This is not an issue with the command, but the buffer used
by the O/S to store the comman line arguments. Standard
sizes are 4KB or 8KB (i.e., on page). If the command line
arg's exceed this size then the command cannot be started.
Classic case is a directory with too many files in it;
"ls" may work fine but "ls *" will blow up because the
shell's expanding "*" overflows the buffer.
If the file names are 500 char's long then you may have
problems with only 10 files in the directory [don't
laugh, I've seen it].
ls is partcularly bad about dealing with over-populated
dir's becuse it sorts the result, which can be expensive
in a 10 000 file diredtory; find does not sort anything
and is better suited to dealing with huge file lists.
