Citing a linux manual page in bibtex?

I'd like to cite the man page for the iostat command. I found the @manual entry. Is this the accepted way of citing Linux man pages?

I've populated the fields below based on what the man page says on my system.

@manual{iostat,
 title      = "iostat(1) Linux User's Manual",
 %author        = "",
 %organization  = "",
 %address   = "",
 %edition   = "",
 year       = "2013",
 month      = "July",
 %note      = "",
}
