jinlin:/windows/g/jinlin/linux_file/LINUX_ansys_90 # install
install: too few arguments
Try `install --help' for more information.
jinlin:/windows/g/jinlin/linux_file/LINUX_ansys_90 # install --help
Usage: install [OPTION]... SOURCE DEST           (1st format)
  or:  install [OPTION]... SOURCE... DIRECTORY   (2nd format)
  or:  install -d [OPTION]... DIRECTORY...       (3rd format)
In the first two formats, copy SOURCE to DEST or multiple SOURCE(s) to
the existing DIRECTORY, while setting permission modes and owner/group.
In the third format, 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)
  -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;  useful in the 1st format
  -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, only for 1st and 2nd formats
  -S, --suffix=SUFFIX override the usual backup suffix
  -v, --verbose       print the name of each directory as it is created
  -P, --preserve_context (SELinux) Preserve security context
  -Z, --context=CONTEXT  (SELinux) Set 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
