directory ...
DESCRIPTION
The file(s) are copied (or linked if the -l option is specified) 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.
The options are as follows:
-b 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.
-C 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.
-c Copy the file. This is actually the default. The -c option is
only included for backwards compatibility.
-d Create directories. Missing parent directories are created as
required.
-D destdir
Specify the DESTDIR (top of the file hierarchy) that the items
are installed into. This option is implemented for compatibility
with the NetBSD version of install and does nothing.
-f Specify the target's file flags; see chflags(1) for a list of
possible flags and their meanings.
-g Specify a group. A numeric GID is allowed.
-l linkflags
Instead of copying the file make a link to the source. The type
of the link is determined by the linkflags argument. Valid
linkflags are: a (absolute), r (relative), h (hard), s
(symbolic), m (mixed). Absolute and relative have effect only
for symbolic links. Mixed links are hard links for files on the
same filesystem, symbolic otherwise.
-M Disable all use of mmap(2).
-m 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; see chmod(1) for a description of possible mode values.
-N Use the user database text file master.passwd and group database
text file group from dbdir, rather than using the results from
the system's getpwnam(3) and getgrnam(3) (and related) library
calls.
-o Specify an owner. A numeric UID is allowed.
-p Preserve the modification time. Copy the file, as if the -C
(compare and copy) option is specified, except if the target file
doesn't already exist or is different, then preserve the
modification time of the file.
-S Safe copy. Normally, install unlinks an existing target before
installing the new file. With the -S flag a temporary file is
used and then renamed to be the target. The reason this is safer
is that if the copy or rename fails, the existing target is left
untouched.
-s install exec's the command strip(1) to strip binaries so that
install can be portable over a large number of systems and binary
types.
-U Indicate that install is running unprivileged, and that it should
not try to change the owner, the group, or the file flags of the
destination.
-v Cause install to be verbose, showing files as they are installed
or backed up.
By default, install preserves all file flags, with the exception of the
``nodump'' flag.
The install utility attempts to prevent moving a file onto itself.
Installing /dev/null creates an empty file.
ENVIRONMENT
The install utility checks for the presence of the STRIPBIN environment
variable and if present, uses the assigned value as the program to run if
and when the -s option has been specified.
If the DONTSTRIP environment variable is present, install will ignore any
specification of the -s option. This is mainly for use in debugging the
DragonFly dports(7) collection.
FILES
INS@XXXX If either -S option is specified, or the -C or -p option is
used in conjunction with the -s option, temporary files named
INS@XXXX, where XXXX is decided by mkstemp(3), are created in
the target directory.
EXIT STATUS
The install utility exits 0 on success, and >0 if an error occurs.
COMPATIBILITY
Historically install moved files by default. The default was changed to
copy in FreeBSD 4.4.
SEE ALSO
chflags(1), chgrp(1), chmod(1), cp(1), mv(1), strip(1), mmap(2),
getgrnam(3), getpwnam(3), chown(8)
HISTORY
The install utility appeared in 4.2BSD.
BUGS
Temporary files may be left in the target directory if install exits
abnormally.
File flags cannot be set by fchflags(2) over a NFS filesystem. Other
filesystems do not have a concept of flags. The install utility will
only warn when flags could not be set on a filesystem that does not
support them.
The install utility with -v falsely says a file is copied when -C snaps
hard links.
