The output is the name of files, one per line, that were accessed
during the expansion of the input file arguments.
The file arguments are excluded from the list.
If no input files are given, the standard input is read.

As a result,
may not be 100% reliable on these systems.
If the output seems to be missing essential files, this is
no doubt why.
The only fix is to put in a longer sleep time between the
call and the final
