install - copy files and set attributes




install [OPTION]... [-T] SOURCE DEST
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 too.
  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, 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, --context=CONTEXT
  set SELinux security context of files and directories
--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
