``` {program} caget

|

## Description
|
||||
|
||||
Get and print value for PV(s).
|
||||
|
||||
The values for one or multiple PVs are read and printed to stdout. The
|
||||
`DBR_...` format in which the data is read, the output format, and a
|
||||
number of details of how integer and float values are represented can be
|
||||
controlled using command line options.
|
||||
|
||||
When getting multiple PVs, their order on the command line is retained
|
||||
in the output.

||||
