37.Sh DESCRIPTION
38.Nm Crontab
39is the program used to install, deinstall or list the tables
40used to drive the
41.Xr cron 8
42daemon in Vixie Cron. Each user can have their own crontab, and though
43these are files in
44.Pa /var ,
45they are not intended to be edited directly.
46.Pp
47If the
48.Pa allow
49file exists, then you must be listed therein in order to be allowed to use
50this command. If the
51.Pa allow
52file does not exist but the
53.Pa deny
54file does exist, then you must
55.Em not
56be listed in the
57.Pa deny
58file in order to use this command. If neither of these files exists, then
59depending on site-dependent configuration parameters, only the super user
60will be allowed to use this command, or all users will be able to use this
61command.
62.Pp
63The first form of this command is used to install a new crontab from some
64named file or standard input if the pseudo-filename ``-'' is given.
65.Pp
66The following options are available:
67.Bl -tag -width indent
68.It Fl u
69Specify the name of the user whose crontab is to be
70tweaked. If this option is not given,
71.Nm
72examines "your" crontab, i.e., the crontab of the person executing the
73command. Note that
74.Xr su 8
75can confuse
76.Nm
77and that if you are running inside of
78.Xr su 8
79you should always use the
80.Fl u
81option for safety's sake.
82.It Fl l
83Display the current crontab on standard output.
84.It Fl r
85Remove the current crontab.
86.It Fl e
87Edit the current crontab using the editor specified by
88the
89.Ev VISUAL
90or
91.Ev EDITOR
92environment variables. After you exit
93from the editor, the modified crontab will be installed automatically.

104The

108This new command syntax
109differs from previous versions of Vixie Cron, as well as from the classic

112A fairly informative usage message appears if you run it with a bad command
