无法进行修改以适应我的环境，这是 check_disc 功能，但在通过 /dev/mapper/ 附加磁盘的环境中无法正常工作，所以我有例如 /dev/mapper/debian-var 而不是 /var .

BASH 脚本中的函数：

function check_disks {

    THOLD=$1;
    DISK_ERROR="";

    # df -kl is the most portable options for df 

    MOUNTS=`df -lk | grep -v devfs | grep -v none | grep -v Filesystem | awk '{print $6}'`;
    for MOUNT in $MOUNTS; do
        PERCENT=`df -kl $MOUNT | grep -v Filesystem | awk '{print $5}' | sed 's/\%//'`;
        if [ $PERCENT -gt $THOLD ]; then
            DISK_ERROR="$DISK_ERROR    Volume '$MOUNT' is at $PERCENT% usage.\n";
        fi
    done
    if [ -n "$DISK_ERROR" ]; then
        echo -en "ERROR: The following volumes have exceeded the allowable threshold of $THOLD% usage.\n$DISK_ERROR";
        return 1;
    else
        return 0;
    fi

}

df -kl cmd 的输出：

df -kl

                       1919048    493616   1327948  28% /

                     377857560 183429768 175233732  52% /var

我猜这条线应该改变：

MOUNTS=`df -lk | grep -v devfs | grep -v none | grep -v Filesystem | awk '{print $6}'`;

但不确定如何。任何人都可以帮我一把吗？谢谢

有一个可移植性选项df，可将输出保持在每卷一行：

   -P, --portability
          use the POSIX output format

我认为改变

MOUNTS=`df -lk | grep -v devfs | grep -v none | grep -v Filesystem | awk '{print $6}'`

到

MOUNTS=`df -lkP | grep -v devfs | grep -v none | grep -v Filesystem | awk '{print $6}'`

有助于。

仅供参考，这是输出差异的示例：

$ df -lk | grep -B1 /var
/dev/mapper/rootvg-var
                   4062912   1900724   1952476  50% /var
$ df -lkP | grep /var
/dev/mapper/rootvg-var   4062912   1900748   1952452      50% /var
