List section and total sizes for an archive or object file (POSIX)


size_variant [ -A | -B ]
     [ --help ]  [ -d | -o | -x ]
     [ --target=bfdname ]  [ -V ]  
     [ objfile... ]

Runs on:

All supported hosts.


The size_variant depends on the target platform, as follows:

Target platform: size_variant:
All targets, plus native ntomulti-size
ARM ntoarm-size
PowerPC ntoppc-size
SH4 ntosh-size
x86 ntox86-size
Using one of these options, you can choose whether the output from size resembles output from System V size (using -A), or Berkeley size (using -B). The default is the one-line format similar to Berkeley's.

Here's an example of the Berkeley (default) format of output from size:

size -B ranlib size
text    data    bss     dec     hex     filename
294880  81920   11592   388392  5ed28   ranlib
294880  81920   11888   388688  5ee50   size

This is the same data, but displayed closer to System V conventions:

size -A ranlib size
ranlib  :
section         size         addr
.text         294880         8192       
.data          81920       303104       
.bss           11592       385024       
Total         388392    

size  :
section         size         addr
.text         294880         8192       
.data          81920       303104       
.bss           11888       385024       
Total         388688

Show a summary of acceptable arguments and options.
Specify that the object-code format for objfile is bfdname. This option may not be necessary; size can automatically recognize many formats. For more information, see "Target Selection" in the appendix Selecting the Target System.


The size utility lists the section sizes and the total size for each of the object or archive files objfile in its argument list. By default, one line of output is generated for each object file or each module in an archive.

The objfile... arguments identify the object files to be examined. If no files are specified, a.out is used.
