为什么我的 FTP 脚本无法使用 mget 命令获取所有文件？

我有一个脚本，它从不同的服务器提取数据，并从外部文件读取其详细信息。它读取文件，详细输出显示所有匹配的文件，但它仅从远程主机获取一个文件。以下是我的脚本：

while IFS=','; read region sdp ip1 ip2 ip3 user1 pass1 user2 pass2 user3 pass3
do

    in=/var/opt/fds/statistics/
    out=/pmautomation/PM/RawFiles/Data/BHCA/$date/$region/$sdp/
    file=\*"PSC-TrafficHandler_8.1_A_"\*"_System."$date\*".stat"

    mkdir -p /pmautomation/PM/RawFiles/Data/BHCA/$date/$region/$sdp/

    ftp -in $ip1<<END_SCRIPT
    quote USER $user1
    quote PASS $pass1
    bin
    prompt off
    lcd /pmautomation/PM/RawFiles/Data/BHCA/$date/$region/$sdp/
    cd /var/opt/fds/statistics/
    binary
    mget *PSC-TrafficHandler_8.1_A_*_System.$date*.stat
    bye
    END_SCRIPT

done < /root/SDP_BHC/bin/Credentials.csv

以下是输出：

为什么我的 mget 命令无法获取所有文件并且只能从所有匹配文件中获取一个文件？

答案1

我从杰夫那里得到了一些指示。不知何故，提示关闭不起作用，我收到提示以获取匹配的文件。我尝试将“y”放在mget命令下方并且它有效。以下是更新后的代码：

while IFS=','; read region sdp ip1 ip2 ip3 user1 pass1 user2 pass2 user3 pass3
do

    in=/var/opt/fds/statistics/
    out=/pmautomation/PM/RawFiles/Data/BHCA/$date/$region/$sdp/
    file=\*"PSC-TrafficHandler_8.1_A_"\*"_System."$date\*".stat"

    mkdir -p /pmautomation/PM/RawFiles/Data/BHCA/$date/$region/$sdp/

    ftp -in $ip1<<END_SCRIPT
    quote USER $user1
    quote PASS $pass1
    bin
    prompt off
    lcd /pmautomation/PM/RawFiles/Data/BHCA/$date/$region/$sdp/
    cd /var/opt/fds/statistics/
    binary
    mget *PSC-TrafficHandler_8.1_A_*_System.$date*.stat
    y
    y
    y
    y
    bye
    END_SCRIPT

done < /root/SDP_BHC/bin/Credentials.csv

这确实是很奇怪的行为，但它对我有用。幸运的是，我知道远程主机中的文件数量，并输入相同数量的“y”使其工作。

您是否尝试过从“此处”文档末尾删除选项卡？由于脚本没有检测到结束，这可能是您的问题。

while IFS=','; read region sdp ip1 ip2 ip3 user1 pass1 user2 pass2 user3 pass3
do

    in=/var/opt/fds/statistics/
    out=/pmautomation/PM/RawFiles/Data/BHCA/$date/$region/$sdp/
    file=\*"PSC-TrafficHandler_8.1_A_"\*"_System."$date\*".stat"

    mkdir -p /pmautomation/PM/RawFiles/Data/BHCA/$date/$region/$sdp/

    ftp -in $ip1<<END_SCRIPT
    quote USER $user1
    quote PASS $pass1
    bin
    prompt off
    lcd /pmautomation/PM/RawFiles/Data/BHCA/$date/$region/$sdp/
    cd /var/opt/fds/statistics/
    binary
    mget *PSC-TrafficHandler_8.1_A_*_System.$date*.stat
    bye
END_SCRIPT    <----------

done < /root/SDP_BHC/bin/Credentials.csv

使用wget。

while IFS=','; read region sdp ip1 ip2 ip3 user1 pass1 user2 pass2 user3 pass3
do
    in=/var/opt/fds/statistics/
    out=/pmautomation/PM/RawFiles/Data/BHCA/$date/$region/$sdp/
    file=\*"PSC-TrafficHandler_8.1_A_"\*"_System."$date\*".stat"

    mkdir -p $out
    cd $out

    wget --ftp-user=$user1 --ftp-password=$pass1 ftp://$ip1/$in/$file

done < /root/SDP_BHC/bin/Credentials.csv
