# helpmidas(1)

Standalone GUI help for MIDAS.

## NAME

helpmidas - Standalone GUI help for MIDAS.

## SYNOPSIS

**helpmidas**\
 \[ **-h** *midashome* \] \[ **-r** *midvers* \] \
 \[ **-d** *display* \] \[ **-m** *mid\_work* \]

## DESCRIPTION

*helpmidas* starts a standalone GUI help for MIDAS.

Without arguments, *helpmidas* initiates a MIDAS help session with default definitions. Some of these definitions can be modified with arguments in the command line of *helpmidas* or by environment variables. Arguments in the command line are taken with preference to environment variables.

## OPTIONS

*helpmidas* has been configured by the operator at installation time to start the binary XHelp.exe located in  *$MIDASHOME0/$MIDVERS0/gui/exec*directory (defined internally in the script). However alternative releases can be specified using the:

- **-h** *midashome*

  Home directory for MIDAS. Absolute pathname containing, at least, one release  of MIDAS. It may also contain subdirectories for demo and calibration data.

- **-r** *midvers*

  Release of MIDAS to be executed. It must be a subdirectory under  *midashome.*

- **-d** *display*

  Specifies another X server for the display and graphical MIDAS windows ( **NOTE:** be aware of allowed access to a remote X server using the [*xhost*(1)](/xhost/1.md) command.)

- **-m** *mid\_work*

  Specifies the MIDAS startup directory (default: $HOME/midwork). This GUI  will create this directory if it does not exist and uses in to keep some  temporary files.

## ENVIRONMENT

*helpmidas* can also use the following definitions in  the environment with the same performance as previous described arguments.\

- **MIDASHOME**

  Home directory for MIDAS.

- **MIDVERS**

  Release of MIDAS.

- **DISPLAY**

  X server for the display and graphical MIDAS windows.

- **MID\_WORK**

  Startup directory for MIDAS.
