Change EOL (End Of Line) Character from Windows to Unix/Linux for all the files in current working directory

Hi all,

For a single file, you can do the change of EOL using notepad++.
Reference: http://psrdotcom.blogspot.in/2017/01/change-eol-end-of-line-character-from.html

But it would be difficult, if you want to do for multiple files in one go.

I have found a solution to update EOL for all files in the current directory.

Pre-requisite

Make sure that, working directory contains only the files which you want to change EOL.

Note: If not, copy the files to a new directory and change the EOL for all the files in that directory.

Procedure

1. Download dos2unix utility from sourceforge https://sourceforge.net/projects/dos2unix/
2. Extract the zip file
3. Tip: Make sure that the extracted path doesn't contain spaces.

5. Download the customized batch file from GIST https://gist.github.com/psrdotcom/d73ff9590c3010253b5b2a886704b26b
6. Extract if needed, and place the "dos2unixfolder.bat" in the same directory where the "dos2unix" is placed.
7. Tip: If you place the batch file in the same folder of dos2unix.exe. You no need to add again the patch of batch file in environment PATH.
8. Navigate to your folder, where you want all the files EOL to be changed
9. Press "Right Click on Mouse" in empty area
10. 
11. Select "Open Command Prompt Here"
12. Type the batch file name "dos2unixfolder.bat"
13. You will able to see the conversion process

Windows file name too long to delete move copy rename due to destination path too long

Hi friends,

Problem

When i am clearing my old windows folder from the OS installed drive, I had an issue of deleting the files and folder because the path name is too long.

The error message is

The file name(s) would be too long for the destination folder. You can shorten file name and try again, or try a location that has a shorter path."

Background

Solution

1. Navigate to the folder in the windows explorer
2. Type the following command in the address bar and hit enter key
• subst j:
3. Open a new windows explorer window
4. Now you will be able to see new drive with letter J:
5. You will be able to delete the files/folders with in the drive
