Removing trailer from a flat file!!!
Hi,
I get some flat files with trailer which gives the totol records count and i want to remove the trailer from the file.
i used the following command it works fine with a single file.
cat file_name | grep -v 'Total records:' > file1
mv file file_name
But i dont know how to remove the trailer when we have more than 1 file and how to redirect them and move them back to the original file name
The syntax of file is :
<date>.file_name.txt
something like 06222007.aaa_ddd_ccc_ddd.txt
06212007.aaa_ddd_ccc_ddd.txt
06202007.aaa_ddd_ccc_ddd.txt
Regards,
Kumar
