我尝试通过ssh连接到远程服务器并执行命令。
但鉴于这种情况,我只能执行一个命令。
例如
ssh -i ~/auth/aws.pem ubuntu@server "echo 1"
效果很好,但我遇到以下问题
情形1
ssh -i ~/auth/aws.pem ubuntu@server "cd /"
ssh -i ~/auth/aws.pem ubuntu@server "ls"
情形2
ssh -i ~/auth/aws.pem ubuntu@server "export a=1"
ssh -i ~/auth/aws.pem ubuntu@server "echo $a"
会话未得到维护。
当然,您可以使用" cd /; LS" 但我一次只能执行一个命令。

开发了一个bash脚本
function cmd()
{
local command_delete="$@"
if [ -f /tmp/variables.current ]; then
set -a
source /tmp/variables.current
set +a
cd $PWD
fi
if [ ! -f /tmp/variables.before ]; then
comm -3 <(declare | sort) <(declare -f | sort) > /tmp/variables.before
fi
echo $command_delete > /tmp/export_command.sh
source /tmp/export_command.sh
comm -3 <(declare | sort) <(declare -f | sort) > /tmp/variables.after
diff /tmp/variables.before /tmp/variables.after \
| sed -ne 's/^> //p' \
| sed '/^OLDPWD/ d' \
| sed '/^PWD/ d' \
| sed '/^_/ d' \
| sed '/^PPID/ d' \
| sed '/^BASH/ d' \
| sed '/^SSH/ d' \
| sed '/^SHELLOPTS/ d' \
| sed '/^XDG_SESSION_ID/ d' \
| sed '/^FUNCNAME/ d' \
| sed '/^command_delete/ d' \
> /tmp/variables.current
echo "PWD=$(pwd)" >> /tmp/variables.current
}
ssh -i ~/auth/aws.pem ubuntu@server "cmd cd /"
ssh -i ~/auth/aws.pem ubuntu@server "cmd ls"
有什么更好的解决方案?

$ cat <<'EOF' | ssh user@server
export a=1
echo "${a}"
EOF
Pseudo-terminal will not be allocated because stdin is not a terminal.
user@server's password:
1
通过这种方式,您将所有命令作为单个文件脚本发送到ssh
,因此您可以输入任意数量的命令。请注意在单引号EOF
之间使用'
的方式。
