Unzipping files in unattended mode

When I use the unzip command from Linux machine and the files under ZIP already exists on my local directory, I get the interactive question: (if I want to replace the files from the ZIP with the existing files on my Linux machine

How to use the unzip command without this interactive question?

 [@superuser]# ls -ltr total 0 -rw-r--r-- 1 root root 0 Nov 15 15:13 all_my_files1 -rw-r--r-- 1 root root 0 Nov 15 15:13 all_my_files2

As the unzip(1l) man page states, pass -o to unzip in order to force overwriting of existing files without prompting.

You want the -o option:

unzip -o MY_FILES.zip

overwrites existing files without prompting. This is a dangerous option, so use it with care. (It is often used with -f, however.)
