有人可以帮帮我吗？＆＃39; elif的＆＃39;意外但错误是在elif之后的行

Answer 1

else部分中间有一个then：

...
    echo "If nothing wrong, your Swap is 192MB and should active"
    sleep 0.8
    else   # <-- this needs to go *after* the last `elif` section
    echo "/cache partition: not enough space"
    sleep 0.8
elif [ "$dtc" -gt "163840" ]; then
...

Bash，语法错误：＆＃39; elif＆＃39; elif线后意外
