install
INSTALL(1) User Commands INSTALL(1)NAME
install - copy files and set attributes
SYNOPSIS
install [OPTION]... [-T] SOURCE DEST
install [OPTION]... SOURCE... DIRECTORY
install [OPTION]... -t DIRECTORY SOURCE...
install [OPTION]... -d DIRECTORY...
DESCRIPTION
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.
--backup[=CONTROL]
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
--strip-program=PROGRAM
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-context
preserve SELinux security context
-Z, --context=CONTEXT
set SELinux security context of files and directories
--help display this help and exit
--version
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
