b. Puts the file system catalog into edit mode for rapid deletion or insertion of files and directories
c. Concatenates 2 or more files together
d. Copies file properties

Answer 1

The Linux 'cat' command concatenates 2 or more files together and is used to display and combine file contents.

Step-by-step explanation:

The Linux "cat" command is used to concatenate and display the content of files. The correct answer to the question is c. Concatenates 2 or more files together. This command reads files sequentially, writing them to standard output. The 'cat' command can be used to display the contents of a file, combine files, and even create new ones.

For example, to concatenate two files named 'file1.txt' and 'file2.txt', you would use the following command:

cat file1.txt file2.txt > mergedfile.txt

The '>' symbol is used for redirection in the command line, and it directs the output of the concatenation into 'mergedfile.txt', effectively creating a new file containing the contents of both 'file1.txt' and 'file2.txt'.
