Unix Commands

Today we learned many unix commands, all of which are important and all of which do different things. The combination of some commands yeilds different outcomes as compared to being used individually. Some commands that are used most frequently are whoami, which will return the user name of the person logged into Steel. Also, you can find out information from another person by inputting their username after the word finger. Finger will look up the other person's information and display it on the screen.

The command mkdir is used to make a directory, such as an informatics directory. To delete a directory, the command to use is rmdir.

Another helpful command is date, which will return the current date and time according to the computers internal clock.

The final command that I found helpful was the cal command which returns the calendar for that year. For instance, if I entered cal 4 2007, it will yield the month of April for the year 2007.
