Hi Ygor,

If I understand it correctly, your code reads the contents of the first file from line 33 onwards and then appends the same into file 2 from line 65 onwards.
The logic referring to the exact line number i.e. 33 for reading the contents from file 1 should work, but as far as appending the text in file 2 is concerned, it will not always be at line 65 as the contents of file 2 could be varying and hence the position. What I'm looking at is to append the text in file 2 right at the end (irrespective of number of lines in file 2) just inside the last closing paranthesis i.e. ')' in file 2. File 2 would always contain the closing paranthesis at the end and was wondering if we could use the same instead of hardcoding a specific line number to append the text.

Thanks for your time and your help is much appreciated.


Regards

dnicky

NAME

       file - determine file type

SYNOPSIS

       mfile] ffile] file ...

   UNIX 2003 (onwards) Synopsis
       mfile] Mfile] ffile] file ...

DESCRIPTION

       performs  a  series  of tests on each file in an attempt to classify it.  If file appears to be an ASCII file, examines the first 512 bytes
       and tries to guess its language.  If file is an executable file, prints the version stamp, provided it is greater than 0 (see the  descrip-
       tion of the option in ld(1)).

       uses  the  file to identify files that have some sort of that is, any file containing a numeric or string constant that indicates its type.
       Commentary at the beginning of explains the format.

   Options
       recognizes the following command-line options:

	      Use alternate magic file
			 mfile.

	      (UNIX 2003 onwards Only)
			 Use alternate magic file Mfile.  Do not apply default context-sensitive tests.

	      Check the magic file for format errors.
			 This validation is not normally carried out for reasons of efficiency.  No file classification is done when  this  option
			 is specified.

	      (UNIX 2003 onwards Only)
			 Apply position-sensitive tests from the default magic file, and default context-sensitive tests to the file.

	      Obtain the list of files to be examined from file
			 ffile.  classifies each file whose name appears in ffile.

	      Do not follow symbolic links.
			 From UNIX 2003 (onwards) environment, if is not specified and the is a symbolic link referring to a non-existent file, it
			 is identified as a symbolic link, as if has been specified.

	      Do not attempt to classify a regular file further.

	      If the option is specified with the option, option, or both, the concatenation of the position-sensitive tests  specified  by  these
	      options is applied in the order specified by the appearance of these options.

   Environment Variables
       determines the language in which messages are displayed.

       If is not specified in the environment or is set to the empty string, the value of is used as a default for each unspecified or empty vari-
       able.  If is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of

       If any internationalization variable contains an invalid setting, behaves as if all internationalization variables are  set  to	"C".   See
       environ(5).

   International Code Set Support
       Single- and multi-byte character code sets are supported.  However, all non-ASCII text files are identified as "data".

WARNINGS

       The command for a release interprets the core files for that particular release correctly.  Using the command on a core file generated on a
       different release will report incorrect results.
