I basically want an exact match of the line I am grepping for, the special characters and spaces are giving me errors. Or is there another method I could use?
Congratulations, you're the proud recipient of a UUOC Award. Remember, whenever you write 'cat filename | command' you can almost almost always rewrite this in a simpler way as 'command < filename'.
I'm guessing(since you didn't say) that it's complaining about bad parameters. It thinks your string is a switch since it starts with -. If you want to tell grep that the following option is a parameter and not a switch, you can add -- before it.

Hello,
When listing the file systems (using ls -ltr) , if the group names are longer the group name is getting truncated.

How could I list directories and sub... (5 Replies)

pam_wheel
PAM_WHEEL(8) Linux-PAM Manual PAM_WHEEL(8)NAME
pam_wheel - Only permit root access to members of group wheel
SYNOPSIS
pam_wheel.so [debug] [deny] [group=name] [root_only] [trust] [use_uid]
DESCRIPTION
The pam_wheel PAM module is used to enforce the so-called wheel group. By default it permits root access to the system if the applicant
user is a member of the wheel group. If no group with this name exist, the module is using the group with the group-ID 0.
OPTIONS
debug
Print debug information.
deny
Reverse the sense of the auth operation: if the user is trying to get UID 0 access and is a member of the wheel group (or the group of
the group option), deny access. Conversely, if the user is not in the group, return PAM_IGNORE (unless trust was also specified, in
which case we return PAM_SUCCESS).
group=name
Instead of checking the wheel or GID 0 groups, use the name group to perform the authentication.
root_only
The check for wheel membership is done only.
trust
The pam_wheel module will return PAM_SUCCESS instead of PAM_IGNORE if the user is a member of the wheel group (thus with a little play
stacking the modules the wheel members may be able to su to root without being prompted for a passwd).
use_uid
The check for wheel membership will be done against the current uid instead of the original one (useful when jumping with su from one
account to another for example).
MODULE TYPES PROVIDED
The auth and account module types are provided.
RETURN VALUES
PAM_AUTH_ERR
Authentication failure.
PAM_BUF_ERR
Memory buffer error.
PAM_IGNORE
The return value should be ignored by PAM dispatch.
PAM_PERM_DENY
Permission denied.
PAM_SERVICE_ERR
Cannot determine the user name.
PAM_SUCCESS
Success.
PAM_USER_UNKNOWN
User not known.
EXAMPLES
The root account gains access by default (rootok), only wheel members can become root (wheel) but Unix authenticate non-root applicants.
su auth sufficient pam_rootok.so
su auth required pam_wheel.so
su auth required pam_unix.so
