linux – “echo”中的“ – – – ”是什么 – – – “ / sys / class / scsi_ho

我知道 linux命令

echo "- - -" > /sys/class/scsi_host/host0/scan

用于重新扫描scsi主机.但是“ – – – ”在命令中意味着什么？

解决方法

A quick google search出现this RHEL doc (and dozens of other answers)

This is the same command described in Section 7,“Adding a Storage Device or Path” to add a storage device or path. In this case,however,the channel number,SCSI target ID,and LUN values are replaced by wildcards. Any combination of identifiers and wildcards is allowed,allowing you to make the command as specific or broad as needed. This procedure will add LUNs,but not remove them.
