However, you decide to change from the C-shell to tsch. Your task in this lab is to: -Open /etc/pref_shell in vim -Modify the environmental variable line SHELL=/bin/csh to read SHELL=/bin/tcsh -Save changes -Use the set command to view a list of variables or use echo $variableName to show each one /root en_US.UTF-8 /bin/bash linux View the currently set environment variables to find the values below HOME LANG SHELL TERM use cat /root/.bash_profile or vi /root/.bash_profile to view contents PATH View the contents of the /root/.bash_profile file. What is the last word in the file? Use cat or vi to view file contents for /etc/shells /bin/ksh The /etc/shells file contains a list of shells that are available on the current system. View the contents of the file and answer the following question.

Which physical disk is the swap area on? Which disk partition is the swap area on? What is the beginning cylinder for the swap area? What is the allocated size of the swap area in blocks? Which physical disk is the boot disk on? Which disk partition is the boot disk on? Use: mkfs -t ext3 /dev/sdb1 You've installed a new hard drive and created a partition on the drive. Now you need to format the partition before you can save data on the new hard drive. Your task in this lab is to format the /dev/sdb1 partition with the ext3 file system. Use: mkfs -t ext4 /dev/sdc1 mkfs -t ext4 /dev/sdc2 You've installed a 3rd hard drive and created 2 partitions on the drive. Now you need to format both partitions. You task in this lab is to format the partitions with the ext4 file system. Use: mkswap /dev/sdb2 swapon /dev/sdb2 You recently upgraded your computer and added an entra 512 MB of RAM. Consequently, you want to increase you swap space by adding a new swap area. The second hard disk has an unused partiton (/dev/sbd2) that you want to format for the swap area. Your task in this lab is to: -Create a swap partiton on /dev/sdb2 -Activate the swap partition Use: mkdir /mnt/disk mount -t ext3 /dev/sdb1 /mnt/disk You recently installed and formatted a new hard drive in your system. It's device file name is /dev/sdb1. Now you want to mount the volume. Your task in this lab is to: -Create the /mnt/disk directory -Mount /dev/sdb1 to the /mnt/disk directory with the ext3 file system. Use: umount /root/newdrive mount /dev/sdb2 /mnt/drive2 The /dev/sdb2 volume is mounted to an uncommon mount point directory: /root/newdrive. You need to remove the volume from the /root/newdrive mount point and remount it to the /mnt/drive2 directory. Your task in this lab is to: -Unmount /dev/sdb2 from /root/newdrive -Mount /dev/sdb2 to /mnt/drive2 Use: mount /dev/dvd /media/dvd ls /media/dvd to verify You need to install a new application from DVD, however, the DVD drive (/dev/dvd or /dev/sr0) is not mounted. Your task in this lab is to mount the DVD-ROM drive to the /media/dvd directory. 1.2G 2.8G 52% Use the df -h command to answer the following questions: (Type info exactly as it is shown on the screen) How much space is used on /dev/sda2? How much space is still available on /dev/sda2? What percentage of space is used on /dev/sda1? 100 K ./.config 40 K You are logged on as Will Adams (wadams), and your working directory is /home/wadams. Use the du command to answer the following questions: How big is the /home/wadams directory? What is the largest directory in/home/wadams? What is the size of the ./.config/ibus/bus directory? Use: pwd /home/wadams What is your current working directory? Use: ls -l / 12586 Mar 15 2009 You need to view detailed information for the hr directory in the root (/) directory and answer the following questions: What is the directory size? What is the modified date? Use: ls -a /hr .sanford What is the name of the hidden directory in /hr? Use: mkdir /home/wadams/wh or Go to the directory you want to create things in and use mkdir wh then use ls -l /home/wadams/wh to verify You are preparing to manage a new project code named White Horse. You need to prepare directories for White Horse documents. You are logged in as user wadams. Your task in this lab is to create the following directories inside the /home directory for user wadams: -Create a directory called wh directly inside /home/wadams -Create three following directories in /home/wadams/wh: -plan -research -implement
