Question

我是编程的新手..我有这个sftp脚本，它sftp到其他服务器检查一些条件＆amp;然后得到文件。

#! /usr/bin/bash

while read line
do
#echo $line
if [[ $line =~ ^#  ]];
then
#echo $line;
continue;

else
serverIP=`echo $line|cut -d',' -f1`
userID=`echo $line|cut -d',' -f2`
fi
done < sftp.conf

cd /root

sshpass -p red32hat sftp $userID@$serverIP <<EOF
for (; ;) 
do
cd /root/perl
#foreach my $file (<$inputdir/*seq>) {
for $file in *seq 
do
abc1=`find $file -mmin +1`;
if [[ $abc1 eq "" ]] 
then
echo "Skipping file as of now as file is not completed \n";
continue;
fi
mget $file
done
sleep 30
done
bye
EOF

但是每次sftp步骤都会抛出错误，说“无效命令”..我猜一般shell命令在sftp中不起作用...请帮助...下面是错误信息...

Answer 1

在EOF中添加引号以防止在此文档中进行扩展：

sshpass -p red32hat sftp "$userID@$serverIP" <<'EOF'

将变量放在引号周围以防止分词和路径名扩展。

同样for $file in *seq应为for file in *seq。

for (; ;)也应为for ((;;))。

eq中的

[[ $abc1 eq "" ]]不是有效的运算符。也许您的意思是=或==。

shell命令在SFTP脚本中不起作用
