awk script
Current field length : 361 bytes

To the record , i am appending the filename and hard-coding batchid.

The record length has increased from 361 to 400 and since i will continue to get both files ie 361 and 400 length sizes
i want to write a program that can handle both of them.

To the new files i want to cut the string from 362 to 400 and append after the batch id and filename as shown below


Both Input and Output are fixed length files


Output File Layout
------------------
'1 - 361''filename''batch_id'

'1- 361''filename''batch_id''362-400'


Existing code
-------------

for file in /export/home/input/temp/abc[0-9][0-9].dat;do

nawk '/............B[HT]0/{print "HDR/TRLR " ctr++ " : " $0 ;next }
/............H10/{print $0 |" sed s/$/'`basename $file`BATCHID'/ >>/output/outfile.dat " } ' $file


done



New Code
--------

I am not sure if this logic is correct or i might have complicated it.Please suggest

for file in /export/home/input/temp/abc[0-9][0-9].dat;do

nawk '/............B[HT]0/{print "HDR/TRLR " ctr++ " : " $0 ;next }
/............H10/{bl = substr($0,1,361);el = substr($0,362); print bl '`basename $file`BATCHID' el >>/output/outfile.dat " } ' $file



Its treating bl '`basename $file`BATCHID' el >>/output/outfile.dat " as a string rather than as a variable.

Can we run a Unix command in awk program? coz replacing SED here is giving me all kinds of problems.

Please help

LEARN ABOUT MOJAVE

geom

geom(1) 																   geom(1)

NAME

       geom - analyzes a molecular geometry input in Cartesian coordinates.

DESCRIPTION

       The  program  geom  reads a set of Cartesian coordinates and determines from them the bond distances (Bohr and angstrom), bond angles, tor-
       sional angles, out-of-plane angles (optional), moments of inertia, and rotational constants.

FILES REQUIRED

	   input.dat	      - Input file
       and one of the following:
	   geom.dat	      - geometry file
	   file11.dat	      - PSI-format geometry/gradient file

FILES GENERATED

	   geom.out	      - file containing the analysis

INPUT OPTIONS

       The geom program has the following options:

       -h     Print help information (these options).

       -aces [filename]
	      Read the input in an ACES output format, with each line consisting of atomic symbol, atomic number, and  Cartesian  coordinates  (in
	      Bohr).  The optional argument is the name of the geometry input file, which defaults to geom.dat.

       -qchem [filename]
	      Read the input in an QCHEM output format, with each line consisting of the atom number, the atomic symbol, and Cartesian coordinates
	      (in Angstroms).  The optional argument is the name of the geometry input file, which defaults to geom.dat.

       -xyz [filename]
	      Read the input in an XYZ output format.  The first line contains the number of atoms and the second line is a comment line.   Subse-
	      quent lines each contain the atomic symbol and Cartesian X Y and Z coordinates (in Angstroms).  The optional argument is the name of
	      the geometry input file, which defaults to geom.dat.

       -oop   Print out-of-plane angles, where the angle a-b-c-d is defined as the angle formed by the vector a-d and the plane defined  by  atoms
	      b, c, and d.

       DO_OOP = boolean
	      Same as command-line switch -oop described above.

       ISOTOPES = matrix of reals/strings
	      Used to specify masses to be used in the calculation of the center of mass and rotational constants.  One array is provided for each
	      isotopomer to be calculated.  The arrays can mix floating point numbers with strings which designate isotopes.  If this array is not
	      given  and  file11.dat  is  present, then the masses will be obtained by converting the atomic numbers in file11.  If masses are not
	      given by ISOTOPES or by file11, then no mass-related quantities will be calculated.

       -g [filename]
	      Read Cartesian coordinates from a file other than file11.dat.  If a filename is not given, the default is geom.dat.  The alternative
	      file is assumed to be in a format similar to that of PSI's geom.dat.  Since such files do not contain atomic numbers, the moments of
	      inertia and rotational constants are not calculated if this option is used.

       READ_GEOM = boolean
	      This option in input.dat tells geom to read the geometry from geom.dat in the PSI geom.dat format.

       -a     Print parameters for all pair distances.

       PRINT_ALL_DIST = boolean
	      Same as -a flag described above.

       -d distance
	      Only print parameters involving pairs of atoms which are less than distance bohr apart (default value is 4.0 bohr).

       PRINT_DISTANCE = value
	      Same as -d flag described above.

       -angstrom
	      The input coordinates are in angstroms, not bohr.

       ANGSTROM = boolean
	      If TRUE, the input coordinates are in angstroms instead of bohr.	The default is FALSE.

	      The following example is for calculating the geometrical information for water with several different  isotopes.	 The  geometry	is
	      read from geom.dat rather than from file11.dat.

	      geom: (
		 read_geom = true
		 isotopes = (
		    (O H H)
		    (O D D)
		    (O18 1.007825 1.007825)
		  ) )
