cpio: Take a list of file names from standard input and add them [o]nto an archive in cpio's binary format.

echo

$ echo "${file1} ${file2} ${file3}" | cpio -o > ${archive-cpio}

try on your machine

This command consists of two parts:

echo "${file1} ${file2} ${file3}" - This part uses the echo command to print the values of three variables ${file1}, ${file2}, and ${file3}. The variables can be any file paths or names that you want to include in the cpio archive.
| cpio -o > ${archive-cpio} - This part uses the pipe (|) to redirect the output of the echo command to the cpio command. The cpio command is used to create an archive. The -o option specifies that it should create a new archive, and the > redirects the output of the cpio command to a file named ${archive-cpio}.

In summary, this command takes the values of three variables ${file1}, ${file2}, and ${file3}, and creates a cpio archive file named ${archive-cpio} which includes the contents of those three files.
