Exam 010-160 Topic 18 Question 23 Discussion

Explanation
The correct command to copy the two files ending in .txt to the /tmp/ directory is cp *.txt /tmp/. This command uses the wildcard character * to match any number of characters beforethe .txt extension. Therefore, it will copy both texts 1.txt and texts 2.txt to the destination directory /tmp/. The other options are incorrect because they use different wildcard characters or syntax that do not match the desired files. For example, option A uses ?? to match exactly two characters before the .txt extension, but the files have a space and a number, which are not considered as one character. Option C uses a backslash \ to escape the dot . before the .txt extension, but this is unnecessary and will cause the command to fail. Option D uses ? to match exactly one character before the .txt extension, but the files have more than one character. Option E uses $? to match the exit status of the previous command before the .txt extension, but this is not relevant and will cause the command to fail123 References: 1: Linux wildcards | How do wildcards work in Linux with examples? - EDUCBA 2: Wildcards in Linux explained with 10 examples | FOSS Linux 3: What are wildcard characters in Linux? - Sage-Answers
