LINUX CLASSES - FILES
How Do I Display the Contents of a Linux File?
Displaying File Contents
You know how to get a list of files. But what if you want to take a peek at a file's contents? Several commands, including cat,
more, and less, can be used to display files. Let's see how they work in this example:
$ cat pig_info
Pigs make great pets, but they are not dogs or cats. Maybe
somewhere in between. I tend to believe that they have more
personality. They do require significant amounts of attention,
love, and scratches. But they aren't always snuggly in return.
The cat command (short for concatenate) shown in this example is like the DOS type command. In response to the command
cat pig_info, the system simply splatters the file on the screen. If there is more data in the file than will fit on one screen, the
contents whiz by before you can see it. The more command solves this problem by displaying the file screen by screen:
$ more dog_info
Affectionately known as the "Toller," the Nova Scotian Duck
Tolling Retriever was once called the Little River Duck Dog,
since it was developed in the Little River district of Yarmouth
County, Nova Scotia. This engaging dog is a specialist with
waterfowl. Tolling, or luring, is the practice of tricking ducks
into gunshot range. Hunters had long observed this behavior
The more command pauses when the screen fills up and waits for you to press the spacebar before it rolls out another screenful of
text. A legend at the bottom of the screen tells you what percentage of the file has been displayed so far.
The less command works like more except that it lets you move both forward and backward in the file while the command is
running--use the B key on your keyboard to back up one screen and the spacebar to move forward and show the next screen.
You can press Q to quit the
Although all of these commands will let you view the contents of a file in different ways, none allow you to change the data in the
file. If you want to view and update a file, use one of the text editors discussed in the "Text Editors" section.
For more information on the cat command, see the
cat manual. (If you're not interested in cats, see the

A problem is that when I use less command to display a file, when I reach
the end a line appears: "END", and I can't use the terminal tab to type
other commands.I have to open a new tab.
There's a way to break? Neither with ctrl-c works.

Hello Bob, IŽam from venezuela and I want to ask you if you have your low
fat linux paper in pdf format and if is possible, that can I have it?
In advance tanks
I welcome your comments. However... I am puzzled by many people
who say "Please send me the Linux tutorial." This website *is* your Linux Tutorial! Read everything here, learn
all you can, ask questions if you like. But don't ask me to send what you already have. :-)
