Help completing lab.
Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!
1. The problem statement, all variables and given/known data:
Quote:
1. Start a command-line session with matrix.
2. Working from your
home directory create a directory named lab2b (use all lowercase letters)
3. Copy the Acceptable-Use-Policy file that resides in your home directory to your lab2b directory
4. Make lab2b your present working directory
5. Without changing working directories, list the contents of your home directory. Be sure that hidden files are also listed
6. Change directories to your home directory using the fewest possible keystrokes.
7. While in your home directory, create another directory called Labs (note that the "L" in "Labs" is uppercase).
8. Move your lab2b directory (including its contents) into Labs.
9. Use the tree command to verify the layout of your Labs directory. Your Lab directory structure should now look like this:
~
|
--------
|
Labs
|
-------
|
lab2b
|
-----
|
Acceptable-Use-Policy
Draw the above directory tree on a separate sheet of paper and keep updating it as you complete the following commands
Note: If the tree command output looks different, check your work for previous steps and redo them as needed.
10. Make lab2b your working directory
11. Working from lab2b, use the cat command to view the contents of the file called Acceptable-Use-Policy
12. Repeat the previous question using the more command. What did you notice that was different? Write down your observations.
13. Copy the /etc/group file to your present working directory (lab2b)
Note: under certain circumstances you may not be able to access the above file. In such case, use /home/uli101/group instead, noting the difference on your paper.

NAME
cd - change working directory
SYNOPSIS
[directory]
DESCRIPTION
If directory is not specified, the value of shell parameter is used as the new working directory. If directory specifies a complete path
starting with or directory becomes the new working directory. If neither case applies, tries to find the designated directory relative to
one of the paths specified by the shell variable. has the same syntax as, and similar semantics to, the shell variable. must have execute
(search) permission in directory.
exists only as a shell built-in command because a new process is created whenever a command is executed, making useless if written and pro-
cessed as a normal system command. Moreover, different shells provide different implementations of as a built-in utility. Features of as
described here may not be supported by all the shells. Refer to individual shell manual entries for differences.
If is called in a subshell or a separate utility execution environment such as:
(which invokes on accessible directories) does not affect the current directory of the caller's environment. Another usage of as a stand-
alone command is to obtain the exit status of the command.
EXTERNAL INFLUENCES
International Code Set Support
Single- and multi-byte character code sets are supported.
Environment Variables
The following environment variables affect the execution of
The name of the home directory,
used when no directory operand is specified.
A colon-separated list of pathnames that refer to directories.
If the directory operand does not begin with a slash character, and the first component is not dot or dot-dot, searches
for directory relative to each directory named in the variable, in the order listed. The new working directory is set
to the first matching directory found. An empty string in place of a directory pathname represents the current direc-
tory. If is not set, it is treated as if it was an empty string.
EXAMPLES
Change the current working directory to the directory from any location in the file system:
Change to new current working directory residing in the current directory:
or
Change to directory residing in the current directory's parent directory:
Change to the directory whose absolute pathname is
Change to the directory relative to home directory:
RETURN VALUE
Upon completion, exits with one of the following values:
The directory was successfully changed.
An error occurred. The working directory remains unchanged.
