小总结：Gamit中常见常用命令

按数据处理时先后要使用的：

1.基本命令：mkdir ， cp -r ***， ln -s ***， 等等

2.sh_get_nav ***, sh_get_orbits***, sh_get_rinex***

3.sh_crx2rnx -f ***

4.gftp更新表，或编写shell可实现大部分表的更新（需要学习的内容）

5.sh_setup *****

links.day 2013 031 TEST  连接处理数据所需要的各种年表

##############################################

    LINKS.DAY creates generic GAMIT links a day directory to an
    experiment tables directory
 
      e.g.  ut1.             ==> ../tables/ut1.
            l[expt][y].[day] ==> ../tables/lfile.
 
      Link of session.info is optional to allow creating a new one
      with MAKEXP.
 
      Use LINKS.COM to link directly to standard tables
 
 FORMAT
 
    links.day year day expt
 
 REQUIRED
 
    year, day, expt  = year, day-of-year, 4-char experiment name
                       for L-file linkname, set to l[expt][y].[day]
 
 EXAMPLE
 
    links.day 1992 181 trex
 
 
 NOTES:  1.  If you plan to run MAKEXP to produce session.info from
             input,  you must remove the link (rm session.info)
             after running this script and before running MAKEXP
 
         2.  Also links to a read-only "core" file in gs/tables to block
             HP machines from dumping core
 
         3.  Now links autcln.cmd to ../tables.  In order to protect saved
             manual edit_site_sv entries, however, an existing autcln.cmd
             file is not removed before attempting the link.
 
         4.  Query added Jan 98 to avoid overwriting station.info, session.info,
             sestbl., and sittbl.
