I have been fiddling with this code for a few days. Mind you I am a beginner. I just want to get my script to be able to download a remote file, and scan MineCraft plugins. I got the scan plugins to work, but I'm having two other issues. One, I can't get the mc_addplugin to work correctly, and I get a Unexpected EOF and unexpected end of document when running any other command besides mc_scanplugins or mc_start
bash: -c: line 0: unexpected EOF while looking for matching `"'
bash: -c: line 1: syntax error: unexpected end of file
Help would be so much appreciated! Thanks in advance.
