The file(s) are copied to the target file or directory. If the destination
is a directory, then the file is copied into directory with its original
filename.  If the target file already exists, it is either renamed to
file.old if the -b option is given or overwritten if permissions allow.<br>
An alternate backup suffix may be specified via the -B option's argument.<br>
Basic syntax is in the form

<pre>
install [OPTION]... SOURCE DEST
</pre>

This line of code copies all .xyz file from <i>/source/folder</i> to <i>/destination/folder</i>

<pre>
install -D /source/folder/*.xyz /destination/folder
</pre>

<h3>Flags</h3>

    <li>-b: Back up any existing files before overwriting them by renaming
        them to file.old.  See -B for specifying a different backup suffix.
        (-B suffix Use suffix as the backup suffix if -b is given)</li>
    <li>-C: Copy the file.  If the target file already exists and the files
