lsof manpage says the following about the
TYPE is the type of the node associated with the file - e.g., GDIR, GREG, VDIR, VREG, etc.
Can someone please explain (or point me to a link which explains) what these mean. I have tried googling on these but all the links take me to the lsof man page only.
If you find a link, do tell me how you googled it :)
