`install': Copy files and set attributes ======================================== `install' copies files while setting their permission modes and, if possible, their owner and group. Synopses: install [OPTION]... SOURCE DEST install [OPTION]... SOURCE... DIRECTORY install -d [OPTION]... DIRECTORY... In the first of these, the SOURCE file is copied to the DEST target file. In the second, each of the SOURCE files are copied to the destination DIRECTORY. In the last, each DIRECTORY (and any missing parent directories) is created. `install' is similar to `cp', but allows you to control the attributes of destination files. It is typically used in Makefiles to copy programs into their destination directories. It refuses to copy files onto themselves. The program accepts the following options. Also see Note: Common options. `-b' `--backup[=METHOD]' Note: Backup options. Make a backup of each file that would otherwise be overwritten or removed. `-c' Ignored; for compatibility with old Unix versions of `install'. `-d' `--directory' Create each given directory and any missing parent directories, setting the owner, group and mode as given on the command line or to the defaults. It also gives any parent directories it creates those attributes. (This is different from the SunOS 4.x `install', which gives directories that it creates the default attributes.) `-g GROUP' `--group=GROUP' Set the group ownership of installed files or directories to GROUP. The default is the process' current group. GROUP may be either a group name or a numeric group id. `-m MODE' `--mode=MODE' Set the permissions for the installed file or directory to MODE, which can be either an octal number, or a symbolic mode as in `chmod', with 0 as the point of departure (Note: File permissions). The default mode is `u=rwx,go=rx'--read, write, and execute for the owner, and read and execute for group and other. `-o OWNER' `--owner=OWNER' If `install' has appropriate privileges (is run as root), set the ownership of installed files or directories to OWNER. The default is `root'. OWNER may be either a user name or a numeric user ID. `-p' `--preserve-timestamps' Set the time of last access and the time of last modification of each installed file to match those of each corresponding original file. When a file is installed without this option, its last access and last modification times are both set to the time of installation. This option is useful if you want to use the last modification times of installed files to keep track of when they were last built as opposed to when they were last installed. `-s' `--strip' Strip the symbol tables from installed binary executables. `-S SUFFIX' `--suffix=SUFFIX' Append SUFFIX to each backup file made with `-b'. Note: Backup options. `--target-directory=DIRECTORY' Specify the destination DIRECTORY. Note: Target directory. `-v' `--verbose' Print the name of each file before copying it. `-V METHOD' `--version-control=METHOD' Change the type of backups made with `-b'. The METHOD argument can be `none' (or `off'), `numbered' (or `t'), `existing' (or `nil'), or `never' (or `simple'). Note: Backup options.
