Now all I need to do is review it in detail to understand how it works and hopefully remember it, but that is a task for me.
Re reading back thru the thread I realised the first reply also has a working Output if the Output line enclosed the Variable in a another set of brackets.
I assume you knwo why, but can you explain why that format removes the leading space?
Thanks again
Ken
The arithmetic expansion of $(($x)) when $x expands to the string " 56" is 56.
Similarly, the parameter expansion of ${x##*[!1-9]} (which removes everything in the string before the 1st non-zero digit) when $x expands to the string "c 56" is also 56.

Hi All,
I have a vexing issue with leading spaces in file names. Basically, we're moving tons of data from our ancient afp file share to Box.com and Box forbids leading spaces in files or folders. The HFS file system seems to be perfectly fine with this, but almost all other Unix file systems... (1 Reply)
