From man bash, similar in man ksh
Quote:
PS1 The value of this parameter is expanded (see PROMPTING below) and used as the primary prompt string. The default value is ``\s-\v\$ ''.
PS2 The value of this parameter is expanded as with PS1 and used as the secondary prompt string. The default is ``> ''.
PS3 The value of this parameter is used as the prompt for the select command (see SHELL GRAMMAR above).
PS4 The value of this parameter is expanded as with PS1 and the value is printed before each command bash displays during an execution trace. The first character of PS4 is replicated multiple times, as necessary, to indicate multiple levels of indirection. The default is ``+ ''.

DCSORT(1)					      DICOM PS3 - Make sorted list of images						 DCSORT(1)

NAME
dcsort - ACR/NEMA DICOM PS3 ... DICOM PS3 - Make sorted list of images SYNOPSIS
dcsort " inputfile1 [ inputfile2 ... ]" [ -v|verbose ] [ -vv|veryverbose ] [ -vvv|veryveryverbose ] [ -index ] [ -show ] [ -interval ] [ -tolerance mm ] [ -check ] [ -checkFoR ] [ -descending ] [ -sortby|k attributename ] DESCRIPTION
dcsort reads the named dicom input files and sorts them by the specified sort key. The sort key should be a single valued numeric attribute, with the exception of ImageOrientationPatient and ImagePositionPatient which are handled as special cases. There is no output by default unless the index or verbose options are specified. OPTIONS
The output and errors go to standard error. The basic input switches are described in dcintro(1). Options specific to this program are: -index Creates a first column of output that is the index in the sort order, starting from 0, and a second column that is the filename. -show Show the value of the sort key after the file name with the -index option -interval Show the interval between values of the sort key, or an error if not equal -tolerance mm The tolerance value in mm to use when comparing intervals between slices; defaults to +/- 0.01 mm if unspecified -check Check that all the images are from the same series. -checkFoR Check that all the images have the same Frame of Reference (UID). -descending Sort in descending, rather than the default ascending, order. -sortby|k attributename Specify attributename as the sort key. ENVIRONMENT
EXAMPLES
% dcsort -index -sortby SliceLocation ./1/[0-9]* 0 ./1/1 1 ./1/2 FILES
