Hi Robin ,

Here is the actual requirement.. There are files generated for current year and next year in a particular folder , I need to concatenate these two files into a total year file ,

For example ABC_NYFWFX.txt and ABC_CYFWFX.txt , these two files indicate next year and current year , FWFX indicate forecast fx rates .

Yes there are fixed set of files , I am really new to unix , I have perl and shell scripting ,I just tried using cat to concatenate these , but I want to do using loop ,I hope the code given by you works ,Not tested though, Thanks Much

Regards,
DJ
