RE: does "fs -put " create subdirectories?
Modifying the script to precede the put with a mkdir (which creates the missing subdirectories) fixes the issue.thanksJohn

Good point Harsh.  As a Linux Admin, I prefer the behavior of 2.x.  It allows me to see if I've made a mistake in my planned placement of files instead of blindly writing.

On 1.x, -put does mkdir the parent directories if they are non existent (akin to mkdir -p).

On 2.x, -put does not do this - we need the dir to pre-exist or mkdir'd before -put.
