Line endings are converted to \r\n

[TehPeGaSuS]

Ive uploaded a file (raw file here) to https://bpa.st/.

It's a Bash script and I even choose Bash from the programming language selector.

Since I've made it on Linux with nano it has LF as line ending.

But, when I do wget https://bpa.st/raw/6V5Q it is saved with CRLF as line endings like if it was made on Windows, which breaks the script entirely.

Example:

vitor@EliteDesk:~/Testing$ file userip.sh 
userip.sh: Bourne-Again shell script, ASCII text executable
vitor@EliteDesk:~/Testing$ wget https://bpa.st/raw/6V5Q

vitor@EliteDesk:~/Testing$ file 6V5Q 
6V5Q: ASCII text, with CRLF line terminators

If I try to run the script that I just wget'd:

vitor@EliteDesk:~/Testing$ bash 6V5Q 
6V5Q: line 1: !/usr/bin/env: No such file or directory

However, I've uploaded it to Debian pastebin (raw file here) and I use wget https://paste.debian.net/plain/1309920 it is saved with LF line endings.

I assume that the issue comes from pinnwand itself?

[supakeen]

I would assume the same. It seems the data is already stored with CRLF line endings in the database as requesting the hex view shows the \0d\0a bytes directly.

Yeah, I've probably mispasted it
