在意外標記'do'附近出現unix bash語法錯誤

Question

我創建了一個unix minecraft啓動器。它在一個半小時前（截至9:30）完全正常工作。那麼我得到這個：

/home/axium1998/MinecraftMegaLauncher.sh: line 14: syntax error near unexpected token ~'$'do\r''. 
/home/Axium1998/MinecraftMegaLauncher.sh: line 14: 'do 

我不知道是什麼造成了這一點。

# If code needs to be changed, just send me a PM saying something like: Project:MinecraftMegaLauncher Line #<line number> = <changed code> 
# if it works (I bet it will, but for me to learn xP)it will be replaced/fixed.

編輯：可能不是確切的路線。我最後上傳它後，我改變它

我瘋狂的猜測是，你的腳本轉換爲Windows格式（也許從Windows複製它），然後你收到此錯誤：意外do\r，因爲\r是意外的。使用dos2unix將其轉換。
