Append variable texts to the beginning of each line in all files in a directory
I am writing a code to append some numbers in the beginning of each line in all the files present in a directory. The number of files are really huge. The files are numbered as 1.sco, 2.sco, 4.sco (Note: 3.sco is missing).
The files currently look like this:
1.sco
My task is to open each 1.sco, 2.sco and so on and add a number based on its file name at the beginning of each line in all files. This is what I intend, sample output:
1.sco
2.sco
I have written a code but not getting where actually the problem is?
The first line is a loop which generates the numbers. Then second lines tests for the presence of file and third line adds a text in the beginning of each line. I am using Linux with BASH.
