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 suffix Use suffix as the backup suffix if -b is given. -b Back up any existing files before overwriting them by renaming them to file.old. See -B for specifying a different backup suffix. -C Copy the file. If the target file already exists and the files are the same, then do not change the modification time of the target. If the target's file flags and mode need not to be changed, the target's inode change time is also unchanged. -c Copy the file. This is actually the default. The -c option is only included for backwards compatibility. -D destdir Specify the DESTDIR (top of the file hierarchy) that the items are installed in to. If -M metalog is in use, a leading string of "destdir" will be removed from the file names logged to the metalog. This option does not affect where the actual files are installed. -d Create directories. Missing parent directories are created as required. -f flags Specify the target's file flags; see chflags(1) for a list of possible flags and their meanings. -g group Specify a group. A numeric GID is allowed. -h hash When copying, calculate the digest of the files with hash to rmd160 The RMD-160 cryptographic message digest. sha1 The SHA-1 cryptographic message digest. sha256 The 256-bits SHA-2 cryptographic message digest of the file. sha512 The 512-bits SHA-2 cryptographic message digest of the file. -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 metalog Write the metadata associated with each item installed to metalog in an mtree(8) "full path" specification line. The metadata includes: the file name and file type, and depending upon other options, the owner, group, file flags, modification time, and tags. -m mode 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 dbdir 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 owner Specify an owner. A numeric UID is allowed. -p Preserve the access and modification times. Copy the file, as if the -C (compare and copy) option is specified, except if the target file does not already exist or is different, then preserve the access and modification times of the source file. -S Flush each file to disk after copying. This has a non-negligible impact on performance, but reduces the risk of being left with a partial file if the system crashes or loses power shortly after install runs. Historically, -S also enabled the use of temporary files to ensure atomicity when replacing an existing target. Temporary files are no longer optional. -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. See below for how install can be instructed to use another program to strip binaries. -T tags -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 FreeBSD Ports Collection. FILES INS@XXXXXX Temporary files named INS@XXXXXX, where XXXXXX 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), getgrnam(3), getpwnam(3), chown(8) HISTORY The install utility appeared in 4.2BSD. BUGS The meaning of the -M option has changed as of FreeBSD 9.2 and it now takes an argument. Command lines that used the old -M will get an error or in rare cases will append logs to the first of multiple source files rather than installing it. Temporary files may be left in the target directory if install exits abnormally. File flags cannot be set by fchflags(2) over a NFS file system. Other file systems do not have a concept of flags. The install utility will only warn when flags could not be set on a file system that does not support them. The install utility with -v falsely says a file is copied when -C snaps hard links.
