[zhenghui@node10 ~]$ sh_upd_stnfo
======================================================================

 Update station.info using header infomation from RINEX file
                           and/or
 Update station.info by merging and sorting entries from other station.info's

 Usage: sh_upd_stnfo -ref <rsfile> -l <sitelist> -merge <sfiles> -files <rfiles> -i <ifiles> -x <snxfiles>  -xs <snxsite>
    -replace <replace_option> -rxo -nodup -w <outfile> -l <sitelist> -apr -nosort -c  -h <slant hgt> -t <dup_tol>

        <rsfile>  Reference station.info (defines output info and format). [default station.info]
               If not given and station.info does not exist, a new station.info file will be created with the format:
*SITE  Station Name      Session Start      Session Stop       Ant Ht   HtCod  Ant N    Ant E    RcvCod  SwVer  AntCod

        <sitelist> file containing list of stations to be included from reference station.info
               If omitted, include all.
               If 'sd' create a list ('stnfolist') from the sites with the ftprnx token in sites.defaults
               if 'rnx' create a list from the files in the [experiment]/rinex directory
               if 'sdrnx' create a list from both sites.defaults and the rinex directory
                  -- for these option, you must run sh_upd_stnfo from the [experiment]/tables directory
               If another name, read this file (can be run from any directory).
               The sitelist file is a single column of 4-character names in columns 2-5

        <rfiles> RINEX file(s) to be used to update station.info (full path and wildcard allowed)

        <sfiles> station.info files to be merged with the reference file (values from merged files take precedence

        <ifiles> IGS log file(s) to be used to update station.info (full path and wildcard allowed)

        <snxfiles>  SINEX files to be used to update station.info; see -xs (full path allowed)
        <snxsite>   site from SINEX file to be added; default is to add all sites

        <replace_option>  Set value-checking for RINEX and single-site SINEX files:
            <diff> (default) add a new entry only if the values are different
            <all>  add a new entry even if values are the same (may result duplicates)
            <none> check values but do not add the new entry (user should compare values)

        -rxo  make any new RINEX entries open-ended (may fail if existing later entries for site)

        -nodup  do not write out duplicate or overridden entries (default is to write as comment)

        <outfile> new station.info from a merge (default station.info.new, renamed to station.info)

        -apr   write an output apr file from the coordinates in the RINEX header, IGS log, or SINEX file

        -nosort option not to sort the output station.info (use only when confident of time order and no duplicates)

        -c  Copy all comments to the new station.info

        <slant hgt> antenna height (m) above which the height in the rinex will be
               as a slant height.  NOTE: Use with caution; not consistent with
               RINEX standard and is included only for non-standard RINEX files

        <dup_tol>  Tolerance in seconds for deciding whether two entries are the same (default 120s)

    NOTES:  There are three modes:
             (1) Merge station.info files, one or more inputs, one output
                  sh_upd_stnfo -ref station.info.sopac -merge station.info.regional -l sitelist -w station.info.s3
                    (default output is 'station.info.new')
                     If the sdrnx option is used for the sitelist, must be run from [expt]/tables
             (2) Incorporate information from a single RINEX file, IGS log file or SINEX file
                  sh_upd_stnfo -ref station.info -i drao.log -w station.info.drao
                    (default output is 'station.info.new')
             (3) Add information from multiple RINEX or IGS log files
                   sh_upd_stnfo -files *.99o
                 Continuous update of input file or specified output file.  Original input file save as
                 [input-file].orig for safety
