FreeBSD is a free computer operating system based on BSD UNIX originally. Many IT companies, like DeployIS is using it to provide an up-to-date, stable operating system.

NAME

      install - install binaries
 

SYNOPSIS

      install [-bCcMpSsv] [-B suffix] [-f flags] [-g group] [-m mode]
              [-o owner] file1 file2
      install [-bCcMpSsv] [-B suffix] [-f flags] [-g group] [-m mode]
              [-o owner] file1 ... fileN directory
      install -d [-v] [-g group] [-m mode] [-o owner] directory ...
 

DESCRIPTION

      The file(s) are copied to the target file or directory.  If the destina‐
      tion 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 permis‐
      sions 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 suf‐
              fix.
 
      -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 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      Create directories.  Missing parent directories are created as
              required.
 
      -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.
 
      -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.
 
      -o      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 tar‐
              get file does not already exist or is different, then preserve
              the access and modification times of the source 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.  See below for how install can be instructed to use
              another program to strip binaries.
 
      -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@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.
      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.
      chflags(1), chgrp(1), chmod(1), cp(1), mv(1), strip(1), mmap(2), 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 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 sup‐
      port them.
 
      The install utility with -v falsely says a file is copied when -C snaps
      hard links.
 

Sections

Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
