Solaris 中的脚本在文件系统达到规定阈值时发送邮件 
#!/bin/bash
threshold="1"
{
        >/tmp/output
        for fs in $(df -hk | awk '{print $6}' | sed '1 d'); do
                chk=$(df -hk ${fs} | sed '1 d' | awk '{print $5}' | awk -F\% '{print $1}')
                if [ "${chk}" -gt "${threshold}" ]; then
                        echo "$(hostname): Alert Fileystem ${fs} is above ${threshold}%." >>/tmp/output
                fi
        done
        cat /tmp/output| mailx -s "sub" [email protected]
}

现在，如果 fs 超过阈值限制，我们应该收到邮件

只是建议您如何做到这一点。请参阅脚本中的注释。

#!/bin/bash

# define constants on top so you can find and edit them easily
declare -ri threshold=1
declare -r mailsubject="[$(hostname)] FS Alert Exceed ${threshold}%"
declare -r mailbodystart="$(hostname) Filesystem Alert, threshold=${threshold}%\n"
declare -r mailto="[email protected]"

# use variable instead of output file
declare mailbody=""

for fs in $(df -hk | awk '{print $6}' | sed '1d'); do
        chk=$(df -hk ${fs} | sed '1d' | awk '{print $5}' | awk -F\% '{print $1}')
        if [ "$chk" -gt "$threshold" ]; then
                # append to mailbody
                mailbody="${mailbody}${chk}% ${fs}\n"
        fi
done

# send mail if mailbody is non-empty
if [ -n "$mailbody" ]; then
        # sort by filesystem size, largest first
        mailbody=$(echo -e "$mailbody" | sort -nr)
        echo -e "${mailbodystart}${mailbody}" | mailx -s "$mailsubject" "$mailto"
fi
