NAME

update -- update the parameters for a task on disk

USAGE

update task [task ...]

PARAMETERS

task
An IRAF task name.

DESCRIPTION

Normally when a task terminates the values of the task parameters used are stored for the next invocation of the task in a disk file in the users UPARM directory. However if the task parameters have been cached by the cache command, this will not be done until the CL terminates. In the case of a background job, automatic updating of parameters is disabled. The update command is used to force the parameters for a task to be updated on disk.

EXAMPLE

1. Update the parameters for the page task.

cl> update page

BUGS

The parameter set is only updated on disk if a parameter has been modified since the last update.
