Pgrep takes a process name and return a PID.

Note: pgrep looks through the currently running processes and lists the process IDs which matches the selection criteria to stdout. All the criteria have to match. For example, pgrep -u root sshd will only list the processes called sshd AND owned by root.

Incorrec answers:

ps bigscript: You can’t pass a name to ps, it interprets it as arguments.

A: How to Log In to the Zone Console Use the zlogin command with the -C option and the name of the zone, for example, my-zone.

global# zlogin -C my-zone

C: To disconnect from a non-global zone, use one of the following methods.

* To exit the zone non-virtual console:

zonename# exit

* To disconnect from a zone virtual console, use the tilde (~) character and a period:

zonename# ~.

B: Configure the AI install server to use a static IP address and default route. 

D: The create-service command can set up DHCP on the AI install server. If you want to set up a separate DHCP server or configure an existing DHCP server for use with AI. The DHCP server must be able to provide DNS information to the systems to be installed.

E: An automated installation of a client over the network consists of the following high-level steps:

1. The client system boots over the network and gets its network configuration and the location of the install server from the DHCP server.

2. The install server provides a boot image to the client.

3. Characteristics of the client determine which installation instructions and which system configuration instructions are used to install the client.

4. The Oracle Solaris 11 OS is installed on the client, pulling packages from the package repository specified by the installation instructions in the AI install service.

G: Install the AI tool set.

Use the installadm create-service command to create an AI install service. Give the service a meaningful name, and specify the path where you want the service created. Specify the source of the network boot image (net image) package or ISO file.

installadm create-service [-n svcname]

[-s FMRI_or_ISO] [-d imagepath]

-d imagepath

The imagepath is the location of the new install service. The install-image/solaris-auto-install package is installed to this location, or the specified ISO file is expanded at this location.

The zoneadm command is the primary tool used to install and administer non-global zones. Operations using the zoneadm command must be run from the global zone on the target system.

How to Install the solaris10 Branded Zone

A configured solaris10 branded zone is installed by using the zoneadm command with the install subcommand.

Example: global# zoneadm -z s10-zone install -a /net/machine_name/s10-system.flar –u

The /etc/passwd contains one entry per line for each user (or user account) of the system. All fields are separated by a colon (:) symbol. Total seven fields as follows.

1. Username: It is used when user logs in. It should be between 1 and 32 characters in length.

2. Password: An x character indicates that encrypted password is stored in /etc/shadow file.

3. User ID (UID): Each user must be assigned a user ID (UID). UID 0 (zero) is reserved for root and UIDs 1-99 are reserved for other predefined accounts. Further UID 100-999 are reserved by system for administrative and system accounts/groups.

4. Group ID (GID): The primary group ID (stored in /etc/group file)

5. User ID Info: The comment field. It allow you to add extra information about the users such as user's full name, phone number etc. This field use by finger command.

6. Home directory: The absolute path to the directory the user will be in when they log in. If this directory does not exists then users directory becomes /

7. Command/shell: The absolute path of a command or shell (/bin/bash). Typically, this is a shell. Please note that it does not have to be a shell.

Single quotes are most strict. They prevent even variable expansion. Double quotes prevent wildcard expansion but allow variable expansion. For example:

#!/bin/sh

echo $SHELL

echo "$SHELL"

echo '$SHELL'

This will print:

/usr/bin/bash

/usr/bin/bash

$SHELL

FLAGS

Indicates the status of each underlying interface, which can be one or any combination of the following:

(D) d indicates that the interface is down and therefore unusable.

(E) M indicates that the interface is designated by the system to send and receive IPv6 multicast traffic for the IPMP group.

Note:

i indicates that the INACTIVE flag is set for the interface. Therefore, the interface is not used to send or receive data traffic.

s indicates that the interface is configured to be a standby interface.

m indicates that the interface is designated by the system to send and receive IPv4 multicast traffic for the IPMP group.

b indicates that the interface is designated by the system to receive broadcast traffic for the IPMP group.

h indicates that the interface shares a duplicate physical hardware address with another interface and has been taken offline. The h flag indicates that the interface is unusable.

By default, the passwd command assumes a minimum length of six characters. You can use the PASSLENGTH default in the /etc/defaults/passwd files to change that by setting the minimum number of characters that a user's password must contain to some other number.
