How to modify the script to include cat function
I have the following script that greps lines containing "AT" from data files data1.hsq through data1000.hsq, then cuts their second column and puts in data files called perm1 through perm1000.

I want to modify the script so that instead of putting the data in separate data files perm1 through perm1000, it concatenates them into a single data file. So essentially the same effect as using cat to concatenate perm1 through perm1000. How do I go about doing that? Thanks!

Code:
for i in {1..1000}
do
grep "AT"  data$i.hsq | cut -f2 > perm$i
done

source(n)						       Tcl Built-In Commands							 source(n)

__________________________________________________________________________________________________________________________________________________

NAME

       source - Evaluate a file or resource as a Tcl script

SYNOPSIS

       source fileName

       source -rsrc resourceName ?fileName?

       source -rsrcid resourceId ?fileName?
_________________________________________________________________

DESCRIPTION

       This  command takes the contents of the specified file or resource and passes it to the Tcl interpreter as a text script.  The return value
       from source is the return value of the last command executed in the script.  If an error occurs in evaluating the contents  of  the  script
       then  the source command will return that error.  If a return command is invoked from within the script then the remainder of the file will
       be skipped and the source command will return normally with the result from the return command.

       The end-of-file character for files is '32' (^Z) for all platforms.  The source command will  read  files  up  to  this  character.   This |
       restriction  does  not  exist for the read or gets commands, allowing for files containing code and data segments (scripted documents).	If |
       you require a ``^Z'' in code for string comparison, you can use ``32'' or ``u001a'', which will be safely substituted by the Tcl  inter- |
       preter into ``^Z''.

       The -rsrc and -rsrcid forms of this command are only available on Macintosh computers.  These versions of the command allow you to source a
       script from a TEXT resource.  You may specify what TEXT resource to source by either name or id.  By default Tcl searches all open resource
       files,  which  include  the  current  application  and any loaded C extensions.	Alternatively, you may specify the fileName where the TEXT
       resource can be found.
