/session: things about the command process their options.
similar method used as process the options for command:
cat.c c = getopt(argc, argv, "usvtebn")
ls.c c = getopt(argc, argv, "aAbcCdeEfFghHilLmnopqrRsStux1@vV")
mkdir.c c = getopt(argc, argv, "m:p")
Take cat.c as an example:
"usvtebn" flags are used, accordingly several global static variable used:
static int silent = 0; /* s flag */
static int visi_mode = 0; /* v flag */
static int visi_tab = 0; /* t flag */
static int visi_newline = 0; /* e flag */
static int bflg = 0; /* b flag */
static int nflg = 0; /* n flag */
