Also the simple ls command defaultly sort the ouput by name even when skipping aliases \ls

To avoid this you can use a special option -f (may depends on your plateform) this will force ls to display all found entries WITHOUT ordering them ... which can be ... MUCH FASTER in some case.

That is why when used with wc -l , and especially for direcory containing numerous entries, the ls command should be used with such "nosort" option

try this : ls -fR /users/home 2>/dev/null | wc -l

... or on any other PATH containing a bunch of entries

look how fast it can be : more than 23000 entries in less than a sec !

Code:

[ctsgnb@shell ~/sand]$ date && ls -fR /users/home 2>/dev/null | wc -l && date
