AIX Version 4.3 Commands Reference, Volume 5
size Command
Purpose
Displays the section sizes of the Extended Common Object File Format (XCOFF) object files.
size [ -d | -o | -x ] [ -f ] [ -V ]
[ -X
{32|64|32_64}]
File [ File ... ]
Description
The size command writes to standard output the number of bytes required by all sections, along with their sum for each XCOFF file. If the -f flag is specified, the section name follows the section size.
Flags
The output is in decimal notation unless you change the output with the following flags:
-d |
Writes in decimal notation. |
-f |
Writes the section name in parenthesis following the section size. |
-o |
Writes in octal notation. |
-x |
Writes in hexadecimal notation. |
-X mode |
Specifies the type of object file size should examine. The mode must be one
of the following:
32 |
Processes only 32-bit object files |
64 |
Processes only 64-bit object files |
32_64 |
Processes both 32-bit and 64-bit object files |
The default is to process 32-bit object files (ignore 64-bit objects). The
mode can also be
set with the OBJECT_MODE environment variable. For example, OBJECT_MODE=64 causes
size to process any 64-bit objects and ignore 32-bit objects. The -X flag overrides the
OBJECT_MODE variable. |
-V |
Prints the version number of the size command. |
Examples
- To display the size of the a.out file in decimal, enter:
size
This displays the size in bytes of the executable a.out file. The size of each section of the object file is given, followed by the total:
3720 + 1752 + 4152 = 9624
- To display the size of an object file in octal, enter:
size -o driver.o
This displays the size of the driver.o object file in octal.
- To display the size of several object files in hexadecimal, enter:
size -x *.o
This displays in hexadecimal the size of each file ending with .o in the current directory.
