Array inside sed

Hi guys

Let me at first describe the whole thing that I'm trying to do. Lets say I have 100 files like the following one.

HTML Code:

Ow            1230   16.000000   -0.834000   16.083957

Ow            1239   16.000000   -0.834000   10.477756                  
     11.91804137        -21.91087964        -11.56566494

I want to merge all the 100 files. The second field of the 1st,3rd..so on lines shows the atom number i.e 1230,1231. All the files are numbered from 1230..1239. So for the 1st file this numbers are ok, for the second file numbering should start from 1240,1241..and this should go on all the way through the last file. I did merge the files through a loop, The way I was trying to get those atom numbers in an array, replace those array elements with a counter. My thinking was this-

Code:

 myarr=($(awk 'NR % 2 ==1' TestMe | awk '{print $2}'))
echo ${myarr[@]} 
counter=1230; 
for i in "${myarr[@]}" 
do sed "s/$i/$j/g" TestMe;
counter=$(($counter+1)); 
done

I just don't know how to replace array elements in a sed command. Or is it the right way to loop through array elements. And whenever I tried to use that piece of code it said-

Code:

-bash: syntax error near unexpected token `counter=$(($counter+1))'

Thanks a lot!

LEARN ABOUT DEBIAN

fixnt

fixnt(1)							      Debian								  fixnt(1)

NAME

       fixnt - Filter for the Windows NT postscript printer driver.

SYNOPSIS

       fixnt < BADFILE.ps > GOODFILE.ps

DESCRIPTION

       The  Windows  NT  postscript  driver has a tendency to make broken postscript files, that are incompatible with psutils.  fixnt is a filter
       that fixes these problems, allowing the use of psnup(1).

       The filter takes the broken postscript file on stdin, and outputs a fixed postscript file on stdout.  It has no other form  for	invocation
       and takes no options on the command-line.

OPTIONS

       fixnt  takes no options.

BUGS

       fixnt does not check for NTPSOct94.  For a workaround, use a sed(1) command to replace 'NTPSOct94' with 'NTPSOct95', like so:
	      sed 's/NTPSOct94/NTPSOct95/g'
       This is particularly important for Windows NT 3.5 users.

AUTHOR

       fixnt   was   written   by   Holger   Bauer   <Holger.Bauer@topmail.de>,  Michael  Rath	<rath@itsm.uni-stuttgart.de>,  and  Akim  Demaille
       <demaille@inf.enst.fr>.

REPORTING BUGS

       Report bugs to the Authors, but avoid sending large postscript files.

       Patches are always welcome; send to <bauer@itsm.uni-stuttgart.de>.
