What happened to the text file? Explain.
Redirect Outputs. a. Use the cd command to change to the /home/analyst/ (~) directory:
[analyst@secOps /]$ cd /home/analyst/ [analyst@secOps ~]$b. Use the echo command to echo a message. Because no output was defined, echo will output to the current terminal window:
analyst@secOps ~]$ echo This is a message echoed to the terminal by echo. This is a message echoed to the terminal by echo.c. Use the > operator to redirect the output of echo to a text file instead of to the screen:
analyst@secOps ~]$ echo This is a message echoed to the terminal by echo. > some_text_file.txtd. Notice that even though the some_text_file.txt file did not exist, it was automatically created to receive the output generated by echo. Use the ls -l command to verify if the file was really created:
[analyst@secOps ~]$ ls –l some_text_file.txt -rw-r--r-- 1 analyst analyst 50 Feb 24 16:11 some_text_file.txte. Use the cat command to display the contents of the some_text_file.txt text file:
[analyst@secOps ~]$ cat some_text_file.txt This is a message echoed to the terminal by echo.f. Use the > operator again to redirect a different echo output of echo to the some_text_file.txt text file:
analyst@secOps ~]$ echo This is a DIFFERENT message, once again echoed to the terminal by echo. > some_text_file.txtg. Once again, use the cat command to display the contents of the some_text_file.txt text file:
[analyst@secOps ~]$ cat some_text_file.txt This is a DIFFERENT message, once again echoed to the terminal by echo.
