MANAGING FILES

By using Unix commands and applications, you can create and manage files containing a variety of data. These commands allow you to move around the system's file tree to create, copy, rename, move, and delete etc.. The commands that we will use ion this section are listed below and must be used in lower case. This is because Unix is case

sensitive.

USING THE * WILDCARD CHARACTERS WITH MV, CP, AND RM Using the * wildcard characters with mv, cp, and rm. Wildcard characters are often useful when you want to move or copy multiple files from one directory to another. For example, suppose you have two directories immediately below your current directory, named 'new' and 'old', and these directories contain the following files: % ls new

DNS AND NAMED

Question 2: See it working. Start up the NAMED service (named.service) and check that it works. If you have been playing with the firewall configuration you will need to reset the firewall settings to the defaults. do that with: systemctl restart iptables. To start NAMED run "systemctl start named.service". THE PARENT DIRECTORY The Parent Directory. The parent directory is the directory above the current directory in the naming tree. For example, if your current directory is /home/john/projects then the parent directory is /users/john. Your parent directory may be referred to as .. (double dot). In any directory if you type ls with the option '

WILDCARD CHARACTERS

Wildcard. Wildcard characters provide a convenient shorthand for specifying multiple file or directory names with a single name. Two of the most useful wildcard characters are the * and the ?. The * matches any arbitrary character string (including the null character), and the ? matches any single character. THE BRACKET () WILDCARD CHARACTER The Bracket ( ) Wildcard Character. The third type of wildcard is actually a pair of square bracket characters. This wildcard is an expansion matching any single character or range of characters separated with a dash ('-') listed within the brackets. For example. Notice the - character specifies a range.

INTRODUCTION

Linux is a powerful server platform. Many web sites use Linux as the operating system. Servers also provide the facilities to manage domain names, email, and remote access technologies. Many of the day-to-day activities you perform on the web relies heavily on server technologies, and in turn many of these are based on Linux.

FILE ACCESS

File Access. Welcome to linuxzoo. Essential Linux. Unix Security. File Access; Access to Unix files are governed by ownership and permissions. If you create a file, you are automatically the owner of that file, and can set the permissions for that file to give or deny access to other users of the system.

ESSENTIAL ADMIN

Essential Unix Administration. User: Password: We look at some of the commands that the User Administrator needs. In this tutorial you will encounter a number of Linux commands that you may not have seen before, use the man command on your system to find out more about any Linux command that you are unsure of. TUTORIAL 5 - LINUXZOO Question 13: find new files. Find all the files and directories in the demo directory that are newer than s1 . Send the output of the command to /var/tmp/t1 (don't send it to the demo directory). The names of the files should appear as full names. For example, the file "s5" would appear as "/home/demo/s5". STANDARD INPUT/OUTPUT AND REDIRECTION Standard Input/Output and Redirection. Unix uses the keyboard and the terminal screen for its standard input and output devices. It always expects input from the keyboard and sends output to the terminal unless you tell it differently. You can send any screen output to a file in your directory by using redirection in the command line to

The * matches any arbitrary character string (including the null character), and the ? matches any single character. ORDERING FILES USING SORT Ordering files using sort. You can use the sort command to order the contents of files, sorting alphabetically, numerically, or by different fields. The sort command displays sorted file contents on a line-by-line basis. It compares the first characters in each line; if they are the same, it compares the next characters in turn, and so on WEEK 1A - GENTLE REVISION The "cd" command changes your current directory. On its own it changes it to your HOME directory, otherwise you need to specify a parameter which either is an absolute directory (such as cd /home) or a relative directory (such as cd dir1 which takes you to dir1 in your current

working directory).

In this tutorial you will encounter a number of Linux commands that you may not have seen before, use the man command on your system to find out more about any Linux command that you are unsure of. TUTORIAL 4 - LINUXZOO If you have just completed all the previous tutorials you need not use this setup button. However, if you have skipped part or all of the previous tutorial questions, or when you ran your virtual machine the demo account was missing, then the button below will create the demo account and create the files which the previous tutorials would have

had you create.

USER AUTHENTICATION IN APACHE The htpasswd command allows you to create the file, and to add users to the file. Use it to create a basic authentication password file called "/home/tom/webpasswd". Put into this file two users with the following passwords: User: richard Password: pass1 User: harry Password: pass2. Make sure that the password file is world readable. VI EXAMPLE - LINUXZOO The "~" character in the window indicates that that line currently does not exist. As the file is new no line exists, so this image gives you an idea what an empty file looks like in vi. STANDARD INPUT/OUTPUT AND REDIRECTION Standard Input/Output and Redirection. Unix uses the keyboard and the terminal screen for its standard input and output devices. It always expects input from the keyboard and sends output to the terminal unless you tell it differently. You can send any screen output to a file in your directory by using redirection in the command line to ORDERING FILES USING SORT Ordering files using sort. You can use the sort command to order the contents of files, sorting alphabetically, numerically, or by different fields. The sort command displays sorted file contents on a line-by-line basis.
