If there are newline characters in any of the directories (and heaven forbid that there are!) the output of wc -l will be incorrect. May I suggest instead:
or:
The -b and -q switches suppress the output of "\n" as a character, replacing it with "?" or "\n" as strings respectively.The "-1" switch is redundant, but in my opinion makes it more readable - more obvious that we are expecting a single column out of ls. Either way, the output of wc -l is now the number of directories regardless of strange characters in their names.
