Pico explicit command list

Pico is an easy-to-use text editor on the CNS Logon Server that is designed to work in tandem with Pine e-mail. It can also be used with the Tin news reader and can be set as the default text editor for your Logon Server account.
You can start Pico two ways:

  • by activating the Pico hypertext link, under the Lynx menu called “Basic Services”
  • by typing in pico filename at the UNIX system prompt. Unlike many UNIX file editors, which require memorizing and typing a lot of commands on a command line, Pico works with key combinations based on the Control key (Ctrl).

Pico commands are usually given using the control <CTRL> keys. The most common commands appear in a menu at the bottom of the screen during a pico session. The menus are context sensitive and will vary depending on what you are doing within pico.

Pico Commands:

  • Ctrl-G  Get Help
  • Ctrl-X   Exit Pico saving buffer to specified filename
  • Ctrl-O  Write Out buffer into a file saving it and remaining in Pico

In this post i will show you what steps  I followed to adapt RAID1 on an existing installation of Debian Squeeze.

Step1. Make sure you have the following packages are installed:

apt-get update && apt-get upgrade
apt-get install mdadm rsync initramfs-tools grub-pc

Step2.  Partitioning the new drive:

First connect the new drive (/dev/sdb) and boot into your sistem.
Then use fdisk to display the partition informations for the existing drive (/dev/sda).

[email protected]:~# fdisk -l /dev/sda

Disk /dev/sda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0007384e

Device Boot Start End Blocks Id System
/dev/sda1 * 1 9330 74936320 83 Linux
/dev/sda2 9330 9730 3212289 5 Extended
/dev/sda5 9330 9730 3212288 82 Linux swap / Solaris

Now create partitions of the same size on the new drive.

NOTE:If the new drive is bigger leave the rest of the drive unpartitioned.

Step3. Create new degraded RAID1 arrays:
