Just before my brain packs up for the day:
(set 'f "/Users/me/folder 1/file 1") ; yes, spaces in pathnames...
(process (append "ls -l " f )) ; doesn't work
I need to pass some kind of quoted form of f to the shell. What's the best way of doing that?
Sorry if the question is a bit too simple...!
Hi Cormullion,
Does this thread perhpas help? ->

Regards, Norman.
Works fine for me:
> (set 'f "/Users")
"/Users"
> (process (append "ls -l " f))
1270
> total 0
drwxrwxrwt 4 root wheel 136 Oct 20 03:36 Shared
drwxr-xr-x 45 lutz lutz 1530 Dec 1 10:37 lutz
But it works better with 'exec', because you get the output returned in a list:
> (exec (append "ls -l " f))
("total 0" "drwxrwxrwt 4 root wheel 136 Oct 20 03:36 Shared"
"drwxr-xr-x 45 lutz lutz 1530 Dec 1 10:37 lutz")

and you also could do this:
> (directory "/Users/")
("." ".." ".DS_Store" ".localized" "lutz" "Shared")

Hi folks. Thanks for the replies. But the problem is with files and directories that have spaces in their names. (Perhaps this is a MacOS X-only thing?) So this works:
"/Applications/Firefox.app/"
but this doesn't:
"/Applications/Address Book.app/"
Loads of files and directories have spaces in, and I was looking for a way to quote them for the (process ) or (exec) functions.
Unix space you have to pre with an "" like in
{/this is a directory}
Enjoy...
Thanks. I've also just had this inspiration:
(set 'f "/Applications/Address Book.app/")
(exec (string "ls -l " (format "'%s'" f )))
- a way of putting single quotes round the string. If there's nothing better, that'll do nicely!
... and you could shorten that to:
(exec (format "ls -l '%s'" f ))
because format returns a string and can take other text besides format specs

Neat. Thanks.
