istat { FileName | i-nodeNumber Device }
The istat command displays the i-node information for a particular file. You can specify the file either by providing a file or directory name with the FileName parameter or by providing an i-node number with the i-nodeNumber parameter and a device name with the Device parameter. You can specify the Device parameter as either a device name or as a mounted file system name.
If you specify the FileName parameter, the istat command writes the following information about the file:
Note: The owner and group names for remote files are taken from the local /etc/passwd file.
If you specify the i-nodeNumber and Device parameters, the istat command also displays, in hexadecimal values, the block numbers recorded in the i-node.
Note: The Device parameter cannot refer to a remote device.
