Hello all!



Hope this is not a faq. My question seems easy, but the only solution
I found is a bit complicate. To list folders only, I have had first
the idea

% ls | grep ^d

which is not working here! I am on Macintosh OS 10.4.11 and my shell
is tcsh. Also quoting did not :

% ls | grep "^d"

Why? Ok! Then I tried these following perl solutions, which is a bit
complicate:

% ls -s | perl -e 'while (<>) {print if (/^\s*0/)}'

and this is working too:

% ls -l | perl -e 'while (<>) {print if (/^\s*d/)}'

is there a more elegant solution to this problem?



happy Eastern to all

In bash:
$ ls -d */
or as I prefer:
$ ls -1d */

Wow! this was a quick answer :-) And it is working too in my tcsh! And
now I realize, why my suggestion of

% ls | grep ^d

was not working!

It needs the switch of -l of course!


% ls -l | grep ^d

Sorry for the noise! And thanks to Salve

or with GNU find

$ find . -type d -maxdepth 1 -ls

Here's a couple of aliases

alias lsd '/bin/ls -aF | grep /$ | xargs /bin/ls -Cd'
alias ldir '/bin/ls -l|/bin/grep "^d"'
alias dir 'set d = `ls -1F \!* |grep /`; if ($#d) echo "$d:gh";unset d'

You have some good answers to your question already, but you might get
an even better answer if you say what you want a list of folders
for. I often find that a shell command is awkward not because of some
deficiency in the UNIX environment, but because the user requirement
is poorly understood.

So what do you need this folder list for?

should be ls -d -- */

It works in most shells, not only bash. But note that it lists
directories and symlinks to directories, it also adds a / to the
end of every file name.

zsh has globbing qualifiers to select files of certain types or
with certain attributes:

ls -ld -- *(/)

will select directories only.

ls -ld -- *(-/)

for directories or symlinks to directories.

ls -ld -- *(D-/)

also includes dot-dirs (hidden directories).

ls -ld -- *(oND-/)

to disable the sorting done by zsh (ls does the sorting already
anyway)

With find:

find . ! -name . -prune ! -name '.*' -type d -print

Or:

find . ! -name . -prune ! -name '.*' -follow -type d -print
(to include symlinks to directories)

or:

find . ! -name . -prune -follow -type d -print
(to include hidden dirs).

Merci Stéphane, très rafraîchissant tes suggestions :-) Pleins des
choses à apprendre! -prune je connaissais pas encore avec "find".


Thank you all, for your answers ... Have to read many man-pages
again :-)


Greetings from Munich

"if" without "then" and "fi"?

I think that's tcsh syntax.

tcsh> if (10 == 10) echo "ok"
ok

All the commands are tested with bash and GNU tools, so they may use
nonstandard features. I try to mention when something is nonstandard (if
I'm aware of that), but I may miss something. Corrections are welcome.
