cat
is one of the most frequently used commands in Unix operating systems.
cat
is used to read a file sequentially and print it to the standard output.
The name is derived from its function to concatenate files.
Cat can also be used to create a text file.

Example

cat file.txt
Concatenate the content of the two files and display the result in terminal:

Tip: Using cat
on a directory will cause error, so make sure it's a readable file.
