The shell variable expansion ${var#pat} removes the shortest string from the start of the expansion of the variable var that matches the filename matching pattern specified by pat.
The shell variable expansion ${var##pat} removes the longest string from the start of the expansion of the variable var that matches the filename matching pattern specified by pat.
In both cases above, if there is no match for pat, var is expanded without modification.
With the pattern ??, the shortest string and the longest string are identical (and with filenames like P0xRy.fas, any of the following:
would expand to PxRy.fas.
