Question

我想在远程服务器2上创建许多已存在于server1上的目录。我在server1上的脚本：

LOG_DIR="/opt/server1/service/logs/"
DEST_HOST="server2"
DEST_USER="logger"
DEST_DIR="/volumes/storage/server1"

LISTEN_DIR=$(find $LOG_DIR -type d | tr '\n' ' ')

ssh $DEST_USER@$DEST_HOST " for Y in $LISTEN_DIR
                do
                    if [ ! -d  $DEST_DIR$Y ]; then
                        mkdir -p $DEST_DIR$Y;
                    fi
                done"

但是在目录/ opt / server1 / service / logs /的server1上还有其他几个目录...... 脚本结果：

[20:00 root@server1:~]# bash -x script.sh
+ LOG_DIR=/opt/server1/service/logs/
+ DEST_HOST=server2
+ DEST_USER=logger
+ DEST_DIR=/volumes/storage/server1
++ find /opt/server1/service/logs/ -type d
++ tr '\n' ' '

Answer 1

尝试这样做：

find local_dir -type d -print0 |
ssh remote 'while IFS="" read -r -d "" a; do mkdir -p "remote_dir/$a"; done'

或者如果你喜欢单行：

find local_dir -type d -print0 | ssh remote 'while IFS="" read -r -d "" a; do mkdir -p "remote_dir/$a"; done'

说明

find local_dir -type d：从local_dir打印所有目录，以便STDOUT
|：Unix pipe：将STDOUT的最新命令分支STDIN
ssh remote 'remote_command'：ssh到远程服务器，然后执行命令。需要单'个引号来阻止shell插入$a变量
while read a; do mkdir -p remote_dir/$a; done：远程命令，它在STDIN
mkdir -p，无需检查任何目录的存在

bash创建许多目录，如果它不存在于ssh上
