Linux下shell调用expect进行批量升级
执行main.sh脚本即可实现无手执对hostname中各IP机器进行updatefilename升级包的升级。tcl和expect压缩包放在相同路径下，$TSMIS_ROOT为环境变量。
CopyFile.exp文件：
#!/usr/bin/expect -f
#输入分析仪ip以及需要上传的文件名和TSMIS_ROOT环境变量
set ip [lindex $argv 0]
set localfile [lindex $argv 1]
set TSMIS_ROOT [lindex $argv 2]
#scp拷贝需要传输的文件到指定目录，并且跳过手动输入部分
spawn scp -r $localfile root@$ip:$TSMIS_ROOT/tmp/$localfile
set timeout 300
expect {
"yes/no" {send "yes\r" ; exp_continue}
"*assword:" {send "111111\n"}
}
set timeout 300
send "exit\r"
expect eof
RunUpdate.exp文件：
#!/usr/bin/expect -f
set ip [lindex $argv 0]
set updatefile [lindex $argv 1]
set TSMIS_ROOT [lindex $argv 2]
spawn ssh root@$ip
set timeout 300
expect "*assword:" { send "111111\n" }
set timeout 300
expect "#"
send "cd $TSMIS_ROOT/tmp\r"
set timeout 300
expect "#"
send "tar -zxvf $updatefile.tar.gz\r"
set timeout 300
expect "#"
send "cd $updatefile\r"
set timeout 300
expect "#"
send "sh $TSMIS_ROOT/bin/mykillproc.sh\r"
set timeout 300
expect "#"
send "sh *pdate.sh\r"
set timeout 300
expect "#"
send "reboot\r"
set timeout 300
expect "#"
send "exit\r"
expect eof
main.sh文件：
#Input TS/VAR IP into ' ',use "," to seperate them. Ex: hostlist:'192.168.10.178,192.168.10.179,192.168.10.180'
