# tcal(1)

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

## 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 unmodified 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 occurred.

## 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***.*
