install
install [options]  [source]  destination
System administration command. Used primarily in Makefiles to update files. install copies files into user-specified directories. Similar to cp, but attempts to set permission modes, owner, and group. The source may be a file or directory, or a list of files and directories. The destination should be a single file or directory.
Options
-b, --backup[=control]
Back up any existing files. When using the long version of the command, the optional control parameter controls the kind of backup. When no control is specified, install will attempt to read the control value from the VERSION_CONTROL environment variable. Accepted values are:
none, off
Never make backups.
numbered, t
Make numbered backups.
existing, nil
Match existing backups, numbered or simple.
simple, never
Always make simple backups.
-d, --directory
Create any missing directories.
-g group, --group group
Set group ID of new file to group (privileged users only).
--help
Print help message, then exit.
-m mode, --mode mode
Set permissions of new file to mode (octal or symbolic). By default, the mode is 0755.
-o [owner] , --owner[=owner]
Set ownership to owner or, if unspecified, to root (privileged users only).
-p, --preserve-timestamps
Preserve access and modification times on source files and directories.
-s, --strip
Strip symbol tables.
-v, --verbose
Print name of each directory as it is created.
--version
Print version, then exit.
-C
Do not overwrite file when the target exists and is identical to the new file. Preserve original timestamp.
-D
Create leading components of destination except the last, then copy source to destination.
-S suffix, --suffix=suffix
Use suffix instead of the default backup suffix, usually ~.
