Unix in a Nutshell, 4th Edition

Name

print

Synopsis

print [/format] [expression]

Print the value of expression. If the first argument is "/" and format, use the format to print the expression. Omitting expression prints the previous expression, allowing you to use a different format to see the same value. The allowed format values are a subset of the format items for the x command; see also x, later in this section.

Print Formats

a	Print the value as an address. The address is printed as both an absolute (hexadecimal) address, and as an offset from the nearest symbol.
c	Print the value as a character constant.
d	Print the value as a signed decimal integer.
f	Print the value as a floating point number.
o	Print the value as an octal integer.
t	Print the value as a binary integer (t stands for “two”).
u	Print the value as an unsigned decimal integer.
x	Print the value as a hexadecimal integer.

Example

Print a wide character value as a regular character:

    (gdb) print tmp->sub.val.wsp
    $2 = (wchar_t *) 0x99f0910
    (gdb) print/c *$2
    $3 = 97 'a'
