NAME
pfilter - positions the filter wheel
SYNOPSIS
pfilter [name] [all] [home]
DESCRIPTION
This positions the filter wheel to the filter `name' specified in the command
line.
If no arguments are specified it returns the name of the filter. If the
`all' switch is specified it prints out the present Filter number and names
of the filter bolt.
The `home' option runs the filter to the `home' position
and prints out the number of error counts (see tserver.man section on
position_filter.)
Caution The `home' flag returns the filter
to slot number 0 unless a filter is specified in the command
line.
Note that filter names are case sensitive and should not contain embedded
spaces.
If and error occurs or the program cannot find the filter the status flag is
set to 1, otherwise it is
0.
All the data are taken from the file $HOME_DIR/
ait.config.
