NAME
  p - print the value of an expression

SYNOPSIS
  p [-x|-d][-u] expression

DESCRIPTION
  This command passes its arguments on to gdb "print" command for evaluation.

    expression   The expression to be evaluated.
            -x  override default output format with hexadecimal format.
            -d  override default output format with decimal format.
            -u  the expression evaluates to a user address reference.

  The default output format is decimal, but that can be changed at any time
  with the two built-in aliases "hex" and "dec".  Alternatively, there
  are two other built-in aliases, "px" and "pd", which force the command
  output to be displayed in hexadecimal or decimal, without changing the
  default mode.

  Print the contents of jiffies:

    crash> p jiffies
    jiffies = $6 = 166532620
    crash> px jiffies
    jiffies = $7 = 0x9ed174b
    crash> pd jiffies
    jiffies = $8 = 166533160
