What happened to the text file? Explain.
Redirect and Append to a Text File.
a. Similar to the > operator, the >> operator also allows for redirecting data to files. The difference is that >> appends data to the end of the referred file, keeping the current contents intact. To append a message to the some_text_file.txt, issue the command below:
[analyst@secOps ~]$ echo This is another line of text. It will be APPENDED to
the output file. >> some_text_file.txt
b. Use the cat command to display the contents of the some_text_file.txt text file yet again:
[analyst@secOps ~]$ cat some_text_file.txt
This is a DIFFERENT message, once again echoed to the terminal by echo.
This is another line of text. It will be APPENDED to the output file
The new message was appended to the end of the file, keeping the original contents intact.
