Bash脚本不会ssh csv文件的所有条目 [英] Bash script does not ssh all the entries of a csv file

问题描述

我正在尝试使用最新的修订包修补大量CENT OS计算机.我有以下bash脚本，它将csv文件作为输入，其中包含这些计算机的IP地址和密码.

I am trying to patch a bunch of CENT OS machines with the latest fix pack. I have the below bash script that takes csv file as a input which has the ip address and password for those machines.

该代码运行良好，但是，它仅适用于第一行，而对于其余列表似乎不起作用，因为我的output.txt仅具有适用于第一行主机的条目.

The code works fine however, it would only work for the first row it does not seem to be working for the rest of the list as my output.txt only has the entry only for the first row host .

patch.sh

INPUT=hosts_test.cvs
OLDIFS=$IFS
IFS=,
[ ! -f $INPUT ] && { echo "$INPUT file not found"; exit 99; }
while read privateip password
do

sshpass -p$password ssh -t -o "StrictHostKeyChecking no" user123@$privateip "

hostname
hostname -I --all-ip-addresses
sudo yum -y update bash
env x='() { :;}; echo vulnerable' bash -c \"echo If you see the word vulnerable above, then you are vulnerable to shellshock\"
echo ""
exit

" >> output.txt

done < $INPUT
IFS=$OLDIFS

hosts_test.cvs

hosts_test.cvs

10.xxx.xx.219,abcd~qY1
10.xxx.xx.226,l4~abcdefg
10.xxx.xx.221,l4@abcdefgh

端子输出

由于stdin不是终端，因此不会分配伪终端.

Pseudo-terminal will not be allocated because stdin is not a terminal.

推荐答案

在sshpass命令</dev/null的末尾添加.

Add at the end of your sshpass command </dev/null.
