Hmm
If you are looking at speed then C app will do the job. As far as ^M ..... it meant enter key. So your data file is from Windows/DOS? or what? They can be removed with sed:
I can add few more commands...

No actually the data is provided as library data which is meant for viewing only. Dont think it is from DOS

would be glad to see few more commands monk.
thanx a lot for i have been learning shell script more by experimenting.......

also,
what if i want some lines deleted. From those 193 lines of data, i might have to delete some selected lines based on column one data ( which we have erased from the original data) in all the .txt files. I know that i have to write a new file say test.sed in which i write down all patterns which i want to be modified and then use
$ sed -f test.sed INPUTFILE.TXT
havent understood much about the pattern finding and deleting whole line from file!
once all the .txt files are modified ( we can also delete the first 27 line we can append all the column two data in a single final file and ofcourse remove the ^M from the files.
what do u advise?

How do i reverse the data order. right now output_file had data in descending order based on column one data. I want the last data to be at the beginning of file.

to put it simply, right now data in the output file is 14.232, 13.2332, 2.343, 6.89, .........10.23, 11.234.
But i would like the file to be 11.234, 10.23, .......6.89, 2.343, 13.2332, 14.232.
Havent thought much about it. Any ideas?
