.SH "DESCRIPTION"
.PP
Displays information about each Gfarm file descriptors, if neither
\fB\-C\fR
nor
\fB\-G\fR
is specified\&. The USER field shows username, the GPID field shows Gfarm process ID, the FD field shows Gfarm file descriptor number, if the character just after the descriptor number is \*(Aqr\*(Aq, it means read\-only open, if the character is \*(Aqw\*(Aq, it means write\-only open, and if the character is \*(Aqu\*(Aq, it means read\-write open, the TYPE fields shows the type of the inode (REG is a file, DIR is a directory and LNK is a symbolic link), the INODE field shows the inode number, the GEN field shows the generation number of the inode, the SIZE/OFF shows the seek\-offset value if the inode is a directory, or the file size if the inode is a file, the CLIENT field shows hostname and port number of the client which is connecting to the gfmd, the GFSD field shows hostname and port number of the gfsd which is connecting to the gfmd\&.
.PP
If
\fB\-C\fR
option is specified, this command shows only hostnames of clients which are opening descriptors\&.
.PP
If
\fB\-G\fR
option is specified, this command shows only hostnames of gfsd which are opening file replicas\&.
