fldmap(1)(TDH)                                                  fldmap(1)(TDH)

NAME
       fldmap(1) - map fields by name from one file to another

SYNOPSIS
       fldmap  [-H] sourcefile  destfile

DESCRIPTION
       sourcefile and destfile are two tabular ascii files with field name
       headers.  This utility will write the contents of sourcefile,
       reformatted to the field format of destfile, to stdout.  This remapping
       is based on field names.  Both files must have a  field name header.

       A warning will be issued for any field found in sourcefile that is not
       in destfile, and such fields will not be present in the result.
       Destfile fields not present in sourcefile will be filled in as nulls
       (the = character by default but can be set to another symbol in  your
       config file ).

OPTION
       -H

              Include destfile's field name header in the output.

EXAMPLE
       Suppose file1 looks like this:
       id balance
       001 4504
       002 9403
       and file2 looks like this:
       id lastname firstname balance
       101 Smith George 58300
       103 Jones Jeff 4792
       If we issue the command: fldmap file1 file2 we will get the following
       on standard output:
       001 = = 4504
       002 = = 9403
       If we had used -H we would have gotten:
       id lastname firstname balance
       001 = = 4504
       002 = = 9403
