bash脚本的if和else语句

Question

我正在为bash脚本编写if和else语句。

但是某些原因表明找不到命令。那么，我该怎么解决？

代码如下：

 echo "Please choose the following option: "
 echo "1: Make an New Folder"
 echo "1: Remove a Folder"
 echo -n "Enter the number: "
 read x

 if [$x -eq 1]: **command not found**
 then
   echo -n "Please Enter the New Folder Name"
   read New_Folder
   mkdir $New_Folder

 elif [$x -eq 2]: **command not found**
 then
   echo -n "Enter the Folder Name that you like to remove from the list: "
   read Remove_Folder
   rm-f $Remove_Folder
 fi
