#无法匹配$,还不知道怎么解决

上边是ssh的自动登录,可以配合下边的shell使用,很方便。
文件名:xxx_launcher
代码如下:
#!/bin/sh
##
# 服务器登陆器
#
# @author zhiyuan <hzyhouzhiyuan@gmail.com>
##
channel_user="user_namexxx"
channel_passwd="xxxx"
#内网通道机
internal_ip1=xxx.xxx.xxx.xxx
#联通
unicom_ip1=xxx.xxx.xxx.xxx
#电信
telecom_ip1=xxx.xxx.xxx.xxx
case "$1" in
ci)
expect ssh_auto_login $channel_user $channel_passwd $internal_ip3 22
cl)
expect ssh_auto_login $channel_user $channel_passwd $unicom_ip1 22
cd)
expect ssh_auto_login $channel_user $channel_passwd $telecom_ip1 22
149)
expect ssh_auto_login channel_user channel_passwd xxx.xx.xxx.xxx 22
49)
expect ssh_auto_login $channel_user $channel_passwd $unicom_ip1 22 需要通道机跳转的ipxxx.xxx.xx

echo "帮助信息:"
echo "\tthere is not a server named [$1]"
echo "\t服务器149:\t149"
echo "\t服务器49:\t49"
esac
此时登陆某个服务器的时候就直接 用上述shell带要登录的服务器参数即可,如: ./xxx_launcher 49
