times as you want. Narrowing
   their range will allow you to focus on areas of interest and limit the
   amount of output where it's not needed.

   That's fantastic functionality, I appreciate that.
