install - copy files and set attributes


   install [OPTION]... [-T] SOURCE DEST
   install [OPTION]... SOURCE... DIRECTORY
   install [OPTION]... -t DIRECTORY SOURCE...
   install [OPTION]... -d DIRECTORY...


   This   install   program   copies  files  (often  just  compiled)  into
   destination locations you choose.  If you want to download and  install
   a  ready-to-use  package  on  a GNU/Linux system, you should instead be
   using a package manager like yum(1) or apt-get(1).

   In the first three forms, copy SOURCE to DEST or multiple SOURCE(s)  to
   the existing DIRECTORY, while setting permission modes and owner/group.
   In the 4th form, create all components of the given DIRECTORY(ies).

   Mandatory arguments to long options are  mandatory  for  short  options

          make a backup of each existing destination file

   -b     like --backup but does not accept an argument

   -c     (ignored)

   -C, --compare
          compare  each  pair of source and destination files, and in some
          cases, do not modify the destination at all

   -d, --directory
          treat all arguments as directory names; create all components of
          the specified directories

   -D     create  all  leading  components of DEST except the last, or all
          components of --target-directory, then copy SOURCE to DEST

   -g, --group=GROUP
          set group ownership, instead of process' current group

   -m, --mode=MODE
          set permission mode (as in chmod), instead of rwxr-xr-x

   -o, --owner=OWNER
          set ownership (super-user only)

   -p, --preserve-timestamps
          apply access/modification times of SOURCE files to corresponding
          destination files

   -s, --strip
          strip symbol tables

          program used to strip binaries

   -S, --suffix=SUFFIX
          override the usual backup suffix

   -t, --target-directory=DIRECTORY
          copy all SOURCE arguments into DIRECTORY

   -T, --no-target-directory
          treat DEST as a normal file

   -v, --verbose
          print the name of each directory as it is created

          preserve SELinux security context

   -Z     set SELinux security context of destination file to default type

          like  -Z,  or  if CTX is specified then set the SELinux or SMACK
          security context to CTX

   --help display this help and exit

          output version information and exit

   The   backup   suffix   is   '~',   unless   set   with   --suffix   or
   SIMPLE_BACKUP_SUFFIX.   The  version control method may be selected via
   the  --backup  option  or  through  the   VERSION_CONTROL   environment
   variable.  Here are the values:

   none, off
          never make backups (even if --backup is given)

   numbered, t
          make numbered backups

   existing, nil
          numbered if numbered backups exist, simple otherwise

   simple, never
          always make simple backups
