tcal

TCAL(1) 						      General Commands Manual							   TCAL(1)

NAME

       Tcal - runs the Gcal program with the date of tomorrow's day.

SYNOPSIS

       tcal [--help | --version] | [--shift=[+|-]number] [Argument...]

DESCRIPTION

       Tcal  is  a program which runs gcal with a date set one day ahead (equivalent the --shift=1 option). All given arguments are passed unmodi-
       fied to the Gcal program. If the Gcal program shall be called with another date than tomorrow's date, this desired date can be selected	by
       using  the --shift=[+|-]number option, in which [+|-]number is the distance of days the desired date is distant from the actual date (works
       only for Gregorian years). The --shift option must be given before all other arguments which are passed to the Gcal program. An exit status
       of 0 means all processing is successfully done, any other value means an error has occured.

OPTIONS

       --help Print a usage message listing all available options, then exit successfully.

       --version
	      Print the version number, then exit successfully.

       --shift=[+|-]number
	      Define the displacement in [+|-]number days the desired date is distant from the actual date.

ENVIRONMENT

       GCALPROG
	      The  GCALPROG  environment  variable contains the file name of the executable Gcal program, which is used by Tcal to call Gcal. This
	      takes precedence over the file name `gcal', which is burned-in during the compilation step of tcal.
