Question

I have a source file source.txt. I wish to make a backup copy in the file ____. Which Bash command will accomplish this?

A) `cp source.txt backup.txt`
B) `backup.txt = source.txt`
C) `mv source.txt backup.txt`
D) `copy source.txt to backup.txt`

Answer 1

To make a backup copy of a file named source.txt on a Bash command line, use the command 'cp source.txt backup.txt'. This command creates a duplicate of the file while leaving the original file intact.

Step-by-step explanation:

The question is about making a backup copy of a file named source.txt using a Bash command. The correct Bash command to create a backup copy of a file is A) cp source.txt backup.txt. This command will copy the contents of source.txt into a new file called backup.txt, leaving the original file unchanged.

Option B) backup.txt = source.txt is incorrect because it is not a valid Bash command for copying files. Option C) mv source.txt backup.txt would move the file rather than copy it, meaning source.txt would no longer exist after the command. Lastly, D) copy source.txt to backup.txt is not the correct syntax for copying files in Bash.
