How do I concatenates the text files called first.doc and second.doc and writes the result to final.doc under Ubuntu Linux operating systems?

You need to use the cat command to show a text file or concatenates the text files under Ubuntu or Unix like operating systems. The syntax is as follows to see the contents of the file foo.txt in the current directory to screen:
Tutorial details
DifficultyEasy (rss)
Root privilegesNo
RequirementsNone
Estimated completion timeN/A

cat foo.txt

To concatenates the text files the syntax is:

cat file1 file2 > file3

The output redirector (>) symbol used to redirect output of two files to the file3.

Example

Create a file called first.doc, enter:

 
echo 'This is a test and stored in first.doc file.' > first.doc
cat first.doc
 

Create a file called second.doc, enter:

 
echo 'This is a test and stored in second.doc file.' > second.doc
cat second.doc
 

Verify both file exists in the current directory with the ls command:

 
ls *.doc
 

To concatenates both files and store the result to final.doc, enter:

 
cat first.doc second.doc > final.doc
ls -l *.doc
cat final.doc
 

Sample outputs:

Well, *this* is completely useless when dealing with actual .doc files in the wild (which are pretty much always Microsoft Word files).
