.SH DESCRIPTION
.sp
This tool is part of the cifs\-utils suite.
.sp
\fIsmbinfo\fP is a userspace helper program for the Linux SMB
client file system (CIFS). It is intended to display SMB\-specific file
informations such as Security Descriptors and Quota.
.sp
This tool works by making an CIFS_QUERY_INFO IOCTL call to the Linux
SMB client which in turn issues a SMB Query Info request and returns
the result. This differs from \fIgetcifsacl\fP which uses extended file
attributes.
.SH OPTIONS

.SH NOTES
.sp
Kernel support for smbinfo utilities requires the CIFS_QUERY_INFO
IOCTL which was initially introduced in the 4.20 kernel and is only
implemented for mount points using SMB2 or above (see mount.cifs(8)
\fIvers\fP option).
