使用 VIM 编辑器打开文件时出现警告

Question

我正在运行 shell 脚本来生成我将用来运行我的程序的主机。 相同的代码如下。

#!/bin/bash

rm hosts > /dev/null 2>&1
touch hosts
hosts=()
count=0
for i in $(seq 22 1 54)
do
    var=$(ssh csews$i uptime | grep -o 'load' | wc -w)
    if [ $var -eq 1 ]
    then
        hosts+=("csews$i")
        echo "csews$i:8" >> hosts
        count=$((count+1))
    
        if [ $count == 8 ]
        then
            break
        fi
    fi
done

我正在使用bash filename.sh进行相同的编译

但是每当我尝试打开主机文件时，使用此命令vim hosts我都会收到此消息

E325: ATTENTION

      NEWER than swap file!

(1) Another program may be editing the same file.  If this is the case,
    be careful not to end up with two different instances of the same
    file when making changes.  Quit, or continue with caution.
(2) An edit session for this file crashed.
    If this is the case, use ":recover" or "vim -r hosts"
    to recover the changes (see ":help recovery").
    If you did this already, delete the swap file ".hosts.swp"
    to avoid this message.

Swap file ".hosts.swp" already exists!

导致此错误的我的 shell 脚本有什么问题？
