当共享/HD 达到全部容量的 95% 时，从文件夹中删除最旧的文件夹 + 文件 (50GB)

我有一个很大的共享（~5TB）即将满。现在我想制作一个脚本来删除 2 个指定文件夹中的数据。但这需要是最旧的文件/文件夹，并且需要在删除约 50GB 时停止，因此它不会删除所有文件夹。

编辑：这需要与我的 Synology DS-409 的 Samba 共享配合使用。该脚本需要在 Synology 的 /etc/crontab 中运行。

他们在其他地方给了我这个代码：

    #!/opt/bin/bash
dir=/data/video
min_dirs=3
full=60
logfile=/var/tmp/removed.log

df=`df | grep data | awk '{print $5}' | sed s/%//g`
if [ $df -gt $full ]; then
   [[ $(find "$dir" -type d | wc -l) -ge $min_dirs ]] &&
   IFS= read -r -d $'\0' line < <(find "$dir" -printf '%T@ %p\0' 2>/dev/null | sort -z -n)
   file="${line#* }"
   ls -lLd "$file"
   #rm -rf "$file"
   date=`date`
   if [ -f "$file" ]; then
      echo "$date $file could not be removed!" >> $logfile
   else
      echo "$date $file removed" >> $logfile
   fi   
fi

答案1

这应该有效：

DIRS="a/ b/"
MAXDELBYTES="53687091200" # 50GB
DELBYTES="0"

find $DIRS -type f -printf "%T@ %s %p\n" | sort -r -n | while read time bytes filename
do
    rm -fv "$filename"
    DELBYTES=$((DELBYTES + bytes))

    if [ $DELBYTES -ge $MAXDELBYTES ]; then break; fi
done

scai, autodelete.txt 是我在 Windows 中创建的文件并上传到 Linux 共享:) 现在由于 Windows Linux 代码问题，我在 Nano 中编写了此代码。

但现在它给出了一堆错误

root ~/.config # sh autodelete
find: unrecognized: -printf
BusyBox v1.20.2 (2012-08-09 05:49:15 CEST) multi-call binary.

Usage: find [PATH]... [OPTIONS] [ACTIONS]

Search for files and perform actions on them.
First failed action stops processing of current file.
Defaults: PATH is current directory, action is '-print'

        -follow         Follow symlinks

Actions:
        ! ACT           Invert ACT's success/failure
        ACT1 [-a] ACT2  If ACT1 fails, stop, else do ACT2
        ACT1 -o ACT2    If ACT1 succeeds, stop, else do ACT2
                        Note: -a has higher priority than -o
        -name PATTERN   Match file name (w/o directory name) to PATTERN
        -iname PATTERN  Case insensitive -name
        -path PATTERN   Match path to PATTERN
        -ipath PATTERN  Case insensitive -path
        -type X         File type is X (one of: f,d,l,b,c,...)
        -links N        Number of links is greater than (+N), less than (-N),
                        or exactly N
If none of the following actions is specified, -print is assumed
        -print          Print file name
        -exec CMD ARG ; Run CMD with all instances of {} replaced by
                        file name. Fails if CMD exits with nonzero

autodelete: line 11: bytes: not found
