Удалите самые старые папки + файлы (50 ГБ) от папки, когда доля/HD достигнет 95%-й полной мощности

Это должно работать:

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 является файлом, который я создал в окнах и загрузил на долю Linux :) Теперь я сделал этот код в нано из-за окон проблемами кода Linux.

Но теперь это дает набор ошибки

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.

        -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

        -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
