| Thanks for the tip & additional info. The results of the above after
| doing unalias ls and set -x:
|
| (directory names neutered slightly to protect the youngs)
|
| ls [^.]*/
| + ls 'My son'\''s Passion/' Desktop/ download/ 'Final Material/'
| ftools/ images/ 'Linux Forensic Documents/' LPIC/ 'Other son -
| Profession/' Photos/ PicasaDocuments/ Presentations/ scripts/ thumb/
|
| followed by the content of each of the above folders
So, as expected then, yes?
| The other two yield identical results, being:
|
| + ls -d 'My son'\''s Passion/' Desktop/ download/ 'Final Material/'
| ftools/ images/ 'Linux Forensic Documents/' LPIC/ 'Other son -
| Profession/' Photos/ PicasaDocuments/ Presentations/ scripts/ thumb/
|
| followed by the directory names above.
Good, also as expected.

I get what you get. We have established A) that "*/" and "[^.]*/"
are equivalent and B) that -d prevents burrowing into the directories.
We should have added:
ls */
to the tests above to try all four permutations.
Does it make sense now?

Kilimanjaro is a pretty tricky climb. Most of it's up, until you reach the
very, very top, and then it tends to slope away rather sharply.
