我在运行我的脚本时遇到 cluster_network_operations.sh:第44行:[:0:二元运算符预期错误
在我的脚本中,我正在调用 ssh-copy-id 命令,然后根据其输出设置返回码。
ssh-copy-id:output
WARNING: All keys were skipped because they already exist on the remote system.
Successful:
Number of key(s) added: 1
Now try logging into the machine, with "ssh 'bhupesh@10.236.61.133'", and check in:
2. All keys were skipped because they already exist on the remote system
我使用了一个函数contains来检查字符串中的子字符串。下面的代码段,
contains() {
# check if the substring exits in a string.
string="$1"
substring="$2"
if test "${string#*$substring}" != "$string"
then
return 0 # $substring is in $string
else
return 1 # $substring is not in $string
fi
}
enable_auth(){
# Enabling the authentication by sending the pub_key of all the nodes in
# the cluster to the new gateway.
# Currently, its a one way secure authentication.
#pdsh -S -g all -N cat /root/.ssh/id_rsa.pub | ssh "$2"@"$1" 'cat >> .ssh/authorized_keys'
ssh-copy-id -i ~/.ssh/id_rsa.pub "$2"@"$1"
ret=$?
#sub_str = "Now try logging into the machine, with"
if [ contains "$ret" "Now try logging into the machine, with" ]
then
echo "Successfully Configured"
ret=0
elif [ contains "$ret" "All keys were skipped because they already exist on the remote system" ]
then
echo "System "$1" is already configured for the user: $2"
ret=0
else
ret=1
fi
echo 0
}
答案 0 :(得分:0)
返回代码0表示成功或为真,<> 0表示错误
退出状态的使用示例
function fncInitialize() {
var objDate = $(this).find("input[data-datepicker='True']");
objDate.datepicker();
fncBindControls();
}
function fncBindControls() {
}
