hi guys, i have a question related to quoting but i am not sure how to formulate it...
lets say we want to simulate the following shell actions
so i make the following script
buidtags.sh
but it doesn't work...
i think the reason is that it skips file globbing, and considers *.sh to be a file, that (of course) can't be found! How can i make file globbing and double quotes coexist? in other words how can i make this example work?
thanks in advance for your time,
nicolas
PS: in quoting as a reference i use chap7 from "learning the bash shell 3rd edition" but i am relatively new to shell scripting.Is there any other good reference for bash?

The block below isn't a surprise:$ ls

$ echo '$x'
$x
$ echo "$x"

$But I found this block a bit bewildering:$ echo $x'

$I'm wondering why substitution wasn't performed on the $x, since it was unquoted (as far as I can tell).... (5 Replies)

Hi,
My first shell script is one that prints the five largest directories in a given directory. My current effort is as follows, it gives me the output I'd like, but I have to quote a globbed pathname, which seems wrong:

pam_chroot
PAM_CHROOT(8) BSD System Manager's Manual PAM_CHROOT(8)NAME
pam_chroot -- Chroot PAM module
SYNOPSIS
[service-name] module-type control-flag pam_chroot [arguments]
DESCRIPTION
The chroot service module for PAM chroots users into either a predetermined directory or one derived from their home directory. If a user's
home directory as specified in the passwd structure returned by getpwnam(3) contains the string ``/./'', the portion of the directory name to
the left of that string is used as the chroot directory, and the portion to the right will be the current working directory inside the chroot
tree. Otherwise, the directories specified by the dir and cwd options (see below) are used.
also_root Do not hold user ID 0 exempt from the chroot requirement.
always Report a failure if a chroot directory could not be derived from the user's home directory, and the dir option was not specified.
cwd=directory
Specify the directory to chdir(2) into after a successful chroot(2) call.
dir=directory
Specify the chroot directory to use if one could not be derived from the user's home directory.

The pam_chroot module and this manual page were developed for the FreeBSD Project by ThinkSec AS and NAI Labs, the Security Research Division
of Network Associates, Inc. under DARPA/SPAWAR contract N66001-01-C-8035 (``CBOSS''), as part of the DARPA CHATS research program.
