このシェルスクリプトで引数をどのように使用できますか？

誰もが次のスクリプトにパラメータを渡す方法を教えてもらえますか？

スクリプト作成者は、別のハードドライブ（sdb）のディレクトリパスを入力して引数を受け入れることを指定します。

頑張りました。./script/dev/sdbそして./scripts/media/users/data/testsどちらも失敗しました。修正する以下にエラーメッセージがあります。

#!/bin/bash

WRITEZERO=0 #Set whether to write zeroes or randoms to testfile (random is the default for both fio and crystaldiskmark); dd benchmarks typically only write zeroes which is why there can be a speed difference.

答え1

$TARGET（ファイルシステム）をテストするとfio機能します。変数エラーはヘッダーと結果情報にのみ影響します。

readlink&lsblkもシステムにあると仮定すると、 、および次の項目に置き換える方がDRIVE=うまく機能します（rawおよび仮想デバイスとパーティションを使用）。DRIVEMODEL=DRIVESIZE=

DEVICE=$(readlink -e /sys/dev/block/$(lsblk -npo MAJ:MIN $(df $TARGET 2> /dev/null | grep ^/dev | awk '{print $1}') | awk '{print $1}'))
if [ ! -f ${DEVICE}/dev ]; then
    echo "error determining device of $TARGET"
    exit 1
fi

DRIVE=$(echo $DEVICE | awk -F\/ '{print $NF}')

if [ -f ${DEVICE}/device/model ]; then
    DRIVEMODEL=$(cat ${DEVICE}/device/model)
else
    if [ -f ${DEVICE}/partition ]; then
        if [ -f ${DEVICE}/../device/model ]; then
            DRIVEMODEL=" $(cat ${DEVICE}/../device/model) (partition)"
        else
            DRIVEMODEL="partition"
        fi
    else
       if [ -d ${DEVICE}/dm ]; then
           DRIVEMODEL="virtual"
       else
           DRIVEMODEL="unknown"
       fi
    fi
fi

if [ -f ${DEVICE}/size ]; then
    DRIVESIZE=$(cat ${DEVICE}/size)
else
    DRIVESIZE=0
fi
DRIVESIZE=$(($DRIVESIZE*512/1024/1024/1024))GB
