text manipulation script
 

Hey programming brains,

I am lokin a script that can take a text file as input and add 0000 at the beginning of each line in that file.

it can be in any lang like shell script or c script

You could use:

nice input , I checked and found only 1st line (beginning of file) is added with 0000 and nowhere else . It's windows text file I copied in linux seems vi editor considering all text file as 1 line.

is thr any method I can convert a text file as linewise(new line) after every 100 characters .

Windows files use a different kind of line break code from Unix ones. You'll have to convert it before most *nix tools will work properly. There are a multitude of ways to do this, including opening it up in one of the common text editors like kwrite or gedit and resaving it with the unix setting, or using a command-line application like flip.

or use dos2unix

Then add a g for global in the sycamorex's solution:
if you want to edit the file in place, use the -i option. -i.bck makes a backup copy of the original file adding the .bck extension (you can use any extension of your choice).
