chmod (Change File Mode): Change permissions for a file.

- Syntax: chmod mode file… * Where mode is the new file mode, and file is the name of a file or directory.

The first number represents the permission for the userid that wons the files; the second number represents the permissions for the userids in the group; the third number the permissions for all the userids on the system.

6 = permissions for owner
0 = permissions for group
0 = permissions for all other userids
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Use the following numeric value for the various permissions.

4 = read permission
2 = write permission
1 = execute permission
0 = no permission

Owner: read + write + execute = 4 + 2 + 1 = 7
Group: read + write = 4 + 2 + 0 = 6
Other: read = 4 + 0 + 0 = 4

State the course objective

Exposure to command-line tools and utilities.

In your own words, define what that objective entails.

The objective entails that throughout the course you will gain some, if not a lot of knowledge around the basics of command-line interfaces and the utilities involved with the type of interface.

State the method you will use for measuring successful academic/intellectual achievement of this objective.

The method of academic/intellectual achievement of this objective can only be done through the amount of usage(time) spent using a command line interface.

Follow your method and obtain a measurement. Document the results here.

This can be measured by how comfortable the user is with the language and syntax involved with CLI systems. The more commands you can remember the easier job it will be for the user to do his or her job.

Reflect upon your results of the measurement to ascertain your achievement of the particular course objective.

• How did you do?

So far I am learning about CLI, there wont be a point in which I know everything about CLI. Theres always something to learn about the subject at hand.

• Is there room for improvement?

Yes, there is always room for improvement.

• Could the measurement process be enhanced to be more effective?

The more you use a CLI the more effective you will be as a user. Knowing the commands is only part of the job, but correct implementation is the hard part.

• Do you think this enhancement would be efficient to employ?

Yes, broadening your horizon upon the multiple interfaces that computers can employ only make you a better end user.

• Could the course objective be altered to be more applicable? How would you alter it?

The course object is applicable at the moment, so alterations to the objective are not needed in current time.
