:* Learn the basic '''Linux command structure''' (''arguments'' and ''options'')
:* Learn how to get '''help''' for Linux commands via the '''online manual''' (i.e. '''man''' command).:* Learn Perform '''Basic Shell Editing''':* Learn how to perform setup '''online assignmentsassignment 1'''.:* Perform the '''first two sections section''' and '''3 parts of the second section''' of online assignment #1'''.<br><br>
===Part 1: Using the Linux Shell ===
:* a series of characters (i.e. '''text''') that the command can use
An '''argument''' is <u>separated</u> from a command (or from other arguments) by a '''SPACE''', '''multiple spacesMULTIPLE SPACES''' or a '''TAB'''.<br><br>
'''Perform the Following Steps:'''
With the Linux OS containing over '''2500''' commands and utilities, it is good for a Linux user or sysadmin to learn about how to use commands “on-the-fly”.<br><br>
The '''man''' command can provide information on how to use a command<br>(i.e. '''command usage''', '''acceptable command arguments''', '''command options''', '''examples''').<br><br>
# Issue the following command: <span style="font-family:courier;color:blue;font-weight:bold">man man</span><br><br>You may notice that the online manual categories commands into sections or '''numbered volumes'''.<br><br># Type the '''SPACE''' key to move to the next screen.<br><br>How many volume '''volume numbers''' are contained in the man pages (like '''executable commands''',<br>'''games''', or '''system administrator commands''')?<br><br>'''TIP:''' You can use the following '''short-cut keys''' within the man command to <br>help navigate throughout this utility to get help with the ls command (refer to table below):<br><br><table cellpadding="3"><tr><th style="border-bottom: 1px solid black;">Keyboard Shortcut</th><th style="border-bottom: 1px solid black;">Purpose</th></tr><tr><td>'''ENTER'''</td><td>Move down one line</td></tr><tr><td>'''SPACEBAR'''</td><td>Move one screen down</td></tr><tr><td>'''<ctrl><b>'''</td><td>Move one screen up</td></tr><tr><td>'''/pattern/'''</td><td>Search for Pattern</td></tr><tr><td>'''q'''</td><td>quit man utility</td></tr></table><br>
# Press the letter <span style="font-family:courier;color:blue;font-weight:bold">q</span> to exit the man command.<br><br>
# Issue the following Linux command to get help with the ls command: <span style="font-family:courier;color:blue;font-weight:bold">man ls</span><br><br>
# Issue the '''ls''' command for <u>each</u> of those option letters you noted in '''step 4''' to see how this command differs for each option.<br><br>'''NOTE:''' The '''man''' utility can be used with the '''-k''' option to help list Linux commands that match a text pattern<br>that is contained within the help screen for a Linux command.<br><br>
# '''Pipeline commands''' can be used to filter-out unnecessary output. In the next command that you will be issuing,<br>the output from the '''man -k''' command, is sent into the '''grep''' command to ''filter'' (i.e. ''trap'') only output that matches the pattern "8"<br>(The number "8" refers to the category of type of command - in this case, administration commands).<br><br>We will learn more about pipeline commands later in this course.<br><br>
# Issue the following Linux pipeline command: <span style="font-family:courier;color:blue;font-weight:bold">man -k copy user | grep 8</span><br><br>How does this ''pipeline command'' make it easier to obtain information regarding man command?<br><br>
# If you wish to change your password, you can change it by issuing the command: <span style="font-family:courier;color:blue;font-weight:bold">passwd</span><br>What option for the passwd command can be used to change user info (such as name)?<br>'''Hint:''' use the '''man''' command for '''passwd'''.<br><br>
# Press the letter <span style="font-family:courier;color:blue;font-weight:bold">q</span> to exit the man command.<br><br>'''NOTE:''' Do '''NOT''' run the ''passwd'' command. Unique for this college, your Matrix password is changed automatically when you change your '''myseneca''' password.<br><br>You will now learn how to perform '''command line editing''' to correct syntax errors while typing Linux commands PRIOR to pressing the ENTER key.<br><br>
'''Perform the Following Steps:'''
