To substitute multiple variable by their content in a file

Dear All,

I would like to instantiate a "pattern file" substituting "variable name" by their content.

Saying, we have:

1/ a "pattern file" containing different "variable name", the first character of the "variable name" is "@":

Code:

[x004191a@xsnl11p317a modl]$ cat TPTModl.txt
                              DEFINE OPERATOR FILE_READER_@OBJ_TBLNAME_CD
                              DESCRIPTION 'TERADATA PARALLEL TRANSPORTER DATA CONNECTOR PRODUCER OPERATOR'
                              TYPE DATACONNECTOR PRODUCER
                              SCHEMA SCHEMA_@OBJ_TBLNAME_CD
                              ATTRIBUTES
                            (
                              DirectoryPath                = '@DirectoryPath'
                            , ArchiveDirectoryPath         = '@ArchiveDirectoryPath'
                            , FileName                     = '@OBJFLOWPARM_FILEPATTERNDEFN_CD'
                            , Format                       = 'DELIMITED'
                            , TextDelimiter                = '@OBJFLOWPARM_FILETEXTDELIMITER_CD'
                            , EnableScan                   = 'Y'
                            , IndicatorMode                = 'N'
                            , TrimTrailingBlanks           = 'Y'
                            , TrimLeadingBlanks            = 'Y'
                            , OpenMode                     = 'Read'
                            );

2/ a variable with the list of the "variable name" with their value:

Code:

[x004191a@xsnl11p317a tmp]$ echo "$var"
@OBJ_DBNAME_CD:ABCD
@OBJ_TBLNAME_CD:EFGH
@OBJFLOWPARM_FILEPATTERNDEFN_CD:*_VERSFLDR.csv
@OBJFLOWPARM_FILETEXTDELIMITER_CD:$$

How would it be possible to produce an output file from the pattern input file with all the replacement done ?

Thanks a lot for your help and kind attention,

Didier.

dump

dump(n) 																   dump(n)

__________________________________________________________________________________________________________________________________________________

NAME

       dump - Dump information about Tcl interpreter in TkCon

SYNOPSIS

       dump method ?-nocomplain? ?-filter pattern? ?--? pattern ?pattern ...?

_________________________________________________________________

DESCRIPTION

       The  dump  command  provides  a way for the user to spit out state information about the interpreter in a Tcl readable (and human readable)
       form.  It takes the general form:

       dump method ?-nocomplain? ?-filter pattern? ?--? pattern ?pattern ...?

       The patterns represent glob-style patterns (as in string match pattern $str).  -nocomplain will prevent dump from throwing an error  if	no
       items matched the pattern.  -filter is interpreted as appropriate for the method.  The various methods are:

       dump command args
	      Outputs one or more commands.

       dump procedure args
	      Outputs one or more procs in sourceable form.

       dump variable args
	      Outputs  the values of variables in sourceable form.  Recognizes nested arrays.  The -filter pattern is used as to filter array ele-
	      ment names and is interepreted as a glob pattern (defaults to {*}).  It is passed down for nested arrays.

       dump widget args
	      Outputs one or more widgets by giving their configuration options.  The -filter pattern is used as to filter the config options  and
	      is interpreted as a case insensitive regexp pattern (defaults to {.*}).
