按日期将日志文件移动到存档文件夹，但不是每个进程的最后一个日志文件

Question

我有这些文件，[processName.DateTime.out]

/stev/log: ls -al

drwxrwxr-x    1 user.stev           user         4096 Feb  5 23:59 .

我的脚本将一些文件移动到存档文件夹，如果它在 7 天之前被修改。

sfind . -type f -mtime +7 -name "/stev/log" | while read FNAME
    do
        echo " moving file: " ${FNAME}      >> /stev/archive/archiveLog.log
        PCMD="mv ${FNAME} /stev/archive}"
        echo "PCMD=${PCMD}"                 >> /stev/archive/archiveLog.log
        eval "${PCMD}"                      >> /stev/archive/archiveLog.log
        echo ""                             >> /stev/archive/archiveLog.log
    done

此脚本将在下面列出文件，然后将它们移动到存档文件夹 [当前日期：2 月 5 日]

-rw-rw-r--    1 user.stev           user         4096 Jan 21 23:59 AAA01.202002010000.out
-rw-rw-r--    1 user.stev           user         4096 Jan 22 23:59 AAA01.202002020000.out
-rw-rw-r--    1 user.stev           user         4096 Jan 23 23:59 AAA01.202002030000.out
-rw-rw-r--    1 user.stev           user         4096 Jan 21 23:59 TEST03.202002010000.out
-rw-rw-r--    1 user.stev           user         4096 Jan 22 23:59 TEST03.202002020000.out
-rw-rw-r--    1 user.stev           user         4096 Jan 23 23:59 TEST03.202002030000.out

但问题是，我必须保留每个进程的最后一个文件。

例如）我可以移动下面的文件

-rw-rw-r--    1 user.stev           user         4096 Jan 21 23:59 AAA01.202002010000.out
-rw-rw-r--    1 user.stev           user         4096 Jan 22 23:59 AAA01.202002020000.out
-rw-rw-r--    1 user.stev           user         4096 Jan 21 23:59 TEST03.202002010000.out
-rw-rw-r--    1 user.stev           user         4096 Jan 22 23:59 TEST03.202002020000.out

但我应该保留下面的文件（不管多少天前，因为每个进程的最后一个文件都必须保留。）

-rw-rw-r--    1 user.stev           user         4096 Jan 23 23:59 AAA01.202002030000.out
-rw-rw-r--    1 user.stev           user         4096 Jan 23 23:59 TEST03.202002030000.out

这个问题有什么好办法吗？？

Answer 1

bash 和 "streams" 一样思考 - 有进有出。

# find all files
find /stev/log -type f -mtime +7 |
# extract the part before dot
cut -d. -f1 |
# for each process
# could be transformed into `xargs sh -c '...' --` for speed
while IFS= read -r process; do
    # all files with this process
    find /stev/log -type f -mtime +7 -name "$process*" |
    # sort numerically second field behind dot
    sort -t. -n -k2 |
    # remove last file, because we don't want to move it
    # maybe you need to remove first line, then just sort -r, check it
    head -n -1
done |
# mv each file into /stev/archive
xargs -d$'\n' -I{} mv -v {} "/stev/archive" >> /stev/archive/archiveLog.log

将 -t 选项传递给 xargs 进行调试。

按日期将日志文件移动到存档文件夹，但不是每个进程的最后一个日志文件

Move log files to archive folder by date, but not the last log file for each process

shell

archive
