UNIX files can be viewed using the command
cat
This command will display the entire content of a text file. However, if the file is more than one page in length, then the information may scroll off the screen. To keep this from happening, you can use the command
more
The more command will pause after displaying a page of text, and you can go on to the next page of text by hitting the space bar.
You can also do a keyword search of the text by typing
/keyword
For example, if you were looking through a file using the more command, and wanted to skip to the word "drosophila" you would type
/drosophila
and the more command would search through the file until it found that word.
