我发送了包含空间使用信息的电子邮件。
df -Ph | mailx -s "disk usage" mybox@company.com
但是当我阅读一封电子邮件时,它看起来像这样:
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 2.0G 372M 1.6G 20% /
tmpfs 32G 12G 20G 38% /dev/shm

/dev/mapper/sys-var 2.0G 291M 1.6G 16% /var

/dev/sdc1 916G 602G 268G 70% /mnt/backup
/dev/sdb2 516G 241G 250G 50% /oradata/ods
任何想法,我如何预先格式化它以对齐表格中的列?
我希望它的格式很好:
