"List Index out of range" error when using xargs? #118

Copy link

I put together a list of links in Notepad and wanted to use anime-dl from WSL2 running Debian to run through the links I picked.

$ xargs -a links.txt -d "\n" -L 1 anime dl
anime: anime-downloader 4.5.0
anime: Extracting episode info from page
ERROR: list index out of range

If I copy/paste the link and write the command in myself ($ anime dl "...") it works. But weirdly, not here.

I had tried to use a script previously but, same result:

#!/bin/bash
if [ "x$1" = "x" ]; then
  echo "$0 <link list>";
  exit 1;
fi

if [ ! -f "$1" ]; then
  echo "$1: File not found.";
  exit 1;
fi

for i in $(cat $1); do
  echo "URL: $i"
  anime dl "$i"
done

I am a bit confused... Ideas? o.o

Looks like I was confused in the wrong place. This seems to be a nineanime issue - nothing more or less. Please close, if my estimate is right: 9anime doesn't like me flooding them with requests through a shell script. ^^;

EDIT: Invoking the program from the shell directly and passing the url directly too, this issue no longer occurs. Also, it seems that the last line of the text file also passes.

Issue found. I might update the script later - but really, the issue is so silly, I forgot it was a thing. So, Microsoft Notepad saves using CRLF line endings - but my script blatantly expected LF - and a random CR character was always passed at the end of the url.

# The list of urls:
https://...\r\n
# Then in the loop:
$i = https://...\r\n
# In the command:
anime dl $i\r

Solution will be to sed for CRLF alltogether. I just used dos2unix because I was lazy for now but...that was why.
