Linux"丢失"错误

Question

我想写一个.sh但是得到一个错误:
这是一个minecraftserver更新程序(仅供参考)

码:

#!/bin/sh

# Deleting Old Files
if [ -e spigot1.jar]; then
  rm spigot1.jar

fi

# Renaming
if [ -e spigot.jar]; then
  echo Renaming File...
  mv spigot.jar spigot1.jar
  echo Done.
  echo
  else
  echo

fi

# Downloading
echo Downloading File...
wget http://ci.md-5.net/job/Spigot/lastBuild/artifact/Spigot-Server/target/spigot.jar
echo Done.

# Comparing Files
echo
echo Testing if the files are the same... 
if diff -a -w spigot.jar spigot1.jar >/dev/null ; then
  echo Done.
  echo
  echo -----------------------------------
  echo
  echo You already have the newest version!  
  echo
  echo -----------------------------------
else
  echo Done.
  echo
  echo -----------------------------------
  echo
  echo Updated to a newer version! 
  echo
  echo -----------------------------------

fi

if [ -e spigot1.jar]; then
  rm spigot1.jar

fi

sleep 10s

但它弹出一条错误信息说:

test.sh: 4: [: missing ]
test.sh: 12: [: missing ]

有没有办法来解决这个问题？在修复之前我无法继续下去!提前谢谢

你需要空间

if [ -e spigot1.jar ]; then

代替

if [ -e spigot1.jar]; then
