<h2>Use: install binaries, move or copy files</h2>
<p>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.
An alternate backup suffix may be specified via the -B option's argument.
Basic syntax is in the form <code>install [OPTION]... SOURCE DEST</code>
<br><code>$install -D /source/folder/*.xyz /destination/folder</code><br>
this line of code copies all .xyz file from /source/folder to
/destination/folder</p>
<p>
Here are just some of the most useful options for this command:
<ul>
<li>-b<br></li>
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>-C<br></li>
Copy the file. If the target file already exists and the files
are the same, then don't change the modification time of the target
<li>-d<br></li>
Create directories. Missing parent directories are created as
required.
<li>-f<br></li>
Specify the target's file flags; see chflags(1) for a list of
possible flags and their meanings.
<li>-g<br></li>
Specify a group. A numeric GID is allowed.
<li>-m<br></li>
Specify an alternate mode. The default mode is set to rwxr-xr-x
(0755). The specified mode may be either an octal or symbolic
value;
<li>-o<br></li>
Specify an owner. A numeric UID is allowed.
