run_rc_script()
{
      _file=$1
      _arg=$2
      if [ -z "$_file" -o -z "$_arg" ]; then
            err 3 'USAGE: run_rc_script file arg'
      fi

      unset       name command command_args command_interpreter \
            extra_commands pidfile procname \

      eval unset ${_arg}_cmd ${_arg}_precmd ${_arg}_postcmd

      case "$_file" in
      *.sh)                               # run in current shell
            set $_arg ; . $_file
            ;;
      *[~#]|*.OLD|*.orig|*,v)             # scratch file; skip
            warn "Ignoring scratch file $_file"

      *)                               # run in subshell
            if [ -x $_file ]; then
                     if [ -n "$rc_fast_and_loose" ]; then
                              set $_arg ; . $_file
                     else
                              ( trap "echo Script $_file interrupted; kill -QUIT $$" 3
                              trap "echo Script $_file interrupted; exit 1" 2
                              set $_arg ; . $_file )
                     fi
            fi
            ;;
      esac
}
请问其中case "$_file" in 的各分支*.sh) *[~#]|*.OLD|*.orig|*,v) *) 表示什么含义, _file代表一个文件名

man bash

word in [ [(] pattern [ | pattern ] ... ) list ;; ] ... esac
            A case command first expands word, and tries to match it against
            each pattern in turn, using the same matching rules as for path-
            name expansion (see Pathname Expansion below).  When a match  is
            found,  the  corresponding  list  is  executed.  After the first
            match, no subsequent matches are attempted.  The exit status  is
            zero if no pattern matches.  Otherwise, it is the exit status of
            the last command executed in list.
