shell脚本中获取远程文件时出错

Question

我有这个脚本正在 4 台服务器上执行 scp 并在调用服务器上获取文件，但是当我运行它时，出现以下错误：

syntax error near unexpected token `then'
line 16: `if[[ $line = $texts ]] ; then 

代码如下：

#!/bin/sh
servers=("[email protected]" "[email protected]" "[email protected]" "[email protected]")
tlen=${#servers[@]}
count=o
total=0
texts="Untar done you can upload new .tar file"
for(( i=0; i<${tlen}; i++ ));
    do
    echo "in"
    scp ${servers[$i]}:/usr/site/html/test/test.txt /mnt/backups/updateimage
    cat test.txt ; while read line
    do
    echo "in"
    let count++
    echo "$line"
    if[[ $line = $texts ]] ; then 
    echo "true" 
    let total++ 
    else echo "false" 
    fi
   done < test.txt
done
exit 0

Answer 1

在 if 和 [[

编辑

之间添加一个空格我刚刚运行了此测试，它的正确计算结果为 false

#!/bin/bash

set -eu

texts="Untar done you can upload new .tar file"
line="foo"

if [[ $line = $texts ]] ; then
  echo "true"
else
  echo "false"
fi

我怀疑您的问题出在其他地方
