从不同目录中匹配的子目录下载所有csv文件

Question

每个月的第一天，我需要连接到SFTP服务器，并根据上个月从某些子目录下载所有csv文件。

要连接到的示例文件目录

sftp_url/csv/client1.1/10/
sftp_url/csv/client1.2/10/
sftp_url/csv/client1.3/10/
sftp_url/csv/client1.4/10/
sftp_url/csv/client2.1/10/
sftp_url/csv/client2.2/10/
sftp_url/csv/client2.3/10/
sftp_url/csv/client2.4/10/

子目录中的"10"表示月份，因此是"十月"。在/10/子目录中有多个csv文件，我需要将它们全部下载。

• 我已经找到了用lftp连接到SFTP服务器的代码
• 我有代码来确定"10"，它是date -d "last month" +"%m"

但是，我还没有找到如何定义我只想访问上个月文件夹==值所在的所有目录，而不列出所有完整的文件路径。

有人能确认是否有一个简单的命令允许这种事情吗？如果这是非常直接的事情，请道歉。我是新来的命令行，这是一个陡峭的曲线。感谢您提供的任何帮助和反馈。

#!/bin/sh
set -eu
SFTP_SERVER="sftp.location.com"
SFTP_USER="user"
SFTP_DIR="/csv"
DEST=$(basename $SFTP_DIR) ## defines directory based on where my current directory is and the sftp folder name
mkdir -p "$DEST" ## makes new directory based on basename and the month found in the downloaded folder
lftp sftp://$SFTP_USER@$SFTP_SERVER:$SFTP_DIR/ -e "lcd '$DEST'; mirror; bye"
ACCT_BREAKDOWNS=$(find "$DEST" -mindepth 1 -maxdepth 1 -type d) ## defines the month folders based on going 1 folder in from the sftp folder name
YEAR=$(TZ=UTC-24 date +%Y -d "-1 month") ## defines the year for the folders created, ensuring that it creates a new folder when we enter the new year
for ACCT_BREAKDOWN in $ACCT_BREAKDOWNS; do
ACCT=$(basename "$ACCT_BREAKDOWN" | sed -E -e 's/_(.2|.1|.3)$//') ## strips folders to just show client name
DATES=$(find "$ACCT_BREAKDOWN" -mindepth 1 -maxdepth 1 -type d -printf "%fn") ## prints out a list of client names, with a separate one for each line
#DATES="09 10" ## would be used to specify clear dates
for DATE in $DATES; do
mkdir -p "account/$ACCT/$YEAR-$DATE" ##create directory based on the client name after filename is stripped)
for FILE in $(find "$ACCT_BREAKDOWN/$DATE" -type f); do ##  works on files that are in the sftp folder and date sub folder.
ln -f -t "account/$ACCT/$YEAR-$DATE" "$FILE" ## creates a hard link between the csv folder and account folder, placing files in a folder that match their client name and the right month.
done
done
done
rclone sync account/ remote:folder/folder ## syncs folder layout to gdrive
TODAY=$(date)
echo "$TODAY    global  script" > ~/error-log/log/log.tsv ## creates a tsv which is used a reference to what failed on my cronjobs
exit
