About a year and half or so ago me and a friend set up Debian on a PS3. For a while I could not boot into the ps3 but managed to get it running again. I was very excited to get back in a play on the Debian distro we installed until I found neither of us could remember the password he put on it.

Hi guys,
Is there a way to assign curent time to PS4 variable in ksh. My goal is to have each line produced by 'set -x' command to have a time stamp.
Here is my code:

export PS4="`date` "

dctopnm
DCTOPNM(1) DICOM PS3 - DICOM image to PNM file DCTOPNM(1)
NAME
dctopnm - ACR/NEMA DICOM PS3 ... DICOM PS3 - DICOM image to PNM file
SYNOPSIS
dctopnm [ -v|verbose ] [ -quiet|silent ]
DESCRIPTION
dctopnm reads the named dicom or acr-nema input file and copies the raw image pixel data to a PNM file after adding a PGM or PPM header.
The input file must be unencapsulated, and in the case of > 8 bit data, in the same byte order as desired in the output, since the raw
bytes are copied from input to output without any conversion. Use dccp(1) first to change the encoding if necessary.
Only the necessary number of bytes to encode the pixel data will be written (based on rows, columns, number of frames, samples per pixel
and bits allocated); this means that for an odd number of bytes the extra DICOM padding byte will not be copied to the raw output. This
prevents netpbm utilities freaking out with an error "reading magic number" if the padding byte is present. If any of the necessary
attributes to calculate the correct pixel data length are missing, all encoded bytes will be written.
OPTIONS
The PNM output goes where it is specified or standard out. The verbose output goes to standard error.
The basic input switches are described in dcintro(1). Options specific to this program are:
-quiet|silent
Suppress the normal description of image parameters.
-verbose
Display byte offset from file start and message start, in hexadecimal, and dump contents while reading, once read, during replace-
ment, and before writing.
