In the second line , I have hardcoded the tab and I can see the results in TEMP2.txt . Ideally , if the solution worked , then TEMP1.txt and TEMP2.txt should have the same data and structure
In your script, rsuffix is empty, and so I don't expect it to output a <TAB> char. Try to assign sth. to it first, like rsuffix="\t" if your awk allows for that.

Also, the \t\t that you have hardcoded will be parameterized in my case. Can I replace \t\t using a parameter that I will be passing through command line?
man awk yields:
Code:
       ORS         The output record separator, by default a newline.

Code:
#!/bin/ksh
ors='\t\t\n'

awk '$0=$0' ORS="${ors}" TESTDATA.txt > TEMP2.txt

Thanks vgersh99 .. It worked ... Thanks a lot ..

Need another help. Is there a way to replace the delimiter of a file to tab ? The existing delimiter is pipe(|).

The type of delimiter i.e. tab or colon or semi-colon will be passed as an argument.

I am able to replace all but not the tab.

@neutronscott : Thanks for your solution. It worked.
@vgersh99 : Its not working. May be because you are not mentioning the existing fileseperator in the script
